ac976ed91e lavr: allocate the resampling buffer with a positive size 
This fixes cases where very few input samples (fewer than needed for one
output sample) are passed to lavr at the beginning.

fdbe18b7b0 tiffdec: use a single strip if RowsPerStrip is 0 
The spec does not specify that 0 is an error condition, and there
are samples which use 0 when the whole image is in one strip.

d4a8a86c68 doc: Libavfilter English cleanup 
This aims to standardize the English used in the libavfilter
documentation, describing the same thing in the same way more often,
and significantly reduce the amount of outright errors, including
run-on sentences and sentence fragments.

617a1a98a6 mp3enc: Properly write bitrate value in XING header 
Instead of using a fixed bitrate_idx, calculate a matching bitrate for
the XING header.

Using a fixed bitrate_idx causes tools such as file(1) and mediainfo(1)
to report wrong bitrate and bitrate mode when using CBR.

f6774f905f mpegvideo: operate with pointers to AVFrames instead of whole structs 
The most interesting parts are initialization in ff_MPV_common_init() and
uninitialization in ff_MPV_common_end().

ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL
checks for Picture.f, because these functions can be called on
uninitialized or partially initialized Pictures.

NULL pointer checks are added to ff_thread_release_buffer() stub function.
