bfd_section_* macros

This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions.  The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections.  Those sections shouldn't be modified
anyway.

The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma.  I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section.  This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.
