* ldwrite.c: Removed perform_relocation, copy_and_relocate, and
write_norel. All linking is now done via write_relax. Call
ldsym_write before calling write_relax.
* relax.c: Added copyright.
(write_relax): Renamed from write_relaxnorel. Added relocateable
argument. seclet_dump renamed to bfd_seclet_link.
* relax.h: Added copyright.
abs_output_section is what is required.
* ldwrite.c (ldwrite): use malloc to allocate the largest space
used, and pass that down.
* relax.c,relax.h (write_relaxnorel): use the passed malloc area rather
than alloca.
(size_input_section): maintain the delta information.
* ldlang.h: add new field to struct to contain delta info.
* relax.c (relax_section): complain if input not relaxable.
* ldlex.l : add '_', ',' and '$' to chars which can appear at the
start of a filename
to be "-".
* ldsym.c, ldlang.c: remember that size of a section is dependent on
whether or not relaxing has been done.
* ldmain.c: don't open a map file if it doesn't have a name
* relax.c: all the brains have moved into bfd.
* ldwrite.c: ammend comment
