SQLite for OpenVMS

This is a native port of the SQLite database package to OpenVMS. It delivers the SQLite database to OpenVMS using the following native features:

* Thread support using the tis library.  This allows support for
  multi-threading without having to link against the pthreads RTL.

* Direct file access.  All files access is performed using the $QIO
  system services, rather than the C RTL or even RMS.

* Native locking.  All locking is handled using the OpenVMS distributed
  lock manager, allowing database access to be coordinated across
  cluster nodes (of all architectures).

Despite these OpenVMS-specific improvements the database file maintained by SQLite is still portable to other SQLite-based applications running on other systems.
