open(2) can be used to open directories; use stat to
check that the file exists and is a regular file.

Change-Id: Ia944db2f2f779a87ea01dd41dcd171e59c9bef01
This patch enables absolute path translation to instrumented library
when linker_asan is in use.
Test: adb shell cat /proc/<rlid pid>/maps | grep libril-qc-qmi-1.so
check that it is mapped from /data/vendor/lib64 and not /vendor/lib64

(cherry picked from commit 5aa67675f8)
Give a compile time diagnostic when the nullptr sentinel is missing
from an execl family call, instead of just pulling arbitrary values.

Test: Built bullhead
Hiding our legacy cruft seemed like a good idea, but in practice it will only
mean worse interoperability.
Plus we got it wrong, as the recent `putw` example showed.

Improve sanity-checks of elf-file by adding alignment check
of mapped sections and section headers.

(cherry picked from commit 7e2d49ae3e)
Move soinfo and globals out of linker.cpp to
separate files.
Breaking up huge linker.cpp into smaller peaces
in order to make it easier to extract part of the
code that belongs to libdl.so and remove parts of
the code that do not belong to linker
(refactoring part 2 of many)

This assumes that it's more likely we're unlinking a file than a directory,
though even if that's not true, as long as a failed unlink(2) is cheaper
than a successful lstat(2) -- which seems likely since there's no data to
copy -- we still win.

Bionic stdatomic.h is also used for the host (via a copy in
prebuilts/clang). Revert to guarding the include of uchar.h based on
__STDC_VERSION__, so it is included only when needed.

Test: bionic tests on host and Angler. Confirmed failures I am
seeing are KIs.
* changes:
Add version information for legacy inlines.
versioner: remove unnecessary kernel/common symlink.
versioner: add symlink for kernel/android/uapi.
With the introduction of new tags for ndk_library, we'll have a lot
of tags that aren't architecture tags. If we have something tagged
`introduced=21`, it should be in all architectures.

The target was moved by commit 5956b4e, but none of the headers
contained were actually necessary to compile any bionic headers.

The android-only kernel headers were moved to their own directory by
commit d6e8b8c. Add a new symlink to match.

With this change (and all the others below it in the stack), the only
difference between the arm android-9 libc.so in r13-beta1 and the one
we are now generating is the addition of LIBC_N and LIBC_O versions.
Test: make ndk, readelf stub libc.so to check symbol exists

These functions were erroneously released in LIBC_PRIVATE for M, but
in fact need to be public. Since we need to be able to load them on M
even if they were built for a lower platform (and M needs to load on
newer platforms), we need to unversion them.
