b513123062 Discard fully transparent alpha channel when loading bitmaps. 
Some bitmap files declare themselves to be 32bpp, normally indicating that
they have an alpha channel, but have only zeroes in their alpha data. Hence
loading them used to create fully transparent images which wasn't the desired
effect.

Fix this by simply discarding the alpha channel entirely if it turns out that
all pixels were fully transparent.

Closes #10915.

03647350fc No changes, just removed hard tabs and trailing white space. 
This commit is huge but there are no non-white-space changes in it.

Some files containing third-party sources (src/msw/wince/time.cpp,
src/x11/pango*.cpp) were left unchanged.

9a83f86094 Globally replace _T() with wxT(). 
Standardize on using a single macro across all wxWidgets sources and solve the name clash with Sun CC standard headers (see #10660).

43b2d5e7c3 Put braces around all calls to wxLogFunctions() inside an if statement. 
This suppresses all the remaining g++ -Wparentheses warnings and uses consistent style everywhere.

af58844636 Add information about the log message generation location to wxLog. 
This means that wxLog::DoLogRecord() can now retrieve the file name, line
number and the function where the message was logged.

An unfortunate consequence of this change is that now

	if ( condition )
		wxLogError("Whatever");

results in a warning from g++ 4.x with -Wparentehses, so extra parentheses had
to be added in many places.

Finally, also allow storing arbitrary attributes in wxLogRecordInfo. This had
to be added to implement our own overloaded wxLogStatus() and wxLogSysError()
and will probably be useful for the others as well.

8faef7ccbc document that CanRead() and GetImageCount() functions of wxImageHandlers do NOT modify the current stream position and that they require seekable streams; rename current GetImageCount() functions to DoGetImageCount() and put save-and-restore stream position logic in GetImageCount(); add comments in the various DoCanRead() and in DoGetImageCount() where the stream position is modified; remove unneeded SeekI(0) calls from DoCanRead() and DoGetImageCount() functions: they didn't allow to load images from non-seekable streams; implement forward-seeking in wxInputStream::SeekI() also for non-seekable streams

cff81649d6 Applied [ 594745 ] Fixes core dump under Forte 6U1 in imagbmp.cpp 
By John Skiff
I was getting a core dump under Solaris 2.6 when
storing images. My compiler is Forte 6 Update 1. The
problem was in imagbmp.cpp:

t@1 (l@1) signal BUS (invalid address alignment) in
wxANIHandler::DoCanRead at line 1304 in file "imagbmp.cpp"
1304 if ( FCC1 != *riff32 )
(dbx) p FCC1
FCC1 = 31064321
(dbx) p *riff32
*riff32 = 1380533830
(dbx)

I have tested the fix under Windows 2000, Solaris 2.6,
and Irix 6.5.
