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.
