Prior to commit 0e3c1eebb2 nm output depended on the host unsigned
long when printing "negative" symbol values for 32-bit targets.
Commit 0e3c1eebb22 made the output match that seen with a 64-bit host
unsigned long. The fact that nm output changed depending on host is
of course a bug, but it is reasonable to expect 32-bit target output
is only 32 bits. So this patch makes 32-bit target output the same as
it was on 32-bit hosts prior to 0e3c1eebb2.

cc1: all warnings being treated as errors
The warning is bogus of course. xmalloc is guaranteed to return
non-NULL, but apparently this isn't seen in display_utf6. The same
doesn't happen with -m64, maybe due to inlining differences, I haven't
investigated fully. Easily avoided as we hardly need to use sprintf
for a single char, or a two char string.

Many of the fatal errors in nm ought to be recoverable. This patch
downgrades most of them. The ones that are left are most likely due
to memory allocation failures.

Replace the static variables used by nm to cache line number info
with a struct attached to the bfd. Cleaner, and it avoids any concern
that lineno_cache_bfd is somehow left pointing at memory for a closed
bfd and that memory is later reused for another bfd, not that I think
this is possible. Also don't bomb via bfd_fatal on errors getting
the line number info, just omit the line numbers.

Add symcount.

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.

This macro says:

that support name demangling.
This patch addresses the multitude of bug reports about resource exhaustion
in libiberty's name demangling code. It adds a limit to the amount of
recursion that is allowed, before an error is triggered. It also adds a
new demangling option to disable this limit. (The limit is enabled by
default).

This patch performs a run-time test that a shared libbfd.so has been
compiled with the same size bfd_vma as that of apps using the library.
On a 32-bit host it is easily possible to have one libbfd.so compiled
to support 64-bit targets (or configured with --enable-64-bit-bfd)
while another only supports 32-bit targets. The two libraries will
have differently sized bfd_vma types, and if the wrong one is loaded
all sorts of weird behaviour might be seen.

Symbols like *ABS* defined in bfd/section.c:global_syms are not
elf_symbol_type. They can appear on relocs and perhaps other places
in an ELF bfd, so a number of places in nm.c and objdump.c are wrong
to cast an asymbol based on the bfd being ELF. I think we lose
nothing by excluding all section symbols, not just the global_syms.
