cli : new volume statedump command

2011-09-27T13:45:10+00:00

Changes:
        1. Add a new 'volume statedump' command, that performs statedumps of
        all the bricks in the volume and saves them in a specified location.
        2. Add new server option 'server.statedump-path'.
        3. Remove multiple function definitions in glusterd.h

Statedump Information:

The 'volume statedump' command performs statedumps on all the bricks in
a given volume. The syntax of the command is,
        gluster volume statedump  [type]......

Types include,
        * all
        * mem
        * iobuf
        * callpool
        * priv
        * fd
        * inode
Defaults to 'all' when no type is specified.

The statedump files are created by default in /tmp directory of the
server on which the bricks are present.
This path can be changed by setting the 'server.statedump-path' option.

The statedump files will be named as,
        ..dump

statedump: add more memory accounting related stats

2011-09-22T11:33:40+00:00

* iobuf: add variable to keep count of total number of allocations
* iobuf: include 'purged' and 'filled' arenas also in dump
* mempool: more details added (with a name to tell why mem-pool
  is created)
* memory-accounting: print number of allocs in each type

this would give us much better understanding of the memory
allocation pattern
