Sync to Wine-20050725:

Phil Krylov <phil@newstar.rinet.ru>
- Added some useful TRACEs.
- Allow NULL parameter for WM_SETTEXT in RichEdit.
- Implemented EM_LINELENGTH RichEdit message.
- Fixed EM_LINEINDEX handler and added EM_LINEFROMCHAR handler.
- Implemented EM_EXLINEFROMCHAR, EM_LINEINDEX, EM_FINDTEXT,
  EM_FINDTEXTW, EM_FINDTEXTEX, and EM_FINDTEXTEXW messages.
- Fixed a comment about EM_STREAMIN.
- Implemented EM_GETLINECOUNT RichEdit message.
- Fixed EM_GETCHARFORMAT for selection containing a single character.
- Fixed an off-by-one error in EM_GETLINECOUNT handler.
- Fixed an off-by-one error in EM_STREAMOUT handler for non-Unicode
  plain text output.
- Fixed another couple of EM_STREAMOUT bugs.
- Removed junk from UTF-8 RTF output.
- Added emulation of RichEdit 1.0 behaviour when the 1.0 window class is
  being used. This emulation (introduced in M$ RichEdit 3.0) counts
  paragraph endings as 2 characters (CR+LF) instead of 1 (CR).
- Added EM_GETZOOM and EM_SETZOOM RichEdit message handlers.
- Added some missing but useful items to the TODO list.
Felix Nawothnig <felix.nawothnig@t-online.de>
- Check structure size and fix return values in EM_GETCHARFORMAT.
Aric Stewart <aric@codeweavers.com>
- Implementation for EM_GETTEXTEX.
Daniel Remenak <dtremenak@gmail.com>
- Basic handling of EM_SETTEXTEX.
Stefan Huehner <stefan@huehner.org>
- Make functions static to fix -Wmissing-declarations warnings.
- Change some char* to const char* to fix warnigns.
- Make some function static.
- Fix -Wmissing-declarations warnings.
