avutil/common: add av_rint64_clip

The rationale for this function is reflected in the documentation for
it, and is copied here:

Clip a double value into the long long amin-amax range.
This function is needed because conversion of floating point to integers when
it does not fit in the integer's representation does not necessarily saturate
correctly (usually converted to a cvttsd2si on x86) which saturates numbers
> INT64_MAX to INT64_MIN. The standard marks such conversions as undefined
behavior, allowing this sort of mathematically bogus conversions. This provides
a safe alternative that is slower obviously but assures safety and better
mathematical behavior.
API:
@param a value to clip
@param amin minimum value of the clip range
@param amax maximum value of the clip range
@return clipped value

Note that a priori if one can guarantee from the calling side that the
double is in range, it is safe to simply do an explicit/implicit cast,
and that will be far faster. However, otherwise this function should be
used.

avutil minor version is bumped.

avformat/async: Fix bug where async could not recover after seek to eof

When async issues its inner seek via ffurl_seek, it treats failures as
EOF being reached. This is not consistent with the behavior of other
protocols (e.g. http, cache) which continue to tolerate reads after
failed seeks, and therefore does not interact correctly with them.

A common pattern where this manifests itself is where avio_seek is
called with pos to be the end-of-file - the http range-request would
fail here, and async would set io_eof_reached to 1. The background
thread would then refuse to read more bytes, and subsequent reads would
only empty the fifo and end in an error.

Presumably the code may have expected subsequent seeks to unset the
io_eof_reached but this is not guaranteed to be true - a subsequent seek
that lands in the AVIOContext's buffer (the fact that the
previously-failed avio_seek leaves the AVIOContext's buffer intact also
suggests that follow-up reads are expected to be tolerated) would not be
issued to the async_seek function, and when that buffer is drained only
async_read calls would follow, leading to the same error just described.

avformat/mov: Add option to ignore chapters during parsing

Chapter-indexing can be expensive since chapters may be interspersed
throughout the entire file and may require many seeks - especially
costly when consuming a video over a remote protocol like http.
Furthermore it is often unnecessary, especially when only trying to get
video info (e.g. via ffprobe).

movenc: Add an API unit test for fragmenting options/calls

Contrary to the normal fate tests that run via avconv, this tests
nontrivial call sequences that are only doable via the API
(mainly for different corner cases when using the muxer for
segmenting).

The test muxes fake packet data (with extradata that looks
enough like proper data to make the file be viewable with e.g.
boxdumper) and checks the hash of the produced files. The test also
verifies that fragments produced via different call sequences remain
identical (to avoid e.g. updating the output hashes and suddenly
having fragments that used to be identical suddenly diverging), for
fragments written with frag_discont and/or delay_moov.

writing the initial moov, to have it behave in the same way.
