Fix problems with infinite recursion when printing a class

	that contains a static instance of the class.
	* cp-valprint.c (dont_print_vb_obstack):  Renamed from
	dont_print_obstack, made static.
	(dont_print_statmem_obstack):  New obstack, controls printing
	of static member classes.
	(_initialize_cp_valprint):  Initialize it.
	(cp_print_static_field):  New function, handles printing of
	static members.
	(cp_print_value_fields):  New parameter dont_print_statmem to
	handle recursive printing of static member classes, use
	cp_print_static_field to handle printing of static members.
	* c-valprint.c (cp_print_value_fields):  Update prototype and
	call to include additional dont_print_statmem parameter.
	* c-valprint.c, f-valprint.c (dont_print_obstack):  Remove unused
	extern declaration.

	* alpha-tdep.c, findvar.c, infptrace.c:  Include <string.h>.

	* config/alpha/tm-alpha.h (FRAME_FIND_SAVED_REGS):  Call
	alpha_find_saved_regs if fi->saved_regs is still NULL.

	* elfread.c (elf_symtab_read):  Ensure that the filename field
	of a minsym is nonempty. Ignore solib trampoline symbols from
	the main symbol table, they might have a bogus value.

	* procfs.c (set_proc_siginfo), config/alpha/alpha-osf2.mh:
	Fix typos in comments.
