* inflow.c (new_tty): Temporarily ignore SIGTTOU when 

disconnecting from controlling terminal, to avoid gdb hanging
	on SVR4.  Fixes bug reported by Oliver Okrongli.
	* procfs.c (PROC_NAME_FMT):  Change format to match default used
	by system, as suggested by Oliver Okrongli.
	* tm-68k.h (FRAME_FIND_SAVED_REGS):  Apply missing parentheses
	bug fix from Brent Townshend (bst%tt@cam.ORG).
	* c-exp.y (nonempty_typelist):  Fix memory overrun bug reported
	by turlais@rechser.total.fr.
	* dwarfread.c (decode_subscr_data):  Fix bug in calculation of
	length of non-zero lowerbound arrays.  Bug fix from Peggy Fieland.
	* objfiles.h (unlink_objfile):  Add prototype.
	* objfiles.c (unlink_objfile):  Add function.
	* objfiles.c (free_objfile):  Call unlink_objfile.
	* objfiles.c (allocate_objfile):  Call unlink_objfile on newly
	remapped objfiles.  Bug reported by hahn@sunshine.labs.tek.com.
	Also, discard old possibly bogus sf struct.
	* symfile.c (symbol_file_add):  Call init_entry_point_info() and
	find_sym_fns() for remapped symbol files, in case of any changes
	since the last mapping.

It is not a bug, or error, to call this function if OBJFILE is not known
to be in the current list. This is done in the case of mapped objfiles,
for example, just to ensure that the mapped objfile doesn't appear twice
in the list. Since the list is threaded, linking in a mapped objfile
twice would create a circular list.
If OBJFILE turns out to be in the list, we zap it's NEXT pointer after
unlinking it, just to ensure that we have completely severed any linkages
