commit 2c51604d3adbcc77a25d78ce900f5be4597c2504
Author: Gary Benson <gbenson@redhat.com>
Date:   Wed Jul 23 14:51:26 2014 +0100

    Rationalize "fatal" error handling outside of gdbserver
    
    GDB and gdbserver have functions named "fatal" that are used in
    completely different ways.  In gdbserver "fatal" is used to handle
    critical errors: it differs from "error" in that "fatal" causes
    gdbserver to exit whereas "error" does not.  In GDB "fatal" is used
    to abort the current operation and return to the command level.
    This is implemented by throwing a non-error "RETURN_QUIT" exception.
    
    This commit removes GDB's "fatal" and "vfatal" functions entirely.
    The exception-throwing function "throw_vfatal" is renamed as
    "throw_vquit", and a new convenience function "throw_quit" is added.
    The small number of calls to "fatal" are replaced with calls to
    "throw_quit", making what is happening more obvious.
    
    This commit also modifies GDB's "throw_error" to call "throw_verror"
    rather than calling "throw_it" directly.  This change means the
    assignment of RETURN_ERROR as the exception type now happens in
    precisely one place in GDB rather than two.
