Built on top of the MetadataObjLib, this library aims to
provide functions for each METADATA_ID to:
- Generate new Metadata on the fly: the caller provides
  minimal information for a METADATA_ID, and the library
  generates the missing information.
- Validate all the Metadata objects for a METADATA_ID.
  For instance, _UID must be unique for a _HID/_CID/EISAID.

This patch also adds support for generation/validation of:
- UIDs:
For each EISAID or NameId, UIDs must be unique. The generation
if UIDs is done by a per-EISAID/NameId incrementing counter.
The validation of the Metadata consists in checking for the
uniqueness of the UID per EISAID/NameId.

- ProximityDomains:
Proximity Domain Ids are generated by a counter, starting
from 0.
The validation of the Metadata consists in checking for
the uniqueness of the proximity domain Ids.
