Bump major versions of all libraries.

They've accumulated enough new APIs and corresponding deprecated cruft.

This breaks API and ABI.

Replace more FFmpeg references by Libav.

avutil: make aes and sha api public

The functions are already av_ prefixed and sha1 header is already provided.

os: fix OpenBSD/PowerPC compilation

When attempting to re-enable the AltiVec support it was noticed
that we need to undefine _POSIX_C_SOURCE to appease the headers
for ff_get_cpu_flags_ppc() to be able to compile.

Remove unnecessary icc version checks

With unknown attribute warnings disabled, these checks are no

Add a CPU flag for the Atom processor.

The Atom has SSSE3 support, which is useful in many cases, but sometimes the
SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally
faster on other processors supporting SSSE3. This flag allows for selectively...

x86: use raw opcode for xgetbv instruction

This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic. These include clang and some BSD versions.

All AVX code will be written for yasm, where the main assembler
is not involved....

Force inlining of avutil common routines

On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files. This is generally bad, as most of these
functions are smaller inlined than not.

Merge libavcore into libavutil

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody...
