Fixes #4124: Invalid argument '-std=c99' not allowed with 'C++/ObjC++'
C++ files fail to compile. This adds '-std=c++11' to CXX_FLAGS to fix.

Generate the files in a single postprocessing step w/o intermediate files.

This is already taken care of by CLEANSUFFIXES.

If links don't work, fall back to using the full source path as was
previously done.

This should fix build failures with MSVC.

CCFLAGS is equivalent to CPPFLAGS + CFLAGS, and it is already being used
by other make rules like %.i and %.o. Simplifies common.mak.

Previously the full source path was embedded inconsistently in the debug
information between in-tree/out-of-tree builds.

The 'vpath %.inc' becomes necessary for finding
libavfilter/all_channel_layouts.inc in out-of-tree builds.

The full source path is still embedded in the debug information, but
it's now independent of whether building in-tree or out-of-tree.

The biggest improvement of this patch is that gdb now always searches
for the path relative to the source directory. It still also searches
for the full path.
Previously it searched only for the full path in out-of-tree builds,
making the debug information generated by Debian's buildds rather hard
to use.

The versioning facility in the Solaris linker differs from Linux in 3 ways:

1. It does not support globs in linker scripts for
symbol versioning -- this is a GNU extension.

2. The linker argument is '-M', instead of '--version-script'.

3. It is picky about line endings.
Each symbol or directive must be on a line of it's own.

Let's use make_sunver.pl from GCC to generate a version script that works
correctly with the Solaris linker. It's function is to correctly expand the
globs in the original generated version script.

The macro hell sometimes make it difficult to trace the source of
an error, so it is easier to analyze the preprocessed output.

This patch makes this automatical by specifying DBG=1 on the
command line: a file ffmpeg/dir/file.asm gets preprocessed to
builddir/dir/file.dbg.asm, which is then compiled.

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

The gcov/lcov are a common toolchain for visualizing code coverage with
the GNU/Toolchain. The documentation and implementation of this

Many compilers need special flags to compile *.h files as regular
source code, if they will do so at all.  Rather than hoping all
compilers will have such a flag and adding mappings for it, create
wrapper .c files for test building single headers.

This allows using the regular rule for compiling C files without the
need for special flags, and it also provides proper dependency tracking
for these objects.
