This can be used to avoid log pollution when e.g. using an x264 unparse function.

The caller may specify any width & height now, rather than having to initialize the x264_param_t's fields directly.
Since it's reasonable to expect GUIs to only provide valid levels (if it doesn't, there's a bug that needs fixing), it's OK to abort when the requested level is not valid.

- H.264 Level 5.2 support.
- Threaded lookahead: improved encoding speed with very fast settings, on systems with 8 processor "threads" or more.
'By default, lookahead threads are 1/6 of regular threads. This isn't exacting,
but it seems to work well for all presets on real systems. With sliced-threads,
it's the same as the number of encoding threads.'
Mini-benchmark:
---------------
2.2 GHz Intel Core i7, 8 processor threads (4 physical cores + 4 virtual cores), Mac OS X 10.7.4. HandBrake's "Normal" preset.
libavcodec decoding threads: 8 / 2 + 1 = 5
x264 encoding threads: 8 * 3 / 2 = 12
x264 lookahead threads: 12 / 6 = 2
Blu-ray, H.264, 1920x1080 -> 1920x800
~48 fps with threaded lookahead, ~42 fps without
DVD, MPEG-2, 720x576 -> 720x576
~224 fps with threaded lookahead, ~192 fps without

param.psz_cqm_file overrides param.i_cqm_preset so you can effectively use cqm in place of cqmfile (but not the opposite).
Thus, add it to the x264_encopt_synonyms array.

H.264 level. Does not modify framerate and resolution but prints warnings when they are incompatible with the requested level.
Exposed to CLI users only via the --h264-level option. GUI support may come later, once we decide how to handle x264 presets/tunes/profiles.
