qsvdec: avoid an infinite loop with no consumed data and no output
This is triggerable with the HEVC decoder. It is unclear yet whether the
bug is in the calling code or the MSDK, but it seems better to check for
this in any case.

configure: force -nologo- when detecting MSVC
The -nologo- option is the inverse of -nologo, reenabling printing the
"logo" version header. This is useful if the compiler actually is a
wrapper that forces -nologo.
this condition breaks reading from the pipe as data_reached variable
have to be set to break while in the asf_read_header just after the Data

hap: Fix slice size computation
A bug was introduced in 977105407cae55876041dddbf4ce0934cdd4cd6c whereby when
frame height wasn't divisible by the number of threads, pixels would be omitted
from the bottom rows during decode.

af_channelmap: properly set the supported output channel layouts
The current code expects query_formats() to be called exactly once, it
will leak if it's not called at all (filter initialized, but never
configured or used) or try to read freed memory if it's called more than
once.

The rationale is that coded_frame was only used to communicate key_frame,
pict_type and quality to the caller, as well as a few other random fields,
in a non predictable, let alone consistent way.
There was agreement that there was no use case for coded_frame, as it is
a full-sized AVFrame container used for just 2-3 int-sized properties,
which shouldn't even belong into the AVCodecContext in the first place.
The appropriate AVPacket flag can be used instead of key_frame, while
quality is exported with the new AVPacketSideData quality factor.
There is no replacement for the other fields as they were unreliable,
mishandled or just not used at all.
This is necessary to preserve the quality information currently exported
with coded_frame. Add the new side data to every encoder that needs it,
and use it in avconv.
Gather all coded_frame allocations and free functions to a single place
Allocating coded_frame is what most encoders do anyway, so it makes
sense to always allocate and free it in a single place. Moreover a lot
of encoders freed the frame with av_freep() instead of the correct API
av_frame_free().
This bring uniformity to encoder behaviour and prevents applications
from erroneusly accessing this field when not allocated. Additionally
this helps isolating encoders that export information with coded_frame,
and heavily simplifies its deprecation.
This change (and the following ones of the same kind) is mainly to
simplify wrapping this section with an #if FF_API block later on.
No functional changes are applied, the fields of the context coded_frame
fields are directly initialized, instead of keeping a reference to the
coded_frame itself.

af_resample: do not touch the timestamps if we are not resampling
This filter currently assumes that the input audio is continuous and
does some timestamps manipulation based on this assumption.
This is unnecessary if we are only converting the channel layout or the
sample format, without resampling. In such a case, just leave the
timestamps as they are.

avconv: split creating and (re-)configuring complex filtergraphs
The current code is less than straightforward due to the fact that
output streams can be created based on filtergraph definitions. This
change should make the code simpler and more readable. It will also be
useful in the future commits.

avconv: create the complex filtergraphs earlier
Since global options are processed before all the other options now, we
do not have to try creating the complex filtergraphs several times
anymore, it is enough to do it once after the input files are opened.

avconv: drop update_sample_fmt()
There is only one decoder left that supports this (libopus, which is not
used by default since we have a native one) and this code goes against
the avconv design, since it propagates information back from the encoder
to decoder.
