This also allows replacing several literal numbers by named constants
And it should be faster, the function is not speed relevant though as it is
generally only called a few times at the streams start.

This avoids a potential conflict with the equally named function for closing files
It also could reduce confusion in debugger backtraces

The prev_ values were not set after parsing POC.
Increase length of the buffer decoded to parse enough safely.

h264_parser: Initialize the h264dsp context in the parser as well
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This performs the start code search which was previously part of
h264_find_frame_end() - the most CPU intensive part of the function.
By itself, this results in a performance regression:
Before After
Mean StdDev Mean StdDev Change
Overall time 2925.6 26.2 3068.5 31.7 -4.7%
but this can more than be made up for by platform-optimised
implementations of the function.

Each AVStream struct for an H.264 elementary stream actually has two
copies of the H264DSPContext struct (and in fact all the other members
of H264Context as well):
((H264Context *) ((AVStream *)st)->codec->priv_data)->h264dsp
((H264Context *) ((AVStream *)st)->parser->priv_data)->h264dsp
but only the first of these was actually being initialised. This
prevented the addition of platform-specific implementations of
parser-related functions.
