This promotes BFD's struct elf_build_id to the generic struct bfd_build_id,

gdb is updated to use that, and to use the build-id to find symbols for PE files
also.
There is currently no generic way to extract the build-id from an object file,
perhaps an option to objdump to do this might make sense?

LTO output objects have an STT_FILE symbol using the name of the file,
a temporary file. This results in executables that can't be exactly
reproduced, so the file name needs to be dropped. We don't want to
lose all file symbols when linking a mix of lto and non-lto objects as
a file symbol can be used to figure which source file generated a
given local symbol. So lto output objects need to be marked.
I chose to mark lto output objects with a new bfd flag. This flag is
also used to fix a bug in the link-once handling; An object being
loaded after "loading_lto_outputs" is set might be one extracted from
an archive to satisfy new references from lto objects, not an lto
object itself.
The new flag is copied from archive to elements, and the same done
for no_export. This fixes a bug in that --exclude-libs doesn't work
with thin archives. I'm not completely happy with this part of the
patch and may revist this to avoid the hack in
_bfd_look_for_bfd_in_cache.

Linker plugin_maybe_claim is the interface of linker plugin support.
This patch extracts linker plugin_maybe_claim into plugin_object_p and
makes it available to BFD via a new function:
void register_ld_plugin_object_p (const bfd_target *(*) (bfd *));
bfd_plugin_object_p calls plugin_object_p registered by linker first. It
adds an enum bfd_plugin_format field and a pointer to plugin dummy BFD so
that plugin_object_p stores plugin dummy BFD to allow plugin_maybe_claim
to retrieve it later.

Currently, bfd does not compile with -Wunused-value because
the following code:
val = putc ('\n', f);
gets expanded into some code that triggers a warning:
warning: value computed is not used [-Wunused-value]
This is because putc is implemented as a macro...
>#define putc(__x, __p) (((!((__p)->_flag & 0xC000)) && \
> ((__p)->_flag = ((__p)->_flag & 0x3FFF) | 0x8000)),\
> (--(__p)->_cnt < 0 ? \
> __flsbuf((unsigned char) (__x), (__p)) : \
> (int) (*(__p)->_ptr++ = (unsigned char) (__x))))
It's the first part, before the coma operator, which triggers
the unused-value warning.
This patch fixes the issue by simply avoiding the macro and using
fputc instead.
