cli : new volume statedump command

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 <VOLNAME> [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,
        <brick-name>.<pid of brick process>.dump
