binutils: Fix bugs found by -Wpointer-compare

The MIPS bug was introduced by upstream commit 7403cb630, which failed
to account for the additional indirection introduced and also dropped
one of the checks; change it to the standard "NULL-or-empty" check as
used elsewhere in BFD, which is also what upstream now has.

Improve support for XSAVE with debuggers.
- Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed
to match what Linux does in that 1) it dumps the entire XSAVE area
including the fxsave state, and 2) it stashes a copy of the current
xsave mask in the unused padding between the fxsave state and the
xstate header at the same location used by Linux.
- Teach readelf() to recognize NT_X86_XSTATE notes.
- Change PT_GET/SETXSTATE to take the entire XSAVE state instead of
only the extra portion. This avoids having to always make two
ptrace() calls to get or set the full XSAVE state.
- Add a PT_GET_XSTATE_INFO which returns the length of the current
XSTATE save area (so the size of the buffer needed for PT_GETXSTATE)
and the current XSAVE mask (%xcr0).

Queisce warning about attempting to add char * together and use explicit
array indexing to indicate what is meant to be done

Add an elf note on ARM to store the MACHINE_ARCH an executable was built
for. This is useful for software needing to know which architecture a
binary is built for as arm and armv6 have slight differences meaning only
some binaries build for one will work as expected on the other. It is
expected pkgng will be able to make use of this to simplify the logic to
determine which package ABI to use.

Improve readelf notes output for Linux ELF files

Add four ELF note constants:
- NT_FILE and NT_SIGINFO (core file notes output by recent Linux kernels)
- NT_GNU_ABI_TAG (was incorrectly reported as NT_VERSION)
- NT_GNU_BUILD_ID (used for locating standalone debug files)

Correct ELF note decoding for non-core files

Correct alignment in note output

Remove accidentally cut-and-pasted colons

Handle FreeBSD-specific ELF notes

Add a function to return the specific type, when the note's Name field is
'FreeBSD'.

r249558 added FreeBSD-specific ELF note types that reuse type numbers of
existing generic / Linux types. This caused 'readelf -n' to produce
incorrect output on FreeBSD core files.

Improve compatibility with recent flex from flex.sourceforge.net.

Similar to r239870 and r239872, teach the other binutils tools about the
DW_FORM_flag_present dwarf attribute, so they do not print errors or
warnings on files that contain it. (This attribute can be emitted by
newer versions of clang and gcc.)

Fix a twelve year old bug in readelf: when process_dynamic_segment()
encounters a DT_RUNPATH entry, the global dynamic_info[] array is
overrun, causing some other global variable to be overwritten.

In my testcase, this was the section_headers variable, leading to
segfaults or jemalloc assertions when it was freed later on.

Thanks to Koop Mast for providing samples of a few "bad" .so files.

Merge binutils 2.17.50 to head. This brings a number of improvements to
x86 CPU support, better support for powerpc64, some new directives, and
many other things. Bump __FreeBSD_version, and add a note to UPDATING.

Thanks to the many people that have helped to test this.

Add the ability for GDB to printout the thread name along with other
thread specific informations.

In order to do that, and in order to avoid KBI breakage with existing
infrastructure the following semantic is implemented:
- For live programs, a new member to the PT_LWPINFO is added (pl_tdname)
- For cores, a new ELF note is added (NT_THRMISC) that can be used for
storing thread specific, miscellaneous, informations. Right now it is
just popluated with a thread name.

GDB, then, retrieves the correct informations from the corefile via the
BFD interface, as it groks the ELF notes and create appropriate
pseudo-sections.

With jb's rev 1.2 commit to usr.bin/lorder/lorder.sh we don't depend on
the 4.4BSD's ``nm -o'' behavior.

Previous to 4.3BSD-Reno, ``nm -o'' did not output the .o's filename on a
line by itself. The change occurred between CSRG's nm.c rev 4.8 (1987) and
rev 5.1 (in 1989), which was "new version from Hans Huebner hans@garp.mit.edu,
huebner@db0tui6.BITNET". The Binutils maintainers would rather cater to
a loud boisterous user of 4.3BSD VAXen which has its own native toolchain,
rather than a modern Unix with multiple orders of magnitude more users
and in which Binutils *is* the native toolchain.

Restore traditional behaviour by allowing tabs in strings. In deference
to the new age of internationalisation, I used isblank() instead of a
literal '\t'.

Another directive nit.

Fix the output format of "nm" so that it works properly for FreeBSD's
"lorder" command.

GNU rejected this change because they felt it would be an unacceptable
incompatibility to change the output format at this point -- even
though it was wrong to begin with.
