xbps-0.6.0 (2010-06-03):
* Synced libfetch code with NetBSD pkgsrc, updated to 2.31.
* libxbps: improved xbps_get_file_hash() to mmap(2) rather than
read(2) the file we have to process. With mmap'ed files the hash
can be processed 5x faster than before, or even more in some cases.
* libxbps: switch to OpenSSL SHA256 implementation and remove the one
previously used. It's faster and OpenSSL is required for libfetch
so there is not point in using it.
* Added strlcpy() and strlcat() from OpenBSD. Use them if they weren't
found by the configure script on the system.
* Added a configure script that emulates GNU autoconf but simplified,
to simplify customization for build options, flags, etc.
