Similar to other system libraries, use the builtin version on Windows and macOS
and try to find the system library on Unix.
Find the correct PCRE2 library based on the code point width that will be used.
Using non-PCRE system regex library, which was the only build variant
when wxHAS_REGEX_ADVANCED was not defined, is not supported any more, so
simplify the code by not testing for it.
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.
This is not necessary any longer since the changes of 1b76ff4887
(Disable wxWebRequest tests on CI platforms without Python 3,
2021-05-16) as we require Python 3 for httpbin anyhow.
We don't need to cater for gcc < 3.1 any longer and can just use
-single_module option unconditionally.
This is simpler and avoids spurious errors about "unknown option" when
using -fsanitize=xxx in LDFLAGS from the script.
Include the version and flavour in the target name, no need to rename anymore.
Add the wxrc symlink to extra uninstall files, not the actual target name.
This currently means macOS 10.11 only, which is only used on Travis CI
and Python 2 installation there is broken anyhow, so this doesn't make
anything worse than it already is.
Don't add -l to libraries already containing it (for example -lpthread).
Change libraries with format libName.so or libName.a to -lName,
configure also uses -l for these libraries. Account for possible invalid
libraries (Name-NOTFOUND) which could happen with imported libraries,
for example OpenGL::OpenGL.

All BCC makefiles were removed as a part of "Remove support for Borland
C++ compiler" PR; however, a few of them sneaked back as a part of the
newly introduced wxWebRequest.
Remove them for good.
Add more functions for manipulating wxImage colours.
Show using them in the same and add new unit tests for them.
This is a squashed commit of branch 'tomay3000/image-lightness'.

No real changes, just use the same _PropertySheetDisplayName element as
the standard style sheets use to show a slightly more user-friendly
label in the Property Sheet manager window in MSVS.
Python package hosting seems to randomly decide which version of the
package to return to pip running under Trusty: in addition to werkzeug
(see last commit), the version of flask has spontaneously changed from
1.0 to 1.2 in the latest build too.
Just hardcode the versions of all dependencies in the last successful
build and hope they keep working for longer than a day.
Crazily, pip installs seem to be non-deterministic as installing httpbin
in https://travis-ci.org/github/wxWidgets/wxWidgets/jobs/765946720
pulled in werkzeug 0.16.1 which works with Python 3.4, but doing it
again tries to use werkzeug 1.x which isn't.
Fix the version explicitly to work around this.
