Move the dxva check after the dependencies have been detected, make sure
the ole32 library exists.
Fixes build on non-Windows.

Build 13 has a crucial fix which makes x265_encode_headers work
as its always been documented.
Previous to this, the check was incorrect.
Also allows for use of the repeat headers flag.

This allows for more elegant dependency and object declarations.

The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we
need to explicitly disable it for these architectures.

Unbreaks windows systems not providing pkgconf files.

Only enable it for CPUs that support it.
This restores the behavior prior to 7a650caf.

Drop the mpegvideo dependency for svq3 in configure.

Group checks into logical groups and sort alphabetically within those groups
unless checks have close coupling. Keep closely coupled checks together.

SPARC is no longer being used in any multimedia-related fields and the
VIS optimizations only represent a maintenance burden.

Previously, it was an implicit dependency through mpegvideo. Change
this, as implicit dependencies can cause all sorts of trouble.

It should work best for debian stable and people not installing the .pc
file.

Should be used only to pass extra flags to pkgconf invocation,
e.g. --static.

Sort lists of components. Add some whitespace where it helps readability.
Consistently use double instead of single quotes around component lists.

The current release of version 1 uses libopenjpeg1.

The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
[....]
}

Not guaranteed to be in nanosecond resolution. On iOS 7 the duration
of one tick is 125/3 ns which is still more than an order of magnitude
better then microseconds.
Replace decicycles with the neutral UNITS. Decicycles is strange but
tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time
is just silly.

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.

This avoids checking inline/external assembly dependencies for x86
extensions that do not play a role in inline/external assembly.
|
|
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.

strtok_r is not needed any more, so remove it from configure.

A threading type might be detected originally, but later disabled
if one of its dependencies is unavailable.
This makes sure that the threading support item in the configure
output is right for setups where w32threads are available but
native atomics aren't.

Almost all of the code is shared so there is little point in
enabling one decoder/encoder without the other.

These codecs compile all of the MJPEG code anyway, so there is little
point in not enabling the MJPEG decoder directly. This also simplifies
the dependency declarations for the MJPEG codec family.
