Joshua Peraza 2afe6dc210 android/linux: Support modules with shared relros on Android
Add MemoryMap::Iterator to support different strategies for locating
the start of module mappings on Android and Linux.

Beginning with API 21, Bionic provides android_dlopen_ext() which
allows passing a file descriptor with an existing relro segment to the
loader. This means that the mapping containing the dynamic segment
could have a name, device, and inode which are different than the
other mappings for the module.

The revised strategy for Android at API 21+ is to search all mappings
in reverse order from they dynamic array mapping until a module is
parsed with the expected dynamic array address.

Linux and Android 20- continue to select mappings using the device,
inode, and file offsets of the mappings.
