RFC: internal_error() change + abort()

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

Now that we've moved to ISO-C we might as well make use of __LINE__ and
__FILE__.  With that in mind, I'd like to change internal_error()'s
signature to:

	internal_error (const char *file, long line,
			const char *fmt, ...);

with all files updated accordingly.

The second, kind of related change, is to just go through and purge all
but one call to abort() with a call to:

	internal_error (__FILE__, __LINE__, "FIXME: Code was calling abort()");

The abort() calls scattered through out GDB need to eventually be
converted to error() or internal_error() (case by case).  This, somewhat
brutal change, at least stops GDB dumping core on the poor user.

Comments?
