lrzip-0.621

As if often the case, once I find time to work on a project, a few releases back to back usually follow. The same happened with lrzip, and here is version 0.621

For fun I compressed all stable linux kernels from 1.0 to 3.19 with lrzip as posted here:

Commemorative linux-1.0-3.19 compressed tarball
This was a 29GB tarball that compressed to 355MB and can be downloaded here:
linux-1.0-3.19.tar.lrz


What's new
- Substantial speed ups for the rzip stage in both regular and unlimited modes.
- Lrzip now supports long command line options.
- Proper support for the various forms of TMPDIR environment variables.
- More unix portability fixes.
- OSX fixes.
- Fixed order of lrzip.conf search.
- Addressed all warnings created with pedantic compiler settings and clang
- Fixes for some stderr messages being swallowed up.
- Fixed being unable to decompress to STDOUT when in a non-writable directory.
- Changed broken liblrzip callback function API to match lrzip proper.


Changelog

* Making the high buffer only one page size is faster for sliding mmap mode
* Fix incompatible log callback in liblrzip
* Use PRId64 instead of lld in fscanf
* Use int64_t for i64
* Fix ISO C warning in lrzip.c
* Fix ISO C warning in lrzip.c

* Brace failure lead to broken dump to stdout
* fflush messages on print_err
* Fix inverse logic
* Honour the proper unix environment variable for temporary directory and then
try variations
