1. Cleanup for #inclusivefixit. (whitelisted -> allowed_libs)
2. Support the old term for backwards compatibility. (Also update test.)
3. Fix the formatting errors found by clang-format.

When a library is present in a namespace via the secondary_namespaces
list (i.e. the executable, LD_PRELOAD, DF_1_GLOBAL, or
android_create_namespace inheritance), then we want to search that
library's symbols, but not the symbols of its dependencies. Otherwise,
we want to search the dependencies to handle cross-NS dependency.

In order to enable no-vendor-variant VNDK, we need a way to restrict a
namespace to only a list of whitelisted libraries. We add a new
"whitelisted" property for this. If the property is not set, all
libraries in the search paths are available in a namespace. If the
property is set, only the libraries named are available.
Bug: 119423884
Test: Boot with no-vendor-variant VNDK enabled using the new property.

Explicitly say "warning" for warnings, explicitly say what action
we're going to take (such as "(ignoring)"), always provide a link to
our documentation when there is one, explicitly say what API level the
behavior changes at, and explicitly say why we're allowing the misbehavior
for now.

Test: ran tests, looked at logcat

With ld.config.txt, we now have multiple built-in namespaces other than
the default namespace. Libs (and their dependents) listed in LD_PRELOAD
must be visible to those additional namespaces as well.
This also adds a debugging only feature: path to the linker config file
can be customized via LD_CONFIG_FILE environment variable. This works
only for debuggable builds.

Test: 1. ./external/compiler-rt/lib/asan/scripts/asan_device_setup --lib
prebuilts/clang/host/linux-x86/clang-stable/lib64/clang/5.0/lib/linux
2. enable talkback shortcut
3. in the home screen, hold vol-up/down together
4. device does not reboots and talkback shortcut is toggled
Test: bionic-unit-tests and linker-unit-tests successful

Skip the check for accessibility in the case soinfo
does not have primary/secondary namespaces associated
with them.

Test: start an app from http://b/37191433 make sure it does not crash on lunch

Avoid constructing vector and walking all the parents of a soinfo
to check if it is accessible. The most likely scenario that the
very first check returns true.

This commit updates interface of libdl.c.
1. android_init_namespaces is replaces with android_init_anonymous_namespace
2. added 2 arguments to android_create_namespace to specify linked namespace
and the list of shared libraries sonames.
3. symbol lookup does not get past boundary libraries (added check and test for it).

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 1 of many)
