Introduce block header comments and a function naming convention to the
 socket transport implementation.  Provide a debug setting for transports
 that is separate from RPCDBG_XPRT.  Eliminate xprt_default_timeout().

 Provide block comments for exposed interfaces in xprt.c, and eliminate
 the useless obvious comments.

 Convert printk's to dprintk's.

 Test-plan:
 Compile kernel with CONFIG_NFS enabled.
