The linker currently sets VMA name ".bss" for bss sections in DSOs
loaded by the linker. With this change, the linker now also sets VMA
name for bss sections in the linker itself and the main executable, so
that they don't get left out in various accounting.
Test: Run 'dd' and check its /proc/<pid>/maps.

If one of our threads exits and a new process shows up with the same
tid, we would previously loop until that process exits, leading to
flakiness in tests.
Also fix use of uninitialized memory that happens when threads_count !=
kThreadCount.

This reverts commit 66b5e3ca19.
Reason for revert: Causes installd_dexopt_test to fail. Presumably there is an existing issue which this change is turning into a hard fail, so that needs to be fixed before this can be rolled forwards. See b/139092341.

Anonymous namespace is not created separately. When a regular namespace
is created with ANDROID_NAMESPACE_TYPE_ALSO_USED_AS_ANONYMOUS, that
namespace is used as the anonymous namespace.

RSS is the real measurement by which an allocator should be measured
since RSS is the real memory consumed by the process. PSS is a shared
value.
For memory_replay, PSS and RSS should be the same, so this didn't really
matter in practice, but it's better to use the correct name of RSS.
Also, add a small section about fragmentation.

Before aosp/1086558, this was needed, since we would have
_USING_LIBCXX defined, yet <atomic> was not available, so we'd run
into compiler issues. After that change, we're using
__has_include(<atomic>) so this is no longer an issue.

Linker config now generates ld.config.txt under /dev/linkerconfig from
init. To use this, this change updates linker to pick up
/dev/linkerconfig/ld.config.txt if system property
(sys.linker.use_generated_config) is true.

As of aosp/1086558, stdatomic.h directly checks for the presence of

obsolete.
