0b882b4009 Fix crash in MLP decoder due to integer overflow.
Probably only DoS, init_get_bits sets buffer to NULL, thus causing a
NULL-dereference directly after.

30b6147521 Use av_get_bits_per_pixel() for computing the bits per pixel of the
source and destination format, cache those values in the newly added
SwsContext:srcFormatBpp and SwsContext:dstFormatBpp fields, and remove
the fmt_depth() function.

0c32e19d58 Move +52 from the loop filter to the alpha/beta offsets in the context.
This should fix a segfault, also it might be faster on systems where the
+52 wasnt free.

87ac0c0a39 Use AVPALETTE_COUNT instead of hard-coding 256.
This is consistent with other codecs and will also avoid a crash on the
memcpy to data[1] if AVPALETTE_SIZE ever increases.
