* bfd-in.h: New macros bfd_asymbol_bfd and bfd_asymbol_flavour;

Browse source 
perhaps we can later remove the the_bfd field from each symbol.
	* syms.c (struct symbol_cache_entry):  Remove unused field
	app_data.  Add comment noting that the_bfd is almost redundant,
	but not quite.
	* aoutx.h, coff-a29k.c, coff-i386.c, coff-i960.c, coffcode.h:
	Use new macros bfd_asymbol_bfd and bfd_asymbol_flavour.
	* hppa.c (fill_spaces):  Make slightly more rebust.
	* configure.in:  Allow std-host as the "default" host.

* hosts/std-host.h: New file. Attempt at a generic/default
set of definitions, to discourage porting to new hosts by copying.
* hosts/news.h: Removed.
* hosts/sparc.h: Use std-host.h.
