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

* It fixes regression of tw16283b after r27169.
* BeOS, Haiku: added fpc_cpucodeinit to compensate for removal of SysInitFPU, it also enables use of CPU features like SSE.

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.

Especially for the introduction of the Queue method the internal Synchronize handling was modified. Instead of handling only one event there is now a queue of events which is walked completely when CheckSynchronize is called. Each entry in the queue can carry a PRTLEvent which will be signaled when the contained method has been executed and thus Synchronize methods can still be blocking.
Exceptions inside the queued methods are either handed back to the calling method for Synchronize events or raised directly (after leaving the queue in a valid state) to the caller of CheckSynchronize.
The way platform specific adjustments can be made to TThread was changed. Instead of implementing the Constructor and Destructor directly one now implements the methods SysCreate and SysDestroy which are called from the Constructor and Destructor respectively. All RTLs were adjusted for this and should be controlled by the platform maintainers for correct compilation (Unix works).
The new method NameThreadForDebugging has two overloaded variants: one with the thread name as AnsiString and one with the thread name as UnicodeString.
By default the AnsiString variant calls the UnicodeString variant and the latter needs to be implemented. This can be changed by defining THREADNAME_IS_ANSISTRING for a platform. Then the UnicodeString variant calls the AnsiString one and the AnsiString one needs to be implemented.
Also added was a global property CPUCount for the System unit. This property returns the number of virtual cores of the system.
New methods and functions that should be implemented per platform are:
System.GetCPUCount (default returns 1)
Classes.TThread.GetSystemTimes (default zeros the struct)
Classes.TThread.NameThreadForDebugging (default does nothing)
More detailed information about the added methods will be available in the feature announcement mail.

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
git-svn-id: branches/cpstrrtl@22466 -
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
to the make command line
