Replace the use of Henry Spencer's regex library with PCRE at the build
level and enable wxUSE_PCRE in wxRegEx code to switch to PCRE-based
implementation there.
Note that this has to be done unconditionally because there is no simple
way to select between the previously used regex library and PCRE at the
makefiles level.
We could still keep the possibility to use the system regex library
under Unix, but this doesn't seem to be worth doing, as we don't support
Unicode REs properly when using it (and never did), so drop support for
this too.
Use the same format as is used by MSVS itself to avoid spurious changes when
modifying the files. Notably:
- Use DOS end of line format (0D 0A).
- Add UTF-8 BOM (EF BB BF) to the beginning of the files.
- Do not put CR LF at the end of the last line in the file.
Closes https://github.com/wxWidgets/wxWidgets/pull/440
Having CRLF files in the repository with eol=crlf breaks just about
everything, e.g. any rebase/merge involving these files would fail.
Try to fix this by making sure the files use LF in the repository and CRLF is
only used in the working copy.
Get rid of version-specific MSVS project files, we can reuse the same projects
for all MSBuild-based versions, i.e. 2010, 2011 and 2013.
