Remove all generated files and have them generated when needed. This
build a libgbrpcxdr.la archive with the .o files that gets linked into
the libgbrpc.la archive. 'rpcgen' generates .c code that triggers
warnings for various compilers. This is not something that can easily be
fixed, so add rpc-pragmas.h (like GlusterFS does) to prevent these
warnings.
There are some functions used by gluster-blockd.c that are not part of
the header and were manually added to block.h. Because block.h get
regenerated now, these functions have been added to a new file
block_svc.h.
Note that generated and compiled files land in $(top_builddir). This
directory does not need to be the same as $(top_srcdir).

Till now we had simple makefile for checking dependencies and building.
Using libtoolz will give more control on dependency checks and
flexibility.
This patch also introduce rpm build feature.
Compiling:
$ ./autogen.sh
$ ./configure
$ make -j
$ make install
Building RPMS:
$ make rpms
Running:
$ systemctl start gluster-blockd.service
Using CLI:
$ gluster-block help

This was a hack to implement list and info commands,
now that both list and info reads the metadata from the volume,
we don't need block_exec anymore.

from now We basically have 2 RPC connections,
1. Between gluster block CLI and local gluster-blockd
This connection is basically UNIX/local netid ,listening on
/var/run/gluster-blockd.socket file.
The CLI always Send/Receive the commands to/from the local
gluster-blockd via local rpc.
2. Between gluster-blockd's, i.e local (to cli) gluster-blockd and the
gluster-blockd's running on remote(blockhost)
This is the tcp connection. The rpc requests are listening on 24006
Also from now gluster-blockd is multi threaded (As of now 2 threads)
Lets consider the Create Request to understand what each thread solves
Thread1 (THE CLI THREAD)
* Listening on local RPC
* Generate the GBID (UUID) and create the entry with name GBID in the
given volume with a requested size.
* And Send the Configuration requests to remote hosts,
waits for the replies
(HINt: after this point Read Thread2 and come back)
* Return to CLI.
Thread 2 (THE SERVER THREAD)
* Listens on 24006
* On Receiving an event, read the structure.
* Executes the required "targetcli bla bla bla" command locally
* Fills the command exitcode and the output in the RPC reply structure
and send reply

this patch,
deprecate ssh way of communicating between server nodes/pods
Reason: ssh way is hard to be accepted in container world (Kube).
An another option kubeExec way seems to be a bit weird,
to have uniform way of communication in container and
non container worlds, we prefer RPC.
From now we communicate via RPC, using a static port 24009
Hence, we have two components,
server component -> gluster-blockd (daemon)
client component -> gluster-block (cli)
