Make sure that decompression checks for the case that bzip2 returns
...
BZ_OK (meaning more data is expected) but there is no more input data. In
this case, the input file is probably truncated. Generate an exception that
indicates this case when its detected.

This file was schizophrenic when it came to representing sizes. In some
...
cases it represented them as 'unsigned's, which are not enough for 64-bit
hosts. In other cases, it represented them as uint64_t's, which are
inefficient for 32-bit hosts.
This patch unifies all of the sizes to use size_t instead.

After reading in a bc file, trim the resultant buffer down to what we

really need. This reduces 4M of memory consumption reading 176.gcc.

Up the compression threshold to 64K so we avoid it for all but the largest

Tune compression:
...
bzip2: block size 9 -> 5, reduces memory by 400Kbytes, doesn't affect speed
or compression ratio on all but the largest bytecode files (>1MB)
zip: level 9 -> 6, this speeds up compression time by ~30% but only
degrades the compressed size by a few bytes per megabyte. Those few
bytes aren't worth the effort.

Excise the ill-advised RLCOMP compression algorithm and simply leave the
...
previously temporary NULLCOMP implementation that merely copies the data
verbatim without compression. Also, don't warn if there's no compression
library as that is taken care of during configuration time.
