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

use a single byte API for file system operations
+ FPCRTL_FILESYSTEM_TWO_BYTE_API define that is set for targets where we
use a single byte API for file system operations
o in principle, both can be set if both are supprted and implemented in
the RTL in order to minimise conversions depending on the scenario
git-svn-id: branches/cpstrrtl@24991 -
o resolved conflict in updated morphos sysutils unit
o moved code that had been added to the now deleted sysunix.inc to the
unix-specific block of the fpwidestring unit's init code
git-svn-id: branches/cpstrrtl@24913 -
* Build unixcp for all unix-like systems.
* Use the unixcp unit in cwstring instead of winiconv.inc.
- Deleted winiconv.inc
- Reverted r22410,r22411,r22428. The compiler will use the unixcp unit to get a default code page for ansistrings.

RTL units. Comes with a FPCRTL_FILESYSTEM_UTF8 define that can be
activated for targets whose single byte filesystem interface enforces
UTF-8; included in inc/systemh.inc and unix/cwstring.pp until now
+ DefaultFileSystemCodePage variable that holds the code page used for
communicating with the OS single byte file system APIs, and for the
strings returned by those same APIs. Initialized with
o the result of GetACP in the system unit of Windows platforms, except for
WinCE which uses UTF-8 since its file system OS API calls already use
the UTF-16 versions
o CP_UTF8 on Unix platforms with FPCRTL_FILESYSTEM_UTF8 defined, and with
DefaultSystemCodePage on other Unix platforms
o DefaultSystemCodePage on Java/Android JVM targets
+ DefaultRTLFileSystemCodePage variable that holds the code page used to
encode strings returned by RTL routines that return filenames obtained
from OS API calls. By default the same as DefaultFileSystemCodePage on
all platforms. Separate from DefaultFileSystemCodePage for clarity on
platforms that may use either utf-16 or single byte OS API calls to
send/receive file names (such as most Windows platforms)
+ new scpFileSystemSingleByte enum that can be passed to
GetStandardCodePage() to get the default code page for OS single byte file
system APIs, with implementations for Unix and Windows
+ SetMultiByteFileSystemCodePage() procedure to override the value of
DefaultFileSystemCodePage
In principle, in the long run unchanged programs only using generic
ansistrings and unicodestrings should (mostly) behave the same as in
FPC 2.6.0 as far as RTL-level file system APIs are concerned if
they set DefaultFileSystemCodePage and DefaultRTLFileSystemCodePage
to DefaultSystemCodePage at the start of their execution
