linker: simpler encoding for SHT_RELR sections.
This change modifies the encoding used in SHT_RELR sections to a simpler
version that gives better results. This encoding was suggested by Andrew
Grieve and is described in this post on generic-abi@googlegroups.com:
https://groups.google.com/d/msg/generic-abi/bX460iggiKg/Pi9aSwwABgAJ
Bug: None
Test: Built image for marlin, flashed on device, ran arm and
aarch64 binaries containing '.relr.dyn' sections using
the new encoding.

Definitions for the new ELF section type and dynamic array tags, as well
as the encoding used in the new section are all under discussion and are
subject to change. Use with caution!

elf.h: add STN_UNDEF
ELF uses index STN_UNDEF = 0 for undefined symbols. glibc and musl
define this constant in elf.h, and it's needed to build the kernel's
vDSO selftest suite.
Test: Overwrite elf.h in standalone NDK toolchain, then
cd $kernel/tools/testing/selftests/vDSO && \
make CC="aarch64-linux-android-gcc -pie" vdso_test

Restore ELF32_ST_INFO/ELF64_ST_INFO.
Mistakenly removed years ago, along with its genuinely duplicated companions.
This patch also redefines one of those rather than use the Linux uapi header
definition, which leads to signed/unsigned warnings in calling code.

Make all the ELF relocation constants available.
BSD thinks you should only get the relocation constants for your target
architecture, but it's often useful to have them all available at once.
Rearrange the headers to enable that.
Also update the (modified) NetBSD files to CVS HEAD.
Also remove the unused BSDism R_TYPE.

Always include <sys/cdefs.h>.
I made a mistake caught by code review earlier, so let's try to be
safer by default.
This patch also moves all our "forwarding" headers to the guardless
just-include-the-other-thing style that we usually use. (Where we
have a comment explaining where the header comes from, I've kept
that.)

Switch <elf.h> over to linux uapi under the covers.
Remove the linker's reliance on BSD cruft and use the glibc-style
ElfW macro. (Other code too, but the linker contains the majority
of the code that needs to work for Elf32 and Elf64.)
All platforms need dl_iterate_phdr_static, so it doesn't make sense
to have that part of the per-architecture configuration.

libc: add getauxval()
Add support for getauxval(). This method allows a program an easy way
to retrieve information from the kernel auxiliary vector, and will
hopefully replace other clumsy ways of accessing this same information.
This particular function was also added to glibc in glibc 2.16.
See the following URLs for more details.
