vf_frei0r: adjust error messages
vf_frei0r: prevent a segfault when filter parameters are not set
vf_frei0r: refactor library loading from env variable

strtok_r is not needed any more, so remove it from configure.
mathops: move macro to the only place it is used

This helps in disentangling lavf and lavc too.
put_bits: Remove unused includes

This requires adding includes to other files that relied on these being
included implicitly.
doc: fix a couple of typos in frame.h
vf_frei0r: fix missing end of line character

Error introduced in 61b323ce7c7cdc101eadfd7de2203922b8a39e8d.

configure: enable PIC on s390(x)

The s390 architecture requires shared libraries to be built in PIC mode.
Otherwise applications will get wrong relocations at run-time, leading
to confusing segmentation faults.

avfilter: Add missing emms_c when needed

Arch specific calls should have an emms_c following to keep the cpu
state consistent.

x86: cabac: Use correct #includes to make header compile standalone
arm: hpeldsp: prevent overreads in armv6 asm

Based on a patch by Russel King <rmk+libav@arm.linux.org.uk>

lavfi: use the correct filter context for logging an error.
lavfi: add shuffleplanes filter
FATE: add tests for the shuffleplanes filter
x86: dcadsp: Fix linking with yasm and optimizations disabled

Some optimized functions reference optimized symbols, so the functions
must be explicitly disabled when those symbols are unavailable.
vf_shuffleplanes: fix the type of the mapping indices

They are TYPE_INT AVOptions, so they must be ints
configure: Split x86 SIMD architecture extensions into separate list

This avoids checking inline/external assembly dependencies for x86
extensions that do not play a role in inline/external assembly.
build: Let the SVQ3 decoder depend on the H.264 decoder

The SVQ3 decoder reuses large parts of the H.264 decoder so it
makes no sense to enable the former but not the latter.

Also drop unnecessary h263.o object from SVQ3 decoder object list.
