Archive element size is given by data in the archive, and thus is
subject to attack by fuzzers. The only harm this allows is allocation
of huge amounts of memory, but some systems don't handle that well.
So limit archive element size to archive file size.
* bfdio.c (bfd_get_file_size): Ignore bogus archive element sizes.

We have calls to bfd_get_size when swapping in ELF section headers.
Since object files can have a large number of sections, it's worth
caching the file size rather than making lots of stat system calls.
* bfd.c (struct bfd): Move format and direction to other
bitfields. Add "size".
* bfdio.c (bfd_get_size): Cache size when not writing file.
* opncls.c (bfd_get_debug_link_info_1): Allow for bfd_get_size
returning zero, ie. unknown.
(bfd_get_alt_debug_link_info): Likewise.
* bfd-in2.h: Regenerate.

* bfdio.c (bfd_seek): Optimize away seeks to current position.

Archive element IO is performed on the file of the containing archive,
which leads to the BFD "where" field of archives and their elements
being out of sync with the real file position. (We're talking
traditional archives here, not thin archives.) The old bfd_seek code
recognized this by not attempting to optimize away seeks for
archives. However, there was other code that could return bogus
results. For example, cache.c limits the number of open files by
closing a file and remembering its state once the limit is reached.
If bfd_tell is called on an archive element when the containing
archive is closed, it will return an invalid file pointer.
It's possible to have a valid "where" field for archives by always
using and updating the containing archive BFD. That's what this patch
does. Note that cache.c used to find the containing archive BFD
anyway for the iostream, so we're not really doing extra work, just
transferring it up to the correct abstraction level.
The patch also gets rid of some hacks. bfd_tell was called when
bfd_seek failed, in an attempt to correct "where". That's got to be
papering over another problem, so that code has been removed.
bfd_read also had an "optimiziation" to return early when the number
of bytes was zero, and bfd_seek optimized calls that didn't move the
file pointer. This was covering for a coff_slurp_line_table bug where
IO was attempted on a pe-dll BFD without an iovec.
* bfd.c (struct bfd): Update comment on "where" usage.
* bfdio.c (bfd_bwrite, bfd_stat): Use and update "iovec",
"iostream", and "where" from containing archive file. Return
error on NULL iovec.

LTO plugin support in plugin_maybe_claim wants to close the IR bfd
after replacing it with the recompiled object, but can't do so for
archive elements due to various pointers that access the archive bfd.

element bfds closed.
