* Variadic functions usually cannot be inlined.
* Do not use misleading __always_inline attribute,
and also avoid early clang 7.0 compiler bug.

Test: build and boot aosp*-eng in emulator

__exidx_start and __exidx_end are not actual values to be read, just
symbols placed before and after .ARM.exidx.
The default linker script for ARM static executables includes these
lines:
__exidx_start = .;
.ARM.exidx : { *(.ARM.exidx*) }
__exidx_end = .;

Test: used __gnu_Unwind_Find_exidx in a static executable and showed
non-bogus values
Test: verified that this fixes#593 in the NDK

This commit allows users to create a link without soname filters between
two linker namespaces.
The motivation is to establish one-way shared library isolation. For
example, assume that there are two linker namespaces `default` and
`vndk`. We would like to limit the shared libraries that can be used by
the `default` namespace. In the meanwhile, we would like to allow the
`vndk` namespace to use shared libs from the `default` namespace if the
soname cannot be find in the search path or loaded sonames of the `vndk`
namespace.
shared_libs = %VNDK_CORE_LIBRARIES%
shared_libs += %VNDK_SAMEPROCESS_LIBRARIES%
vndk <-------------------------------------------- default
\_______________________________________________/^
allow_all_shared_libs = true
android_link_namespaces_all_libs() is added to libdl, but it is
versioned as LIBC_PRIVATE. android_link_namespaces_all_libs() is only
for unit tests.

linker namespace of the vendor process can access the shared libs from
the default linker namespace.

These sources are going to be used for the NDK as well, and the NDK
still uses GCC.
This partially reverts commit
4af220cfef. That commit also removed
this symbol from the linker's crtbegin (it has its own). That is
still only built with Clang, so we don't need to revert that part.

We're going to start using the bionic sources for the NDK CRT
objects, so we need to avoid using symbols that weren't around in
early versions of Android. The NDK is currently building the CRT
objects with GCC as well (there were some segfaults that have yet to
be diagnosed), so move `__used` to the GCC compatible location.

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!
Bug: None
Test: Built image for marlin, flashed on device, ran arm and
aarch64 binaries containing '.relr.dyn' sections.

Makes no difference to the benchmarks, but does make the code a bit
more readable.

There were a bunch more unreasonable/incorrect ones, but these ones
seemed legit. Nothing very interesting, though.
