Eric Van Hensbergen cb2e87a65d [PATCH] v9fs: fix handling of malformed 9P messages
This patch attempts to do a better job of cleaning up after detecting errors
on the transport.  This should also improve error reporting on broken
connections to servers.

* Huge Nasty Error Table
*
* Plan 9 uses error strings, Unix uses error numbers. This table tries to
* match UNIX strings and Plan 9 strings to unix error numbers. It is used
* to preload the dynamic error table which can also track user-specific error
* strings.
