Extract reading of the PPU/PCP version into tentryfile.
entfile.pas:
+ add new getversion method which uses the pointer returned by getheaderaddr to read the PPU/PCP version
ppu.pas:
- remove GetPPUVersion method
fppu.pas, pmodules.pas, utils/ppufiles.pp, utils/ppumove.pp, utils/ppuutils/ppudump.pp
* replace call to GetPPUVersion by call to getversion

Add a new target flag which determines whether the target supports dynamic packages or not.
systems.pas:
+ new flag tf_supports_packages
pmodules.pas, proc_package:
* error out when flag tf_supports_packages is not set for the current target
msg/errore.msg:
+ error message for when tf_supports_packages is missing and a package file is compiled

Extract functionality that is shared between the metadata files for units (PPU) and for packages (PCP) into a parent class called tentryfile
+ add new unit entfile which contains the new tentryfile class and related types and constants
* ppu.pas:
- remove methods, fields, types and constants which were moved to entfile.pas
* replace the parts of tppuheader shared with tentryheader by a field of type tentryheader
fppu.pas, pmodules.pas, utils/ppumove.pp, utils/ppuutils/ppudump.pp:
+ add entfile to uses
* adjust access to common header fields
node.pas, symdef.pas, symsym.pas, symtable.pas, wpoinfo.pas, utils/ppufiles.pp:
+ add entfile to uses

"don't free even if not registered"; use for defs that may not be written
to a ppu file, but that must nevertheless survive the compilation of the
current module
* mark all defs created for para locations as "don't free even if not
registered", because we don't discard and recalculate all para locations
after a module has been compiled (since that's not needed)
o solves issues if the paralocations for a routine in the interface of
unit A are calculated while the implementation of unit B gets
compiled, and a new reusable type is allocated at that point which
is not used anywhere else (after r32160)

o this allows us to write the VMTs earlier (before the synthetic method
implementations are generated), which means we can create new synthetic
methods while generating the VMTs (for interface trampolines)

* for now all objectdefs are created as registered
Note: an additional parameter instead of an overload is used for tobjectdef.create as otherwise both constructors would need to be overridden in potential descendant CPU-specific classes...

* for now all typesyms are created as registered
Note: an additional parameter instead of an overload is used for ttypesym.create as otherwise both constructors would need to be overridden in potential descendant CPU-specific classes...

o blocks are implemented as a variation of procedure variables
o declaration of a block variable: "test: procedure(c: char) is block;"
(C equivalent: (void)(^test)(char c) )
o the compiler automatically converts procedures/functions whose address
is passed to a block parameter or assigned to a block variable into
a "block". This consists of
1) generating a block descriptor (containing the size of the "block
literal" (see below) and the signature of the invocation function
encoded as an Objective-C selector)
2) generating a wrapper function around the original funcion (with C
calling convention), that has an extra first hidden parameter
(marked as vo_is_parentfp in the compiler) whose type is a pointer
to the describing "block literal"
3) generating the "block literal", which contains a pointer to an
external variable indicating whether this block captures context or
not, some flags (see compiler/blockutl.get_block_literal_flags for
info), a pointer to the wrapper function and a pointer to the
descriptor. In the future, it will also contain captured variables.
o right now, only global procedures/functions can be converted to blocks
(because they don't require state capturing). The next steps are (Object
Pascal) methods (not Objective-C methods, because Objective-C method
procvars don't exist) and finally nested functions
o on Mac OS X, the functionality will only work on Mac OS X 10.7 and later,
because we have to use the so-called "ABI.2010.3.16" to ensure that
our blocks aren't called as variadic functions by the runtime (which
came out after the Mac OS X 10.6 release)
o while the currently implemented functionality does not require any
library support at all, there's no use enabling it on other platforms
because unless it has been confirmed to work with a blocks runtime,
there's no point in using blocks (they're just somewhat bulky procvars
right now). Enabling it on other platforms (in combination with the
GNUStep Objective-C run time), should simply be a matter of adding
the right {$linklib xxx} statement to rtl/inc/blockrtl.pp file, adding
that file to Makefile.fpc for that platform and adding that platform
to the compiler/systems.systems_blocks_supported set

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

This improves compiling speed a bit (two iterations over symtables replaced by one, code generator is created once per unit rather than once per class).
In perspective it makes possible to reduce amount of generated smartlink sections and global labels.
