Merged-by: Michael Niedermayer <michael@niedermayer.cc>

qsvenc: properly handle asynchronous encoding

Wait for async_depth frames before syncing.

qsvdec: properly handle asynchronous decoding

Wait for async_depth frames before syncing.

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: move the no streams failure to open_output_file()

It is a better place for it, there is no reason to wait until
transcode_init().

avconv: factor out the output stream initialization

avconv: use read_file() for reading the 2pass stats

Also, drop the now unused cmdutils_read_file(). There is no reason to
have two functions doing essentially the same thing.

avconv: move handling the 2pass logfile into avconv_opt

It more logically belongs there.

avconv: set the encoding/decoding_needed flags earlier

This will be useful in the following commits.

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.
