Refine Native Library Code: Bulk Permissions, Cleanup DynamicLinker impl. - and fix Android AArch64 BionicDynamicLinker (Bug 1122)

- Bulk Permissions
  ProcAddressTable.reset(..) performs address lookup in one block.
  Now claiming all permissions upfront once, and releasing them afterwards.

- Cleanup DynamicLinker impl.
  Proper top-down impl. of DynamicLinkerImpl,
  handling all security code and validations.

- Fix Android AArch64 BionicDynamicLinker (Bug 1122)
  Dalvik uses diff RTLD_* defines for AArch64!
