Fixes for pty handling in gdb-mi.el and process.c.
* lisp/progmodes/gdb-mi.el (gdb): Revert 2012-04-19 change. (gdb-inferior-io--init-proc): New function. (gdb-init-1): Use it. (gdb-inferior-io-sentinel): New sentinel for the gdb-inferior pty, responsible for allocating a new pty and hooking it to gdb when the old pty gets an EIO due to process exit. (gdb-delchar-or-quit): New command. Bind it in gdb-mi buffers. (gdb-tooltip-print): Don't use obsolete tooltip-use-echo-area. (gdb-inferior-io--maybe-delete-pty): Move into gdb-reset. * src/process.c (wait_reading_process_output): If EIO occurs on a pty, set the status to "failed" and ensure that sentinel is run. * doc/lispref/processes.texi (Asynchronous Processes): Mention nil argument to start-process.
