56b8d10676 configure: Refactor setting of feature test macro _XOPEN_SOURCE
Some C libraries, eg glibc, uclibc, and musl, uses feature test macros
to expose definitions conforming to the standards ISO C, POSIX and
extensions. According to which feature test macros are defined by the
user or the compiler, a header file, eg <features.h>, used by these
libraries internally defines various other macros.

glibc and uclibc also defines release test macros, eg __GLIBC__ and
__UCLIBC__ in <features.h>. musl does not have (and does not want) a
macro __MUSL__. Therefore it is not possible to check for the musl
library.

However, building FFmpeg with musl needs the feature test macro
_XOPEN_SOURCE=600 to be defined.

749b1f1359 configure: add --enable-rpath
This option facilitates testing shared libarary builds: for instance
fate builders do no longer need to set LD_LIBRARY_PATH as the binaries will
get the right search paths hardcoded into their executable file.

This option is only meant to be used for testing purposes: The installed
libraries must not move around in the file system, and doing so will
cause a lot of subtle problems. For more information why using RPATH is
dangerous, please refer to

b0352b1997 avcodec: export motion vectors in frame side data on demand
The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.

It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.

This commit also includes an example exporting them in a CSV stream.

08b94f160a configure: Don't pass MSVC compiler options -M[TD] to armasm
The -MD option (for enabling a dynamically linked crt) gets interpreted
as a cpp option for generating dependency information (into a file named
'-.d', when preprocessing to a pipe). We shouldn't be passing
any and all C compiler flags to armasm (which is a plain assembler,
only with cpp bolted on via gas-preprocessor), but these are the
main conflicting ones.
