[Patch] Mechanism for board files to set default remotetimeout

[Sterling Augustine <saugustine@google.com>]

[-- Attachment #1: Type: text/plain, Size: 495 bytes --]

The enclosed simple patch adds and demonstrates a new mechanism for a
board file to declare a default remotetimeout. It follows a similar
mechanism as set height 0.

This is useful if the board has high latency for internal gdb
commands, as remote-stdio-gdbserver.exp does.

OK for trunk?

	* lib/gdb.exp (default_gdb_start): Use new global gdb_remotetimeout.
	* boards/remote-stdio-gdbserver.exp: Set global gdb_remotetimeout.
