This significantly reduces the amount of stack space needed and
also permits to simply copy the rice context again without speed
penalty

Some files benefit by about 0.3% from this, and speedwise its ok
other files do not benefit and encode to the same size

Should improve cache usage and reduces stack usage.
Also reduces number of copies in case many levels
have the same number of bits.

It now does 12 samples per iteration, up from 4.
From 1.8 to 3.2 times faster again. 3.6 to 5.7 times faster overall.
Runtime is reduced by a further 2 to 18%. Overall runtime reduced by
4 to 50%.
Same conditions as before apply.

From 1.8 to 2.4 times faster. Runtime is reduced by 2 to 39%. The
speed-up generally increases with compression_level.
This lpc encoder is not used with levels < 3 so it provides no speed-up
in these cases.

The compatibility wrapers are left as they likely sre still
in wide use. They will be removed when they break or otherwise
cause work without an volunteer being available.

This fixes use of uninitialized values when the FLAC encoder uses the
2-level, 4-level, and 8-level search methods. Fixes failure of the
fate-flac-24-comp-8 test when run using valgrind.
