d3660fec31 Implement support for parsing "generic [class] procedure" and "generic [class] function" in non-Delphi modes. Since "generic" is a prefix it is quite ugly to implement, but from a Pascal language point of view it fits better than "procedure generic xyz".
Supporting such a prefix of course means that all section handling code ("var", "type", etc.) needs to respect the case of a "generic" token followed by "function", "procedure" or "class" and thus abort doing its own business.
Maybe I'll find the time somewhen in the future to rework the parser (plus scanner?) a bit so that code like this gets more easy to add and more importantly less ugly.

pdecsub.pas:
  * extend parse_proc_dec() and parse_record_method_dec() so that they can be told that they are supposed to handle the to be parsed function/procedure/method header as a generic
pdecvar.pas:
  + new entry for tvar_dec_option named "vd_check_generic" to tell read_var_decls() and read_record_fields() to look out for "generic"
  * extend read_var_decls() and read_record_fields() to check for "generic" if needed and to clean up correctly if it is encountered
pdecl.pas:
  * the section handling procedures types_dec(), resourcestring_dec(), var_dec(), threadvar_dec() and consts_dec() all return whether they had encountered a "generic" token that was followed by one of $
pdecobj.pas:
  * extend method_dec() to take a parameter that says whether the method is supposed to be a generic one
  * parse_object_members: while read_record_fields() can handle "generic" we also need to handle the case of "generic" if no fields are allowed anymore
psub.pas:
  * extend read_proc() by the possibility to tell it that the procedure/function to be parsed is supposed to be generic
  * adjust read_declarations() and read_interface_declarations() to keep track of parsed "generic" tokens and to pass them on accordingly
ptype.pas:
  * parse_record_members: same remark as for pdecobj.parse_object_members

639a59df92 Added support for partial specialization. This should fix a few problems with generics, the tests for which will be added in the next days after I've verified them.
For partial specialization only the declaration is reparsed, but not method bodies.

The way generic parameters are passed around inside the compiler is changed: instead of creating new type symbols we keep a (name,def) pair so that the code in insert_generic_parameter_types can decide whether it needs to add a type symbol (for new undefined defs) or not (for real types and undefined defs that were passed on from the parent generic). This required the tfpobjectlist type of the genericlist variables/parameters to be changed to tfphashobjectlist.

For correctly parsing Delphi specializations as parameters in functions of records (or objects) the relationship between the def and its typesym must already be established during the parsing. For this the checks for forcing a "type is not completely defined" message needed to be adjusted to correctly handle nested types as well. This should as a sideeffect also allow the usage of nested constants, etc like was fixed for classes some months ago.

ToDo: 
  - if a generic is specialized with only fully defined types then we could generate the in the unit where it's used. This is not yet done.
  - currently we don't specialize generics that are currently parsed; maybe this could be improved in the future for better type compatibility checks
  - check whether the pausing of token recording for partial specializations works correct in context of hint modifiers

pgenutil.pas:
  * parse_generic_parameters: return a tfphashobjectlist instead of a tfpobjectlist (requires a few type adjustments in various other declarations)
  * maybe_insert_generic_rename_symbol, insert_generic_parameter_types: change genericlist from tfpobjectlist to tfphashobjectlist
  * parse_generic_specialization_types_internal: use is_generic instead of checking for df_generic
  * generate_specialization:
      + add a nested function to disable the requirement to check for method bodies
      * use the "simple" parameter parsing only for error recovery
      * instead of already creating a new type symbol for a parameter we use the found symbol's name and its def and maybe create it later on (therefor the type of tfpobjectlist was changed to tfphashobjectlist)
      * a partial specialization is specialized into the symtable of the def it is specialized in instead of one of the two global symtables
      * for now we handle partial specializations of generics we are currently parsing like before
      * don't continue recording generic tokens while we do a partial specialization
      * use the new unset_forwarddef function on the newly created defs
  * insert_generic_parameter_types: only create a new type symbol if the found type symbol does not yet have an owner (thus was freshly created for this generic declaration)

pdecobj.pas, object_dec:
  * change type of genericlist from tfpobjectlist to tfphashobjectlist
  * set the type sym for all object types that can be generic or inside a generic (needed for correctly parsing Delphi style generic declarations)

pdecsub.pas, parse_proc_head:
  * consume_generic_interface: always generate the specialization name as now all generics are "specialized" inside a generic
  * the assumption that the def index numbers are the same is no longer true as the genericdef might contain the defs of partial specializations which are not generated for full specializations

pdecvar.pas, read_record_fields:
  * we also need to check nested types whether they contain a not yet completely parsed record or object

