* annotate.c (annotate_source, annotate_frame_begin): Issue

`0x' prefix for the pc value, to remain consistent with previous
	GDB versions.

	* blockframe.c (find_pc_partial_function), config/pa/tm-hppa.h:
	Remove Sun shared library transfer hack and
	INHIBIT_SUNSOLIB_TRANSFER_TABLE_HACK, it is obsoleted by the
	mst_solib_trampoline minimal symbols.

	* blockframe.c (inside_main_func):  Check main_func_*pc against
	INVALID_ENTRY_*PC, not zero.
	* symfile.c (init_entry_point_info):  Initialize ei.*pc with
	INVALID_ENTRY_*PC.
	* mipsread.c (mipscoff_symfile_read):  If the entry_file bounds
	are still unknown after processing the partial symbols, then try
	to set them from the minimal symbols.

	* infcmd.c (registers_info):  Error out if selected_frame is NULL.
	* stack.c (return_command):  Select new current frame silently if
	not interactive.

	* mipsread.c (read_alphacoff_dynamic_symtab):  Ignore additional
	DT_MIPS_LOCAL_GOTNO and DT_MIPS_GOTSYM entries.

	* irix5-nat.c (solib_create_inferior_hook):  Call solib_add only
	if auto_solib_add_at_startup is nonzero.
	(_initialize_solib):  Add "set auto-solib-add" command.
	* osfsolib.c (solib_create_inferior_hook):  Call solib_add only
	if auto_solib_add_at_startup is nonzero.
	(_initialize_solib):  Add "set auto-solib-add" command.
