Sun3 native support.

Browse Source 
* config/sun3os3.mh, config/sun3os4.mh (NAT_FILE, NATDEPFILES):
  new macros for native support.
  (XDEPFILES): moved infptrace.o and inftarg.o to NATDEPFILES,
  removed sun3-xdep.o.
* xm-sun3.h (ATTACH_DETACH, FETCH_INFERIOR_REGISTERS): moved to
  nm-sun3.h.
* sun3-xdep.c: removed.  All code is now in sun3-nat.c.
* sun3-nat.c, nm-sun3.h: new files for native support.

* sun3-nat.c, nm-sun3.h: new files for native support.

* dwarfread.c (dbsize): New variable to hold size of dwarf info.
* dwarfread.c (dwarf_build_psymtabs): Rename dbsize parameter to
dbfsize and use it to initialize new local file scope dbsize.
* dwarfread.c (read_ofile_symtab): Initialize dbsize and use it.
* dwarfread.c (basicdieinfo): Use dbsize to check for oversize
DIEs as well as the current check for undersize DIEs. This helps
to gracefully detect and reject corrupted DIE information.

Add `command hooks' and a hook for inferior program stopping.