ptype.pas:
  * read_named_type: 
      * change genericlist from tfpobjectlist to tfphashobjectlist
      * pass the typesymbol along to record_dec
  * resolve_forward_types: use is_generic instead of checking for df_generic
  * single_type: 
      * use is_generic instead of checking for df_generic
      * no need to check generic parameters
  * parse_record_members:
      + add parameter for the record's type symbol
      * setup the typesym <=> def relationship
  + record_dec: add parameter for the type symbol and pass it to parse_record_members
  * read_named_type, expr_type: use is_generic instead of checking for df_generic
  * array_dec & procvar_dec: change genericlist from tfpobjectlist to tfphashobjectlist

symdef.pas, tstoreddef:
  * improve the checks used in is_generic and is_specialization to really only work on true generics and true (and partial) specializations respectively
  * don't search the type parameters in the symtable, but store them in the PPU and load them from there
  - remove fillgenericparas method (including the calls in the descendants tarraydef, tprocvardef, tobjectdef and trecorddef)

defcmp.pas, compare_defs_ext:
  * handle partial specializations: specializations with only undefineddefs are compatible to generic defs

pdecl.pas, types_dec:
  * switch generictypelist from tfpobjectlist to tfphashobjectlist

ppu.pas:
  * increase PPU version

+ added tests that ensure that "not completely defined" checks for records (and objects) still work correctly

b57c95043f + support overriding tdef/tsym methods with target-specific functionality:
o made all (non-abstract) tdef and tsym constructors virtual
   o added c*def/c*sym classref types for every (non-abstract) t*def/t*sym
     class
   o added cpusym unit for every architecture that derives a tcpu*def/tcpu*sym
     class from the base classes, and initialises the c*def/c*sym classes with
     them. This is done so that the llvm target will be able to derive from
     the tcpu*def/sym classes without umpteen ifdefs, and it also means that
     the WPO can devirtualise everything because the c* variables are only
     initialised with one class type
   o replaced all t*def/t*sym constructor calls with c*def/c*sym constructor
     calls

4aa05f5133 + support for automatically generating setters/getters for properties on the
JVM target, since Java bytecode itself has no support for properties and
    hence exposing properties to external Java code can only be done through
    getters/setters. Use the new parameters to do so:
      -CTautogetterprefix=XXX
      -CTautosetterprefix=YYY
    The getter/setter will get the same visibility as the property. If a
    getter/setter with the same naming convention was already specified for a
    property and this getter/setter is declared in the same class as the
    property, then the visibility of this existing getter/setter is
    modified and no new routine is generated.

    Newly generated getters/setters are virtual methods, because that is
    the only way in Java bytecode to allow redefining these getters/setters
    in child classes. However, that also means that using these switches can
    change the behvaviour of code, since normally the used property definition
    is only determined by the declared type of its associated class instance,
    and not by the actual instance type. The compiler will therefore warn when
    such an automatically generated getter/setter is overridden by another
    automatically generated getter/setter in a child class.

3798b79fd7 + optimization that (re)orders instance fields of Delphi-style classes in
order to minimise memory losses due to alignment padding. Not yet enabled
    by default at any optimization level, but can be (de)activated separately
    via -Oo(no)orderfields
   o added separate tdef.structalignment method that returns the alignment
     of a type when it appears in a record/object/class (factors out
     AIX-specific double alignment in structs)
   o changed the handling of the offset of a delegate interface
     implemented via a field, by taking the field offset on demand
     rather than at declaration time (because the ordering optimization
     causes the offsets of fields to be unknown until the entire
     declaration has been parsed)

aee5380ae0 * merged trunk up to r20882
o support for the new codepage-aware ansistrings in the jvm branch
   o empty ansistrings are now always represented by a nil pointer rather than
     by an empty string, because an empty string also has a code page which
     can confuse code (although this will make ansistrings harder to use
     in Java code)
   o more string helpers code shared between the general and jvm rtl
   o support for indexbyte/word in the jvm rtl (warning: first parameter
     is an open array rather than an untyped parameter there, so
     indexchar(pcharvar^,10,0) will be equivalent to
     indexchar[pcharvar^],10,0) there, which is different from what is
     intended; changing it to an untyped parameter wouldn't help though)
   o default() support is not yet complete
   o calling fpcres is currently broken due to limitations in
     sysutils.executeprocess() regarding handling unix quoting and
     the compiler using the same command lines for scripts and directly
     calling external programs
   o compiling the Java compiler currently requires adding ALLOW_WARNINGS=1

f984a3d74e - removed optimization that pops the current symtable off the symtablestack
if it cannot contain local type definitions before looking up the type of
    a field, because the type of a field may be a new type definition (e.g. an
    inline record definition) and such type definitions must be added to the

d752ce2c11 compiler:
- postpone insertion of hidden params into record methods after the full record parse to prevent interface and implementation difference because of the possible record size change after the method parse (issue #0021044)
  - skip hidden arguments during methods search for a property setter because of the above change and also for consistency with getter method search
  - test

The changes regarding pretty names for generics and token buffer endianess were integrated into my changes. Not every call to generate_specialization is fixed though, so compilation will fail.
