Avoid unnecessary internal relocations
Use __attribute__((visibility("hidden"))) for __ncr_file_descriptor to
take advantage of PIC addressing instead of going through the dynamic
linker. Add an internal alias for ncr_global_init() for the same
reason.
Add an internal header file to consolidate the "extern" references in
the process.
