When getting the list of available RPCs from a tool like rpc.py,
aliases often should be hidden.
However, when getting the list of RPCs available
for loading from a JSON config file, aliases should be included.

Add state_mask to each RPC method and state to RPC server, respectively.
State mask of RPC method is set at registration. State of RPC server
is changed according to the state of the SPDK.
When any RPC method is recieved, if the bit of the RPC server is on in
the state mask of the RPC method, it is allowed. Otherwise, it is
rejected.
When any RPC is rejected by state_mask control, the new error code
is returned to describe the error clearly.

Currently if the application exits with some error (i.e., core
dump), the socket file is not removed. So that at next time the
RPC method can not enabled unless user manually removes the
socket file. The error of failing to start RPC is not that
obvious.
This patch introduces a lock for the reuse socket to properly
detect the only usage and handles the above error case particularly.
Refer to https://gavv.github.io/blog/unix-socket-reuse/ for the
details.
For the concern of the sockect file can be shared from different
applications, in the spdk_app_opts struct, it offers a parameter
to assign a specific socket file per application.

RPC is a default feature required for almost all usages,
so enable RPC by default, but with a UNIX domain socket
for security reasons.
-r can now be used from the command line to specify
an alternative RPC listen address from the default
/var/tmp/spdk.sock.
Remove the Enable parameter from the Rpc config section
but still allow specifying an alternative listen address
using the Listen parameter as an alternative to the
command line option. This keeps backward compatibility
for this release for anyone using the configuration file
still.
Remove the Rpc sections from all configuration files
that were using them, except for those that specified
alternate TCP ports for multi-process test cases. We
can fix these later to use an alternate UNIX domain
socket and to use the command line instead.
