ldlang.h, ldlex.h, ldmain.h, ldmisc.h, ldsym.h, ldver.h, ldwarn.h,
ldwrite.h, relax.h: Replace all uses of EXFUN and PROTO ansi-glue

(keepsyms_file, kept_syms): Declare them.
* ldmain.c (main): Non-fatal errors should still cause non-zero exit status
even with -r.
bfd too #.
* ldexp.c, ldlang.c: now build memory shape tree in obstacks
rather than with raw malloc, makes it easier to track where memory
is going.
