These changes are required to make GlusterFS compile on MacOSX (10.5).
Currently glusterfs server component alone will work over Mac, and it has
to be built with following options to ./configure.
"bash$ ./configure --disable-fuse-client --disable-fusermount "

with this without bumping protocol version.

* option to provide 'eliminate-pattern' so those files matching
won't be kept in trash. Eg:
option eliminate-pattern *.out|*~
* option to give 'maximum' file size to keep in trash, ie, when a
20GB file is deleted, it won't be kept in trash if max file size
given is 1GB. Eg:
option max-trashable-file-size 1GB

lookup on same path if one is in progress.
- If current lookup (2) does not wait for completion of the lookup (1) which
is in progress, there can be a race condition where (2) completes ahead of
(1) and resuming all the waiting operations in the queue. When (1) returns,
the original operation (eg., stat, chmod etc) might've already unwound and
hence the frame would've been destroyed.

Changes in libglusterfs/rbthash:
rbthash_table_init() now takes a mem-pool argument.
The mem-pool argument would be mutually exclusive to expected_entries.
If expected_entries is provided, mem-pool would be ignored and vice-versa.
Changes in io-cache:
1) Moved rbthash creation to readv.
2) rbthash makes use of 1 rbt instead of 4096
3) A global mem-pool is being used in place of a mem-pool per rbt.
