Some pthreads symbols might be present in libc (as shown on various *BSD)
but not all of them, leading to false positives.
Check for the most common compiler flags before the plain symbol check
to avoid known pitfalls.

Directly loads AviSynth through LoadLibrary instead of relying on
Video for Windows, and supports using AvxSynth (via dlopen) to
open scripts on Linux and OS X.
Error messages from AviSynth/AvxSynth are now reported through
av_log and exit, rather than the traditional behavior of generating
an error video that the user would need to watch to diagnose.

Include the freetype header, in-directly through a macro, like it
is done in the drawtext filter. Do not break if the header is moved.
Unfortunately the drawtext filter included the file where the include
macros are defined in a wrong way. This is not needed and breaks the
build. Remove that #include line too.

Replace the inline awk script with a Perl script which tracks the
dependencies recursively.
This allows to correctly track dependencies for files including files
with a second level include (for example: ffmpeg-devices.texi ->
devices.texi -> outdevs.texi).
This also adds a dependency on perl for computing the dependencies, which
should not be a problem since perl is already required all the way for
building documentation.
This is a variant of commit 628ceac652
which was reverted due to out-of-tree build failure.

This more closely matches the actual use, also we use plain
strip without these flags for striping
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
This will check if -wN '..@*' is available and fall back on -x if not;
when none are available, do not run strip at all to prevent removing
functions that might be actually needed.

This allows installing into e.g. /usr/lib/ffmpeg and binaries linked
against ffmpeg will pick these .so file while binaries linked against
some fork or different version will pick the libraries in /usr/lib.
There will be still some issues for binaries that (indirectly) end up
depending on multiple variants, but for the simpler cases it should allow
different applications to use different (compatible) variants that
are installed at the same time.

configure: Avoid requiring c99wrap for working around msys path issues
Conflicts:
configure
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Msys is unable to convert unix style absolute paths to windows style
paths when combined with certain multichar MSVC options such as
-Fo<file>. We used to work around this issue by passing them as two
separate parameters separated by a space to c99wrap, which then mapped
them back to the actual parameter format that MSVC uses.
The only paths that actually are an issue are absolute unix style
paths, and the only place such absolute paths are used with the output
arguments (-Fo, -Fe, -Fi, -out:) are for the temp files within configure.
By setting TMPDIR to . for msvc/icl builds, we never need to use
absolute unix style paths for the file output, and we can use the
actual proper form of the file output parameters. This avoids requiring
the c99wrap wrapper for remapping the parameters for cases where the
c99 converter isn't invoked at all (MSVC2013 and ICL).

ICL doesn't return an error on unknown parameters, and will
always pass the symver_gnu_asm test, and since Windows
never has symbol versioning, just always disable it.

On some platforms (such as msys), symlinks are (poorly) emulated
by simply creating a copy of the file.
This means that when building out of tree, the build tree gets
a copy of the original makefile, which can lead to unintuitive
build errors when the original makefile gets updated later.
Instead simply create a stub makefile which includes the real
one.

MSVC does support enough of C99 to work without the converter since
the 2013 version. Try to detect which version of the compiler in
the path needs to run the C99 converter or not. When the converter
is omitted, compilation time is reduced quite drastically.
Prior to this, users could still use --cc="c99conv -noconv cl"
when running MSVC 2013 to achieve the same.
This checks the version number instead of doing a normal compile
test, since this check needs to be done earlier in configure, before
the normal compile test helpers are usable.

configure: Split test_cflags function off from check_cflags
Merged-by: Michael Niedermayer <michaelni@gmx.at>
For some weird reason gcc does not check if the -Wno disabling variants
of warning flags match existing warning flags. Instead it swallows them
silently. That is, unless other warning or error messages are generated,
because then - for some even more bizarre reason - a complaint about the
unknown disable warning flag is issued along with the error or warning
message.
Thus to check for the availability of a warning disabling option, one
needs to check for the enabling variant instead and then add the
disabling variant to CFLAGS.
