* commit '993977032a0adb47eb70e7fef6ce0d5370027e83':
xan: Use bytestream2 to limit reading to within the buffer
pcx: Consume the whole packet if giving up due to missing palette
pngdec: Stop trying to decode once inflate returns Z_STREAM_END
mov: Make sure the read sample count is nonnegative
bfi: Add some very basic sanity checks for input packet sizes

If the input buffer contains more data after the deflate stream,
the loop previously left running infinitely, with inflate returning
Z_STREAM_END.

Wrong bit depth can lead to invalid rowsize values, which crashes the
decoder further down.

I am not sure these new values are correct, not am I sure
the semantics are a good idea since we do not seem to make any
use of them but they caused a lot of confusion, but this
seems to make things closer to matching the documentation.

Ignore color_type information for setting the monoblack pixel format,
only rely on bit_depth.
In particular: fix Test_1bpp_grayscale.png from issue #172.
This may work fine for some broken encoder, and not for others.
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

None of these symbols should be accessed directly, so declare them as
