Free linker hash table from bfd_close.
Also tidies numerous error exit paths in various link_hash_table_create
functions that failed to free memory.
include/

Don't call bfd_link_hash_table_free
Freeing the linker hash table is a royal pain. It can't be freed
before the _bfd_write_contents call in bfd_close, because some target
bfd_write_contents functions access the hash table. It can't be freed
after bfd_close either, since bfd_alloc memory holding side data
structures disappears (PR17047). Clearly the only place it can be freed
is actually in bfd_close. This patch doesn't do that, but kills off
the existing means of freeing the hash table via a bfd target xvec call.

Make bfd.link_next field a union
This field of struct bfd is currently only used to chain together
linker input files. This patch prepares to use the field to stash
the linker hash table, which is always created on the linker output
file.
