Long Range ZIP

This release has been updated to a new zpaq library backend which is faster and now supports three different compression levels. This significantly increases the maximum compression available by lrzip with -L 9. The include file Lrzip.h used by liblrzip is now properly installed into $prefix/include.

lrzcat and lrzuntar have been fixed. lrzuntar will not overwrite existing directories by default now. The update counter will continue to update even when there is nothing being matched (like a file full of zeroes). Numerous optimizations in the rzip stage speeds up the faster compression modes noticeably. Checksumming is done in a separate thread during rzip compression for more compression speed improvements.

A new liblrzip library allows lrzip compression and decompression to be added to other applications. The rzip stage is now faster when files are large enough to require the sliding mmap feature and in unlimited mode. A bug where multiple files being compressed or decompressed from the one command line could have become corrupted was fixed. The modification date of the decompressed file is now set to that of the lrzip
archive. Compilation warnings were fixed. lrztar now works with directories with spaces in their names.

Faster rzip stage through use of selective data access functions. The bash completion script is no longer installed by default, so as to not conflict with distribution bash completion packages. More compilation fixes for non-Linux platforms. Minor cleanups.
