* as.h (relax_substateT): Now defined to be unsigned int.

(relax_stateT): Separate typedef from enum definition.
(enum _relax_state): Reordered for better punctuation.  Added new values
rs_align_code and rs_space.
(lineno, struct lineno_struct): Unused, deleted.

For friendlier assertion-failure messages:
* as.h: No longer include assert.h.
(as_assert): Declare.
(assert): New definition, calls as_assert longer needed.
(__PRETTY_FUNCTION__): Provide default for older versions of gcc.
* messages.c (as_assert): New function.
* gdbinit.in: Put a breakpoint there.
