* alpha-tdep.c:  Gobs of changes (many imported from mips-tdep) to
	improve remote debugging efficiency.  Also fixed problems with
	doing function calls for programs with no entry points.
	* infcmd.c (run_stack_dummy):  Use CALL_DUMMY_ADDRESS instead of
	entry_point_address.
	* inferior.h (PC_IN_CALL_DUMMY):  ditto.
	* mdebugread.c (parse_symbol, parse_procedure, parse_external,
	parse_lines):  Pass section_offsets info to these routines so that
	we can relocate symbol table entries upon readin.
	* (psymtab_to_symtab_1):  Set symtab->primary to tell
	objfile_relocate to do relocations for our symbols.
	* (ecoff_relocate_efi):  New routine to relocate adr field of PDRs
	(which hang off of the symbol table).
	* Use prim_record_minimal_symbols_and_info instead of
	prim_record_minimal_symbols to supply section info to make minimal
	symbol relocations work.
	* minsyms.c (prim_record_minimal_symbols_and_info):  If section is
	-1, try to deduce it from ms_type.
	* objfiles.c (objfile_relocate):  Use ALL_OBJFILE_SYMTABS where
	appropriate.  Handle relocation of MIPS_EFI symbols special. Also,
	add code to relocate objfile->sections data structure.
	* remote.c (get_offsets):  Use new protocol message to acquire
	section offsets from the target.
	* (remote_wait):  Get rid of relocation stuff.  That's all handled
	by objfile_relocate now.
	* config/alpha/alpha-nw.mt (TM_FILE):  Use tm-alphanw.h.
	* config/alpha/tm-alpha.h:  Define CALL_DUMMY_ADDRESS, and
	VM_MIN_ADDRESS.
	* config/alpha/tm-alphanw.h:  DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
