7710ff187b api: close private namespace when unloading DLL
Prior, people making calls to LoadLibrary/FreeLibrary would experience
a failure to create or open adapters, because the private namespace was
already loaded into the process and not cleaned up on DLL detachment.
While this pattern is probably a misuse of the library, we should still
support cleaning that up. This commit makes the right calls to free the
boundary descriptor and close the private namespace. It does not,
however, destroy the private namespace using the flag on the second
parameter, in case of races with other processes.

We must not use the process heap, as it is changeable. Client may change
it causing our HeapFree() to use wrong heap.
