elftoolchain: stop leaving tempfiles on error

Temporary files were not cleaned up, resulting in $TMPDIR or even
the current directory becoming littered with ecp.* files.

This happened with error and even sometimes on success!

When elftoolchain's objcopy (or strip) is rewriting a file in-place,
make it create the temporary file in the same directory as the source
file by default, instead of always using $TMPDIR or /tmp. If creating
that file fails because the directory is not writable, also fallback to
$TMPDIR or /tmp.

This replaces some hand-rolled routines and is substantially faster
since libelftc uses a hash table for lookups and insertions, whereas
elfcopy would perform a linear scan of the table.

Highlights:
- Make sure that only TLS sections are sorted into TLS segment.
- Fixed multiple errors in "Section to Segment mapping".
- Man page updates
- ar improvements
- elfcopy: avoid filter_reloc uninitialized variable for rela
- elfcopy: avoid stripping relocations from static binaries
- readelf: avoid printing directory in front of absolute path
- readelf: add NT_FREEBSD_FEATURE_CTL FreeBSD note type
- test improvements

NOTES:

Some of these changes originated in FreeBSD and simply reduce diffs
between contrib and vendor.

ELF Tool Chain ar is not (currently) used in FreeBSD, and there are
improvements in both FreeBSD and ELF Tool Chain ar that are not in
the other.

Improvements include:

* Add support for reporting and handling a number of new constants in
various tools, including:
* CloudABI OSABI
* DT_TLSDESC_*
* i386, MIPS, SPARC and amd64 relocations

* C++ demangler bug fixes

* Man page updates

* Improved input validation in several tools

This update also reduces diffs against upstream as a number of fixes
included in upstream were previously cherry-picked into FreeBSD.

elfcopy: overhaul of LMA handling

Merge ELF Tool Chain r3434:

Previously, elfcopy defines:

VMA: section virtual address
LMA: PHDR(p_vaddr)

While binutils(libbfd) defines:

VMA: section virtual address and PHDR(p_vaddr).
LMA: PHDR(p_paddr)

For elfcopy, p_paddr is considered not meaningful and is always set
to the same value as p_vaddr.

elfcopy was implemented that way because I thought p_paddr is not
used/meaningful according to the ELF ABI. However it turned out
p_paddr is at least used in some ELF files, e.g. the FreeBSD kernel.

This change made elfcopy treat p_paddr as LMA, same as libbfd.

(However, some VMA/LMA related command line option still need tweaking
to make them compatible with binutils objcopy. This will be improved
later)

Ticket: #524

And typo fixes in r3435 and r3436.

This fixes the Xen kernel build.

The GRP_COMDAT flag was added to elf_common.h in r283110, but it's not
available during the bootstrap build. It is also convenient to be able
to build on older hosts.
