Ronald S. Bultje bb6d5411e1 asf: don't seek back on EOF. 
Seeking back on EOF will reset the EOF flag, causing us to re-enter
the loop to find the next marker in the ASF file, thus potentially
causing an infinite loop.

Ronald S. Bultje 6e57a02b9f asf: error out on ridiculously large minpktsize values. 
They cause various issues further down in demuxing.

Ronald S. Bultje 41afac7f7a asf: prevent packet_size_left from going negative if hdrlen > pktlen. 
This prevents failed assertions further down in the packet processing
where we require non-negative values for packet_size_left.

Vladimir Pantelic 69fa23961e asfdec: do not fall back to binary/generic search 
asf_read_seek() inside the asf demuxer already does the
right thing, it tries the index and if that fails it uses
binary search. If binary search is called from outside of asfdec.c
it will fail because the asf code cannot clean up after itself.
Therefore introduce AVFMT_NOBINSEARCH that prevents the seek
code to fallback to binary search and AVFMT_NOGENSEARCH that
prevents the seek code to fallback to generic search.

Uoti Urpala 0bd433a916 asfdec: fix assert failure on invalid files 
Add an extra size validity check in asf_read_frame_header(). Without

Max Horn ca402f32e3 handle malloc failures in ff_get_wav_header 
ff_get_wav_header is reading data from a WAVE file and then uses it
(without validation) to malloc a buffer. It then proceeded to read
data into the buffer, without verifying that the allocation succeeded.

To address this, change ff_get_wav_header to return an error if
allocation failed, and adapted all calling code to handle that error.

get_partial_buffer will be made private later

get_strz is left out becase I want to change it later to return
something useful.
