Note: the Sender parameter of WakeMainThread will be Nil for such threads. This is Delphi compatible.
rtl/objpas/classes/classesh.inc, TThread:
+ TThreadQueueEntry: new field ThreadID so that entries with Thread = Nil can be removed
rtl/objpas/classes/classes.inc, TThread:
* InitSynchronizeEvent: setup ThreadID field
* Synchronize: use a local TThreadQueueEntry if no TThread instance was passed in
* Queue: setup ThreadID
* RemoveQueueEvents: also check for ThreadID when trying to find the current thread

functionality with RTLEvent:
o the thread manager semaphore functionality isn't used for anything else,
and the main difference between mutex/condvar and semaphores is that the
latter can be used for IPC (while the thread manager is always used
within a single process) and that they are counting (but since a thread
can only suspend itself nowadays, it cannot be suspended recursively)
o OS X sandboxing does not support the use of semaphores (or rather: Apple
does not allow sandboxing rules that enable the use of IPC semaphores in
the appstore)

(still not sure if it's a good idea, but trying, at least, is harmless - we
can always rollback to integer being equal to longint)

rtl/objpas/classes/classesh.inc, TStringList:
* rename the private ExchangeItems to ExchangeItemsInt and allow inlining
+ add a protected virtual ExchangeItems
rtl/objpas/classes/stringl.inc, TStringList:
* Exchange: call ExchangeItemsInt
+ let default implementation of ExchangeItems simply call ExchangeItemsInt
* QuickSort: call ExchangeItemsInt directly if there is no override otherwise call ExchangeItems
+ added test

Also adjusted all Windows (Win32/64/CE) units to define a "UNICODE" if "FPC_OS_UNICODE" is defined (except the Jedi units).
Also the common RTL units that checked for UNICODE now check for FPC_OS_UNICODE.

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.
