Also employ this mechanism to pass $libdir to the runtime library search
path if rpath is enabled. This fixes underlinking of some test binaries
on some systems.
Check the existing flags in the cc/cflags/cppflags/ldflags for
occurrances of -isysroot; if none is found but --sysroot was specified,
set -isysroot to the same value as --sysroot.
This simplifies configuring cross-builds for iOS, if the global
environment variable SDKROOT isn't set.

The rtmp protocol uses nonblocking reads, to poll for incoming
messages from the server while publishing a stream.
Prior to 94599a6de3 and
d13b124eaf, the tls protocol
handled the nonblocking flag, mostly as a side effect from not
using custom IO callbacks for reading from the socket. When custom
IO callbacks were taken into use in
d15eec4d6b, the handling of a nonblocking
socket wasn't necessary for the default blocking mode any longer.
The code was simplified, since it was overlooked that other code
within libavformat actually used the tls protocol in nonblocking mode.
This fixes publishing over rtmps, with the gnutls backend.

mux.c init_muxer() already sets codec_tag correctly in the cases
simplified here.
This also adds the capability to support alternative tags for the
same codec_id.
ff_mp4_obj_type contains the wrong type of tags for
AVOutputFormat.codec_tag. AVOutputFormat.codec_tag is used to
validate AVCodecParameters.codec_tag so needs to be the same
type of tag.
Creates new tag lists for mp4 and ismv. New tag lists support
same list of codecs found in ff_mp4_obj_type. psp uses the same
tag list as mp4 since these both use mp4_get_codec_tag to look up tags.
Properly use the b.eq/b.ge forms instead of the nonstandard forms
(which both gas and newer clang accept though), and expand the
register list that used a range (which the Xcode 6.2 clang, based
on clang 3.5 svn, didn't support).

When targeting the UWP API subset, the LoadLibrary function is not
available (and the fallback, LoadPackagedLibrary, can't be used to
load system DLLs). In these cases, link directly to the functions
in the DLLs instead of trying to load them dynamically at runtime.

The handling of _select dependencies had two issues:
1) extralibs from _select dependencies of a component were not added to
the list of extralibs for that component.
2) extralibs from dependencies were only added to the extralibs of a
component if the component was enabled. This led to incorrect results
if that component was enabled by another component later in the dependency
resolution process. Instead, always generate the full list of component
extralibs for use later in the dependency resolution process.
Also remove a leftover unused variable.
The timeDataSize argument to aacDecoder_DecodeFrame() seems undocumented
and until 2016 04 (203e3f28fbebec7011342017fafc2a0bda0ce530) unused.
After that commit libfdk-aacdec interprets it as size in sample units
and memsets that on error.
FFmpeg as well as others (like GStreamer) did interpret it as size in
bytes.

AVCodecContext::refs is used to control the DPB size to be used by the
encoder. The default value for AVCodecContext::refs as set in
libavcodec/options_table.h is 1.
This patch sets AVCodecContext::refs to 0 for h264_nvenc and hevc_nvenc in
order to let the driver take the decision of the correct DPB size to use in
all cases.

I want to make it non-mandatory to set a mutex in the D3D11 device
context, and replacing it with user callbacks seems like the best
solution. This is preparation for it. Also makes the code slightly more
readable.

The actual hwaccel code will need to access an internal context instead
of avctx->hwaccel_context, so add a new DXVA_CONTEXT() macro, that will
dispatch between the "old" external and the new internal context.
Also, the new API requires a new D3D11 pixfmt, so all places which check
for the pixfmt need to be adjusted. Introduce a ff_dxva2_is_d3d11()
function, which does the check.

So a hwaccel can access avctx->hwaccel in init for whatever reason. This
is for the new d3d hwaccel API. We could create separate entrypoints for
each of the 3 hwaccel types (dxva2, d3d11va, new d3d11va), but this
seems nicer.

To be used with the new d3d11 hwaccel decode API.
With the new hwaccel API, we don't want surfaces to depend on the
decoder (other than the required dimension and format). The old D3D11VA
pixfmt uses ID3D11VideoDecoderOutputView pointers, which include the
decoder configuration, and thus is incompatible with the new hwaccel
API. This patch introduces AV_PIX_FMT_D3D11, which uses ID3D11Texture2D
and an index. It's simpler and compatible with the new hwaccel API.
The introduced hwcontext supports only the new pixfmt.
Frame upload code untested.

Both libraries provide similar functionality and cannot be used together.
When both are enabled one is used and the other ignored arbitrarily. Error
out instead and have the user choose which library to use.
TLS is currently implemented over either OpenSSL or GnuTLS, with more
backends likely to appear in the future. Currently, those backend libraries
are part of the protocol names used during e.g. the configure stage of a
build. Hide those details behind a generically-named declaration for the
TLS protocol to avoid leaking those details into the configuration stage.
If we for some unexplicable reason didn't pick up getaddrinfo
at configure, the default, IPv4-only, fallback should be good enough.
This effectively reverts 6023d84a2b.
