type-safe way (for LLVM, and also internal consistency checking between
the VMT as generated in nobj.pas and ncgvmt.pas)

* Unit finalization executes arbitrarily large amount of code. Doing it when error occurred can cause
other errors, overwriting the original error information.
* Code that prints error message depends on everything and a kitchen sink (most notably, Unicode manager
and lineinfo unit). Running it after finalizing units can be successful only by coincidence.
* Last but not least, this sequence (ExitProc -> print RTE -> finalize units) is same as one used in Delphi.

Each port that allows the usage of dynamic libraries should call InitSystemDynLibs during initialization of the System unit.
The DynLibs unit has been adjusted to be a forwarder for the functions that now reside in the System unit (for backwards compatiblity just in case). Additionally the unit will register the DynLibsManager if it doesn't reside in the System unit anyway.
Currently only the Windows targets (Win32, Win64 and WinCE) implement the DynLibsManager inside the System unit. For other systems using the LoadLibrary, etc. functions will lead to a run error/exception.
If a port wants to implement its own DynLibsManager then it needs to define DISABLE_NO_DYNLIBS_MANAGER. TLibHandle, NilHandle and optionally TOrdinalEntry (it's set to SizeUInt otherwise) should be defined in sysdlh.inc which needs to be enabled using the define FPC_SYSTEM_HAS_SYSDLH (because there are targets which have FEATURE_DYNLIBS enabled, but don't support them... e.g. powerpc-wii -.-).
The DynLibsManager contains methods for loading a library based on a RawByteString and based on a UnicodeString. BOTH should be implemented, but internally one can forward to the other.
The loading by ordinal *can* be be implemented. If it is set to Nil then the implementation of GetProcAddress(lib,ordinal) will return Nil.
+ new functions SetDynLibsManager and GetDynLibsManager to set and retrieve the current DynLibsManager
* provide interface of DynLibs unit in unit System

be included at the start of the implementation of the system unit (before
the rest of except.inc)
* catch declarations in/loading from the system unit of the TExceptAddr type
* use this type instead of hardcoded size constants in the compiler
* in generic code that is active for all targets, puts its use in a virtual
method since it's only valid for targets using setjmp/longjmp-style
exception handling (and the record is not defined at all in the JVM RTL)

- rm ifdefs for i8086 far code memory model when doing stack traces. The
compiler will now choose the correct overload of HexStr according to the
CodePointer type.

* As a first part of cleanup, replaced StackTop with function returning StackBottom+StackLength.
* On Win32 and Win64, StackTop returns the stack base from TIB instead.

+ codepage support for textrec/filerec and the above routines
* textrec/filerec now store the filename by default using widechar. It is
possible to switch back to ansichars using the FPC_ANSI_TEXTFILEREC define.
In that case, from now on the filename will always be stored in
DefaultFileSystemEncoding
* fixed potential buffer overflows and non-null-terminated file names in
textrec/filerec
+ dodirseparators(pwidechar), changed the dodirseparators(pchar/pwidechar)
parameters into var-parameters and gave those routines an extra parameter
that indicates whether the p(wide)char can be changed in place if
necessary or whether a copy must be made first (avoids us having to make
all strings always unique everywhere, because they might be changed on
some platforms via a pchar)
* do_open/do_erase/do_rename got extra boolean parameters indicating whether
the passed pchars point to data that can be freely changed (to pass on to
dodirseparators() if applicable)
* objects.pp: force assign(pchar) to be called, because
assign(array[0..255]) cannot choose between pchar and rawbytestring
versions (and removing the pchar version means that assign(pchar) will
be mapped to assign(shortstring) in {$h-})
* fixed up some routines in other units that depend on the format of
the textrec/filerec.name field
git-svn-id: branches/cpstrrtl@25137 -
* renamed platform-specific pchar versions of those rouines to do_*() and
changed them to either rawbytestring or unicodestring depending on the
FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API setting
* implemented generic shortstring versions of those routines on top of either
rawbytestring or unicodestring depending on the API-kind (in case of the
embedded target, if ansistring are not supported they will map directly
to shortstring routines instead)
* all platform-specific *dir() routines with rawbytestring parameters now
receive their parameters in DefaultFileSystemCodePage
- removed no longer required ansistring variants from the objpas unit
- removed no longer required FPC_SYS_MKDIR etc aliases
* factored out empty string and inoutres<>0 checks from platform-specific
*dir() routines to generic ones
o platform-specific notes:
o amiga/morphos: check new pathconv(rawbytestring) function
o macos TODO: convert PathArgToFSSpec (and the routines it calls) to
rawbytestring
o nativent: added SysUnicodeStringToNtStr() function
o wii: convert dirio callbacks to use rawbytestring to avoid conversion
+ test for unicode mk/ch/rm/getdir()
git-svn-id: branches/cpstrrtl@25048 -
getdir(rawbytestring):rawbytestring so it can accept strings in any
encoding and cleanly return results in DefaultRTLFileSystemCodePage
+ getdir(unicodestring):unicodestring
* renamed the getdir implementation of all platforms except for embedded-
without-ansistring-support to do_getdir(), and depending on the
FPCRTL_FILESYSTEM_SINGLE_BYTE_API/FPCRTL_FILESYSTEM_TWO_BYTE_API define
changed its shortstring parameter to ansistring or unicodestring. The
do_getdir(rawbytestring) routine should just set the code page of the
return value to DefaultFileSystemCodePage without conversion (not
DefaultRTLFileSystemCodePage with conversion, that conversion is performed
in getdir if necessary; this avoids double conversions in case
getdir(unicodestring) is called)
+ generic getdir(shortstring) for platforms supporting either ansistrings or widestrings
o platform maintainers:
o OS/2: adjust code to supports paths > 255 characters if those are supported
o Wii: adjust used callback to use rawbytestring to support paths > 255 characters and
avoid shortstring->rawbytestring conversion overhead
o Windows: GetCurrentDirectoryW is now always used (to prevent data loss)
