(struct xcoff_link_hash_table): Add descriptor_section and
special_sections fields.
(_bfd_xcoff_bfd_link_hash_table_create): Initialize new fields.
(xcoff_link_add_symbols): Set linkage section alignment. Create
descriptor section. Check for magic symbol names (_text, etc.),

(bfd_xcoff_export_symbol): Check whether the symbol might be a
function descriptor, and mark it if it is.

parameter, and fill it in. Allocate space for the descriptor
section.

exported symbol.

necessary.

rather than normal symbol table.

itself.

undefined symbol when creating a shared library.

global linkage code for a call to an undefined symbol.
Added some new interfaces, and a new entry in the target vector. Under the new
interfaces, mmap will be used if available, otherwise malloc/seek/read, as
before. Old interfaces all still intact.
Most configurations (including all used by "--enable-targets=all") simply
changed to call the default routine for that entry in the target vector. I
might've missed some targets only included in special configurations.
Support for a.out symbol and string table reading now goes through new
interfaces, and will use mmap when available.
Linker hooks (e.g., avoiding reallocation under malloc) not ready yet.
to o. Clobber and restore the list of new csects around the call
to _bfd_generic_link_add_one_symbol, in case it wants to report a
linker error and the linker wants to read the symbol table. Reset
the line number count of a real section even if it has no relocs.
(_bfd_xcoff_bfd_final_link): If shared, set the DYNAMIC flag.
