- Time has come to get rid of a slightly modified implementation of WINE's heap, which is a hack based on Windows 95's heap implementation, itself a hack of DOS memory management. It supported 3 out of the 18 possible NT Heap Flags, did not support custom allocation/deallocation routines, and was about 50-80x slower with fragmentation rates up to 500x higher when compared to NT's LFH (WINE is lucky because the advanced NT Heap features are used in kernel-mode usually, not in user-mode, and they are crossing their fingers for this being the same). Several high-end SQL/Database applications would significantly benefit from custom heap features provided by NT. Not to say about removing crappy support for a custom Commit routine and crappy support for User-defined flags and the User-defined value.
- So, the glorious moment for a new heap manager, which is (to remind you) a totally new heap manager, resembling real NT heap manager, based on data structures similar to Windows 2003 and Vista+'s heap structures, supporting advanced heap flags (e.g. useful for debugging), having substantially lower fragmentation rates (and thus speed and reliability), having native support for user-defined flags and user-defined values, also native support for a custom commit routine, which is very important for trunk's win32 subsystem. It also reserves, commits, decommits and frees memory on the fly, unlike existing heap manager which prefers to reserve and commit as much as possible, and doesn't decommit when it's no longer necessary. Not to say about support for per process heaps, with a proper lock, and a further support for a special so-called debug heap allocator (to be implemented in heapdbg.c) which will be useful for finding heap corruptions.
Yeah, I'm not a fun person :D

- Remove the old send message API and use NtUserMessageCall.
- Send messages do not pass the Ansi bit. This was evident during the hook changes. User32 knows the caller is Ansi and with a Unicode window user32 can make the apropate switch. Win32k on the other hand, assumes, based on the Unicode window the caller is Unicode. Hook tests enabled in send message, forces the call to win32k, and the Ansi product is Unicode data. Using NtUserMessageCall this bit can be passed forward to allow win32k to make the correct switch going to callback.

- Fail attempts to connect or disconnect a directory or device.
- Fail attempts to connect or disconnect a pipe by the client.

- Fixed SendNotifyMessage, thanks to Michael Martin callback changes. Fixed DispatchMessage when dealing with thread errors. Fixed all but one of the Get/PeekMessage wine tests. Fixed attaching threads to process information. Plus other fixes.
- Implemented support for QS bits, ReplyMessage (not fully correct), and others.
- Tested everything here, please post regressions so I can add more applications to the test list. This patch is synced with 49720 and 49772. After that there are graphic issues.
- Credits goes to wine for helping with diagnosing issues in the ReactOS message system.

patch by Samuel Serapion:
Implement MemorySectionName case for NtQueryVirtualMemory. Protect buffer access with SEH.
See issue #5753 for more details.

- Port findstr (incomplete, as author of this patch states, it may satisfy RosBE, .c .h and .rc files) from FreeDOS project. Needed for RosBE-on-ReactOS support.
See issue #5724 for more details.

- Carlo Bramix: MultiByteToWideChar() has just 6 and not 8 parameters, probably it's a forgetten copy/past from WideCharToMultiByte().
- Carlo Bramix: ConvertULargeInteger() should have its parameter 'Len' declared as UINT rather than 'INT'. This fixes a signed/unsigned mismatch warning.
See issue #5678 for more details.

- Jerome Gardou: Almost all of the ddraw->refcount winetests pass. One remains, due to the fact that IdirectDrawSurface::SetPalette is unimplemented. IDirectDraw::Createpalette is implemented too, but needs testing. There are no parameter checks.
- Comments from me: The patch is not build-tested, however I did my best to merge it to existing ddraw and I prefer the actual code to be in the repository rather than hanging in bugzilla for years (last comment to the patch is dated 29.10.2009).
See issue #4909 for more details.
