Currently it normalizes the path to a string with a single uninitialized
byte. It should instead normalize it to "/".

init is now built as a dynamic executable, so the dynamic linker has to
be able to run in the init process. However, since init is launched so
early, even /dev/* and /proc/* file systems are not mounted and thus
some APIs that rely on the paths do not work. The dynamic linker now
goes alternative path when it is running in the init process.
For example, /proc/self/exe is not read for the init since we always now
the path of the init (/init). Also, arc4random* APIs are not used since
the APIs rely on /dev/urandom. Linker now does not randomize library
loading order and addresses when running in the init process.

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.

Historically we had part of the linker licensed under BSD and
another part under Apache 2 license. This commit makes all the
linker code licensed under BSD license.

resolve_paths function used to print a warning if an input path
was empty. This commit fixes this by explicitly skipping
empty paths during path resolution.
Test: Run adb shell LD_LIBRARY_PATH=: /system/bin/ping
Test: make sure there are no warnings

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)

The permitted_when_isolated_path is a way to white-list
directories not present in search-path. It is ignored for
not isolated namespaces.
