ldap_init_fd() tried to handle UDP sockets but was missing
certain key pieces to make it work. Fill in the address and
set the UDP flag correctly.

Allow base entry to be added online with targets
added later. Add SLAP_SERVER_RUNNING flag to note
that main slap_startup has already occurred.

Needed for <resolv.h>, which is needed for BYTE_ORDER.

If updating a page's separator triggers a split in its parent,
we may have missed adjusting the parent's cursor position.

Forgot #include <errno.h>

mdb_txn_begin(): Do not free(mt_free_pgs), it needs mdb_midl_free().
mdb_txn_commit(): Catch commit(child) error.

Do not try to scan me_dbxs in a closed/never-opened MDB_env.
Broken by 7d643d3a
and 151c416b.

No real change.
mdb_cursor_init() checks if it needs mx, so pass it unconditionally.
Set C_ALLOCD for shadow cursors, for clarity. (It was always set as
it should anyway from the origin cursor, which would have C_ALLOCD.)

Unused function when MDB_DEBUG. Unused 'excl' param.

There was little point in returning EINVAL when not: Comparing (A,B)
and (B,A) would claim (A > B && B > A), which could confuse callers.

Catch mdb_cursor_renew(write txn's cursor).  Add flag C_UNTRACK, so
mdb_cursor_close need not peek inside a possibly-freed readonly txn.

Close remaining cursors when committing a write txn. The doc says this
happens, and it avoids cursor tracking when updating mainDB + freeDB.

Rename mdb_cursor_merge() -> mdb_cursors_close() for code reuse,
and add a merge option.  Simplify its loop a bit.

Factor out cleanup of DBIs.

On mdb_env_copy() error: Abort the txn.
On mdb_txn_renew0() error: Release new MDB_NOTLS reader slot.

Redo 8a562f56 so !mt_dbxs indicates
"txn was reset", so mt_numdbs gets one magic value instead of two.

Reset me_dbflags[dbi] when closing DBI, to get rid of MDB_VALID flag.
mdb_env_close(): Re-fix DB-name memleak. DBIs > me_numdbs may exist.

The circular dependency issues appear to have been resolved.
Still, need to watch closely, maybe revert this change if
problems arise.

Due to underfilled branch page. We're in the process of merging/moving
nodes to it because we already know it's underfilled. Took this approach
rather than just removing the assert in mdb_page_search_root, because
that assert may yet catch other situations we don't know about.

(Although, it has been there since the original commit of mdb.c and
has never triggered any other times...)
