libavformat/tcp: fix return code for tcp_accept

ff_accept can return AVERROR(ETIMEDOUT) and errno will be 0 (or
undefined), return ret instead and return ff_neterror() in
ff_poll_interrupt instead of AVERROR(errno) to parse WSAGetLastError on

configure: Added require alternative for libmfx to support alternate installation options

Purpose: Added require alternative for libmfx in the case that pkg-config
cannot find libmfx.  On Linux, most people likely get libmfx via
https://github.com/lu-zero/mfx_dispatch , but on Windows, the most
well-known way to get libmfx is via the Intel Media SDK, which
provides a static build of libmfx.lib and also provides the source
code for building libmfx yourself.  If built this way, there are no
pkg-config files to be found.

Comments:

-- configure: Altered enabled libmfx step to use use_pkg_config()
   instead of require_pkg_config(), and, if use_pkg_config() fails, it
   falls back to require().  Also added explanatory comment.  Note
   that the reason that require() is passed -llibmfx as the last
   argument, instead of -lmfx, is the file name for the library
   produced from the Intel Media SDK starts with "libmfx".
   Apparently, the filename for the library produced via
   https://github.com/lu-zero/mfx_dispatch starts with "mfx".

avdevice/decklink: fix MSVC build issues

Purpose: Made minor changes to get the decklink avdevice code to build
using Visual C++.

Notes: Made changes to configure per Hendrik Leppkes's review of first
and second versions of patch.  Also made slight alterations per Marton
Balint's reviews.

Comments:

-- configure: Added if enabled decklink section and setting
   decklink_indev_extralibs and decklink_outdev_extralibs here for
   both mingw and Windows.  Also eliminated the setting of these
   variables in the mingw section earlier in the file.

-- libavdevice/decklink_common.cpp: Switched the order of the include
   of libavformat/internal.h to workaround build issues with Visual
   C++.  See comment in file for more details.

-- libavdevice/decklink_dec.cpp:
a) Rearranged the include of libavformat/internal.h (for reasons as
   described above).
b) Made slight alteration to an argument for call to av_rescale_q() to
   workaround a compiler error with Visual C++.  This appears to only
   be an issue when building C++ files with Visual C++.  See comment
   in code for more details.

-- libavdevice/decklink_enc.cpp: Rearranged the include of
   libavformat/internal.h (for reasons as described above).
