elfcopy: Use libelftc's string table routines to build .shstrtab.

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.

elfcopy: copy raw (untranslated) contents to binary output

Previously elfcopy used elf_getdata to obtain data from ELF sections
being copied to binary output, but elf_getdata returns data that has
been translated - that is, data is in host byte order. When the host and
target differ in endianness (e.g., converting a big-endian MIPS ELF
object to binary on an x86 host) this resulted in byte-swapped data in
certain sections such as .dynamic.

Instead use elf_rawdata to keep data in the original, target endianness.

Update to ELF Tool Chain r3475

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: include extension but replace . when converting from binary

The change in r291958 was not consistent with GNU objcopy. The start,
end and size symbols created for ELF objects converted from binary need
to include the full filename including the extension, but with the
periods replaced with underscores.

elfcopy: exclude extension when converting from binary

When converting from binary to ELF, elfcopy creates symbols
_binary_<filename>_start_, _binary_<filename>_end, and
_binary_<filename>_size. For compatibility with GNU objcopy (and to
produce sensible symbol names) the extension must be stripped off.
