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.

Check for multiplication integer overflow in CHECK_EHDR
The initial fix in r276374 is valid only for 64-bit objects. Revert it and return an error in CHECK_EHDR if the multiplication would overflow.
The original buffer overflow issue was found with the security/afl fuzzer and has upstream elftoolchain ticket 462. The 32-bit object issue with r276374 found by antoine@ during an i386 exp-run.

libelf: Fix cross-endian ELF note file / memory conversion
The namesz and descsz variables need to be used in native endianness. The sizes are in native order after swapping in the file to memory case, and before swapping in the memory to file case.
This issue was identified for r273443, but the change was applied to the wrong case. Revert r273443 to fix the to-memory case, and apply the equivalent change to the to-file case.

Fix the conversion macro for .note sections, broken in the case the ELF file's byte order is not the native byte order. The bug is that the variables holding the name and description size are used (natively) after having been byte-swapped. The fix is to calculate sz from them just prior to byte-swapping.

GCC for PowerPC does not align .note sections to 4 bytes. When running ctfmerge on its objects, libelf asserts as it expects .note sections to be 4-byte aligned. Change that expectation.

Merge from projects/elftoolchain: Upgrade libelf and libdwarf to newer versions from elftoolchain upstream (r2974). Convert ctfconvert to use the APIs from the new libdwarf and make ctfconvert work with Clang 3.4.
__FreeBSD_version is bumped to 1100006.
A list of notable changes:
[libelf]
* The old libelf source code in lib/libelf has been removed. Instead, the new libelf is built from contrib/elftoolchain/libelf. * Manual pages are largely improved. * Internal implementation was refactored and improved for better correctness and portability. * Fixed a few memory leaks. * Extended with extension APIs `elf_open()` and `elf_openmemory()`. These APIs are similar to `elf_begin()` and `elf_memory()` respectively, except that they return an ELF descriptor of kind `ELF_K_NONE` instead of an error if the object being opened could not be parsed. * Implement support for translating sections of type ELF_T_VDEF and ELF_T_VNEED. * Improve `elf_update()` to check that the executable header, the program header table, section contents and the section header table do not overlap, and to ensure that gaps between extents are filled with the fill character specified by `elf_fill()`. * Allow `Elf_Data` descriptors to have types and alignments differing from their containing section. * Remove functionality controlled by `LIBELF_TEST_HOOKS`. * Support processing of BSD-flavor archives. * Add knowledge of section types `SHT_GNU_ATTRIBUTES` and `SHT_GNU_LIBLIST`. * Use elftoolchain style symbol versioning. * Shared library version is bumped.
[libdwarf]
* The old libdwarf source code in lib/libdwarf has been removed. Instead, the new libdwarf is built from contrib/elftoolchain/libdwarf. * Support full DWARF3 and partial DWARF4 parsing. * Support DWARF2 generation. * Support for DWARF line number, call frame, location expression, macro info and address ranges, among other things. * The APIs for the new libdwarf are mostly compatible with the widely used LGPL libdwarf. Some of the incompatible APIs from the old libdwarf are kept as its own extensions. All the APIs are documented. * Use elftoolchain style symbol versioning. * Shared library version is bumped.
[ctfconvert]
* Switch to the APIs from the new libdwarf. * Improve die_mem_offset() so that DW_AT_data_member_location attributes generated by Clang 3.4 can be handled properly. * Make use of DW_AT_byte_size attribute of the member DIE to calculate the bits occupied by the member's type, without actually resolving the type. This way ctfconvert can deal with the case that Clang 3.4 sometimes emits DIE for struct/union member before emitting the DIE for the type of that member.
