gf_rsync_weak_checksum:   Calculates a simple 32-bit checksum.
gf_rsync_strong_checksum: Calculates the MD5 checksum.

The strong checksum function makes use of Christophe Devine's
MD5 implementation (adapted from the rsync source code,
version 3.0.6. <http://www.samba.org/ftp/rsync/>).

This is another attempt at fixing build problems on Solaris.
I am told that booster build is disabled on Solaris and I know
that it is disabled on Mac OS X also. Getting it to work
on both these systems is now on my TODO list, mainly
because on both these systems, we can have a glusterfs client
running without requiring FUSE.

This commit changes the booster.conf format from a
simple custom format to that of the /etc/fstab.c

See booster_mount(..) for the mount options supported/required
for LD_PRELOADing booster. I'll write a small help doc soon.

This commit also brings in fstab parsing code into libglusterfs
because Darwin libc only supports reading the hardcoded /etc/fstab.
