9e4b3675f2 x86inc: Use .rdata instead of .rodata on Windows
The standard section for read-only data on Windows is .rdata. Nasm will
flag non-standard sections as executable by default which isn't ideal.

3a02cbe3fa x86inc: Enable AVX emulation for floating-point pseudo-instructions
There are 32 pseudo-instructions for each floating-point comparison
instruction, but only 8 of them are actually valid in legacy-encoded mode.
The remaining 24 requires the use of VEX-encoded (v-prefixed) instructions
and can therefore be disregarded for this purpose.

b5b4868504 avdevice/decklink: Fix compilation of module on OSX
Clang applies the missing-prototypes warning on C++ files, whereas
gcc only applies it to C.  As a result, the decklink_common.cpp file
fails to build because of missing prototypes in DecklinkDispatch.cpp
(which is #included by decklink_common.cpp).

We don't want to change the actual Blackmagic SDK sources, so
suppress the warning just for that one #include.

5409f065f2 avdevice/decklink: Suppress warning about misuse of struct instead of class
When building with Clang, the following warning is shown:

warning: struct 'IDeckLinkVideoFrame' was previously declared as a
class [-Wmismatched-tags]

The function incorrectly casts IDeckLinkVideoFrame as a struct
instead of a class pointer.

27b9f82e2c hwcontext_d3d11va: implement av_hwdevice_get_hwframe_constraints()
D3D11 has rather fine grained per format capabilities for different uses
that can be queried at runtime. Since we don't know what the user wants
to do with the formats when av_hwdevice_get_hwframe_constraints() is
called, we simply return all formats that have the most basic support.

631c56a8e4 avformat: make avformat_network_init() explicitly optional
It was sort of optional before - if you didn't call it, networking was
initialized on demand, and an ugly warning was logged. Also, the doxygen
comments threatened that it would be made strictly required one day.

Make it explicitly optional. I would prefer to deprecate it fully, but
there might still be legitimate reasons to use this. But the average
user won't need it.

This is needed only for two reasons: to initialize TLS libraries like
OpenSSL and GnuTLS, and winsock.

OpenSSL and GnuTLS were already silently initialized on demand if the
global network init function was not called. They also have various
thread-safety acrobatics, which make concurrent initialization within
libavformat safe. In addition, the libraries are moving towards making
their global init functions safe, which removes all need for central
global init. In particular, GnuTLS 3.5.16 and OpenSSL 1.1.0g have been
found to have safe init functions. In all cases, they use internal
reference counters to avoid that the global uninit functions interfere
with concurrent uses of the library by other API users who called global
init.

winsock should be thread-safe as well, and maintains an internal
reference counter as well.

Since we still support ancient TLS libraries, which do not have this
fixed, and since it's unknown whether winsock and GnuTLS
reinitialization is costly in any way, don't deprecate the libavformat
functions yet.

cbbb206734 hwcontext_vdpau: implement av_hwdevice_get_hwframe_constraints()
In addition, this does not allow creating frames contexts with sw_format
for which no known transfer formats exist. In theory, we should check
whether the chroma format (i.e. the sw_format) is supported at all by
the vdpau driver, but checking for transfer formats has the same effect.

Note that the pre-existing code adds 1 to priv->nb_pix_fmts[i] for
unknown reason, and some checks need to account for that to check for
empty lists. They are not off-by-one errors.

The twoloop coder sounds decent at low bitrates, however at higher bitrates
it sounds worse than the fast coder (which used to be the old twoloop coder
before October 2015) and needs quite a lot more CPU.
Change the default to fast. It has been well tested and has had little changes
over the years so its been confirmed to be quite stable.
Also change its description (not valid for more than a year) and the
documentation.
