This library is used by a number of different libraries in the system.
Make it easy for platform libraries to use this library and create
an actual exported include file.
Change the names of the functions to reflect the new name of the library.
Run clang_format on the async_safe_log.cpp file since the formatting is
all over the place.

After the new rebase of Clang, we now support the alloc_size attribute,
so we can remove the warning about switching to alloc_size once Clang
has support.
Also fix an issue where 'false' is returned in a main method.

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.

Depending on how ld.config.txt is configured, there can be multiple
built-in namespaces created by the linker from the beginning of a
process. android_get_exported_namespace is a platform only API for
getting a handle (android_namespace_t*) to one of the built-in namespaces
with given name. The returned namespace can then be given to
android_dlopen_ext in order to explicitly specify the target namespace
where the library is searched and loaded from.
Note that this function only returns 'exported' namespaces created via
ld.config.txt file. In order to export a namespace, the visible property
should be set to true:
namespace.<name>.visible = true
Namespaces are hidden by default. Hidden namespaces and namespaces
that are created programmatically, notably 'classloader-namespace',
aren't returned by this function.
Bug: 36851137
Test: confirmed that namespaces created with ld.config.txt is retrieved.
Test: linker-unit-tests passes

DlExtRelroSharingTest.VerifyMemorySaving verifies whether
android_dlopen_ext(ANDROID_DLEXT_USE_RELRO) really saves memory.
This patch compares Pss of the tested library rather than total
Pss of the process, in case different behavior of dlopen() and
android_dlopen_ext() introduces random Pss usage.

After the new rebase of Clang, we now supports alloc_size attribute, so
we can remove the warning about switching to alloc_size once Clang has
support.
Compiler.setInvocation has changed argument type from raw pointer to
shared pointer. Add version check here so that we can build under either
old rebase or the new rebase.

8-byte watchpoints are not supported on 32-bit kernels (at least on x86,
probably arm as well). 8-byte watchpoints are not required for this
test, so just decrease the size of watchpoints on these architectures.

This needs to be defined as weak because it is also defined in libc.a.
Without this, static executables will have a multiple definition
error.

Fix the list of static functions coming from swab.h to match the
ones exported by glibc.
Force the definition of __HAVE_BUILTIN_BSWAP{16,32,64}__ so the headers
use the builtin.
Add a unit test to guarantee that kernel header updates do not break this.
Test: Built and booted angler.
Test: Built the bionic unit tests for arm, arm64, mips, x86, x86_64.
Test: Ran the new test on angler and glibc.

This change adds two tests for dlopen from temporary files.
1. One Uses memfd_create() can be used to load libraries directly
from memory. This requires relaxing namespace accessibility check
in order to make this work in isolated namespaces.
2. Another checks that open with O_TMPFILE works.

We know what "3" and "40" are, but most folks not on our team don't.
I don't think we need to support all the weird values, because only the
supported architectures actually occur in practice.
