Bug was caused by postalAddressNormalize sending 0-length values
to UTF8StringNormalize.

Well, just like in back-bdb in 2005, it only slowed things down
on larger LDIFs.

Sub-pages need room to grow...

NULL out env->pghead before writing it, so that its pages can't be used
to satisfy the write.

Only for DUPFIXED DBs. Still could do better.

Missed a MDB_RESERVE case

When putting a record, just make space for the data, don't copy it.
(Not compatible with MDB_DUPSORT, since the actual data is needed
to determine the insert location.)

Skip the original cursor that made the change

PEM nss is not thread safe when establishing the initial connection
using SSL_ForceHandshake.  Create a new mutex - tlsm_pem_mutex - to
protect this function call.
The call to SSL_ConfigServerSessionIDCache() is not thread-safe - move it
to the init section and protect it with the init mutex.

Only worry if consumer has newer state for our SID. Fixes breakage
caused by ITS#6606.

Consumer should never get NO_SUCH_OBJECT for an Add to the underlying DB
during Persist phase.

Must not let the underlying DB generate its own.

Create the data file using exactly the given pathname, and
the lock file using a suffix on the data file name.

Nested txn stuff which we don't use.

For any change to a page or node, update all other cursors pointing
at the same page (or node). Cursors are now stored in a linked list
off their owning transaction. Cursors are all closed when the transaction
ends. Cursors in parent transactions are updated when their child
transaction commits.
