abort() to internal_error()

[Andrew Cagney <ac131313@cygnus.com>]

Hello,

KevinB's kindly cooked up a script that will replace all instances of:

	abort ();

with

	internal_error (__FILE__, __LINE__, "function calls abort ()");

Applying and committing this script will signify the end of a very long
campain I've been waging with GDB - to significantly reduce the
likelhood that GDB dumps core.

From memory, this has been discussed several times before (and is listed
in the TODO file).  The only problem I can think of is the message. 
However, if you think about it:

	(gdb) pwd
	internal_error: /a/b/c/d/foo.c:47: function calls abort ()
	....

is still infinatly better than something like

	(gdb) pwd
	Program received SIGXYZZY, core dumped
	$

so I think is good enough,

comments?

	Andrew
