In particular, it contains all the riscv64 definitions we need, and lets
us clear up a lot of our existing ELF headers.
The other two BSDs seem to have errors and/or gaps in their riscv64
constants.

Kernel headers coming from:
Git: https://android.googlesource.com/kernel/common/
Branch: android-mainline
Tag: android-mainline-5.18
The file bionic/libc/kernel/uapi/linux/android/binder.h had a bug
in the original 5.18 kernel headers. This was fixed upstream, so
add a comment to the structure but leave the incorrect field the
same as the 5.17 kernel headers.

Until now we've only supported RELR with our own OS-private-use
constants. Add support for the official numbers (while maintaining
support for the historical numbers).
Add tests to ensure we continue to support both indefinitely.
We can't yet flip the build system over to using the official constants
because the old GNU binutils objcopy we still use in most cases (for the
mini-debug section) only supports the historical constants.

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.

This change adds experimental support for SHT_RELR sections, proposed
here: https://groups.google.com/forum/#!topic/generic-abi/bX460iggiKg
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 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

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.

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.

This will make it easier to switch over to a virtual filesystem,
which should drastically improve performance.
This also fixes an issue with warning/error reporting.

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.)

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.
