Add mkuzip(8), non-GPL utility to compress filesystem images for use with geom_uzip module. This is based on utility I wrote some 3 years ago for a hack for md(4), which functionally was close to what geom_uzip does today. Since I don't have a time to test that it compiles/works on other arches, stick it to i386 only. Will do it later. Unlike original cloop util, this one embedds FreeBSD-compatible shell code into the generated image, not Linux one. Unfortunately severe space restriction imposed by the CLOOP format doesn't allow to put conditional code which will work both on Linux and FreeBSD. In fact it was quite a challenge to fit necessary FreeBSD code into 127 bytes. ;-) 2004-09-10 20:17:31 +00:00			`# $FreeBSD$`

Improve performance in a few key areas: o Split the compression across several worker threads. By default, "several" matches number of CPUs, capped at 24 for sanity when running on a very big hardwares. Provide option to set that number manually; o Fix bug inherited from the mkulzma (R.I.P) which degraded already slow LZMA compression even further by calling function to release compression state after processing each block. It is neither documented as required nor actually required by the LZMA library. This caused spree of system calls to release memory and then map it again for every block. LZMA compression is more than 2x faster after this change alone; o Record time it takes to do compression and report throughput achieved. o Add simple first-level 256 entry hash table for de-dup code, so it's not becoming a bottleneck at big files. 2016-04-23 07:23:43 +00:00			`SRCS= mkuzip.c mkuz_blockcache.c mkuz_lzma.c mkuz_zlib.c mkuz_conveyor.c \`
o Move logic that determines size of the input image into its own file. That logic has grown quite significantly now; o add a special handling for the snapshot images. Those have some extra headers at the end of the image and we don't need those in the output image really.
