cfeb28412c ITS#7506 fix prev commit 
The patch unconditionally enabled DHparams, which is a significant
change of behavior. Reverting to previous behavior, which only enables
DH use if a DHparam file was configured.

6f120920d3 ITS#7506 tls_o.c: Fix Diffie-Hellman parameter usage. 
If a DHParamFile or olcDHParamFile is specified, then it will be used,
otherwise a hardcoded 1024 bit parameter will be used. This allows the use of
larger parameters; previously only 512 or 1024 bit parameters would ever be
used.

622d13a32e ITS#7506 tls_g.c: Properly support DHParamFile. 
If a DHParamFile or olcDHParamFile is specified then it will be loaded. This
allows use of DHE/EDH cipher suites which was previously impossible with
GnuTLS.

38b11b1de1 mdb_cursorpages_mark: Mark current txn and no more. 
Ignore parent txn cursors since it is the current txn's dirty_list
which will be flushed. But check the current txn also when clearing,
since cursors can have pages which are dirty in a parent.

Check !mc_xcursor instead of !MDB_DUPSORT.  Equivalent for valid
data, but a bit safer if the sub-DB flags are corrupt.

6741f9c0ef Save freelist using proper mdb_cursor_put(). 
(Restructuring for upcoming mdb_page_spill work.)
mdb_freelist_save() can't just Get() the destination, since
mdb_page_spill() may have put the destination in the read-only map.

TODO: Can this new put() modify the freelist, which would break it? The
final iteration's put() can shorten the node, the rest uses MDB_CURRENT.

We could set P_KEEP on dirty freeDB leaves and ovpages, since they are
all about to be modified.  But the code in this commit must stay anyway,
if mdb should support dropping a 256G DB. I.e. too big for dirty_list.

be47ca7667 ITS#7515 Fix tracking of parent txn's cursors. 
Restore mc_flags and xcursors, they were tracked but not merged.
Simplify: Track parent txn's original cursors after backing them
up, instead of tracking copies and merging them back at commit.

bbb27cde4a bugfix for mdb_cursor_put with MDB_MULTIPLE 
If the variable dkey.mv_size is non-zero, then it means dkey
contains some original data which has to be put back in the
child db, typically when the child db has just been created.

But when using MDB_MULTIPLE, if this variable has not been
reset to zero, we may come back to this section and wrongly
think that there is some original data to be taken care of.

6b56e0fab1 ITS#7453 Fix reset of MDB_NOSYNC/MDB_NOMETASYNC. 
mdb_env_open() with these flags did not open a synchronizing
file descriptor.  Thus disabling them later did not work.

52e3adbdec Renumber MDB_NOSUBDIR. Check mdb_env_open() flags. 
MDB_NOSUBDIR was == MDB_REVERSEKEY. That affected the freelist:
Env flags are stored in mm_flags alias mm_dbs[FREE_DBI].md_flags.

It stays a persistent flag, in case mdb_env_open someday wants
to pick/verify which lockfile to use with the datafile.

Catch bad flags so they will no longer make it into the data file.

c728ebf586 ITS#7428 Use non-blocking IO during SSL Handshake 
If a timeout is set, perform the SSL Handshake using non-blocking IO.  This way
we can timeout if SSL Handshake gets stuck for whatever reason.

This code is currently hidden behind #ifdefs (LDAP_USE_NON_BLOCKING_TLS) and
disabled by default as there seem to be some problems using NON-blocking
I/O during the TLS Handshake when linking against NSS (either a bug in NSS
itself of in tls_m.c, see discussion on -devel)

This patch adds an additional parameter to ldap_int_poll() in order to indicate
if we're waiting in order to perform a read or write operation.

df7ddb6bf4 Add MDB_NOMETASYNC env option. 
Just a trial. This may not make sense if we decide to split the
meta pages into their own separate file, to allow meta traffic to
reside on a separate spindle.

d07779e97b ITS#7313 MozNSS: store certificate object instead of nickname in in ctx 
PEM certificates should not be referenced by nicknames, because the
nicknames are derived from basename of the cerificate file and in
general are not easy-predictable.

The code of Mozilla NSS backend depends on some aspects of PEM module
and tries to guess the nicknames correctly. In some cases the guessing
is wrong.

df1d118de8 ITS#7276 MozNSS: allow CA certdb together with PEM CA bundle file 
Prior to this patch, if TLS_CACERTDIR was set to Mozilla NSS certificate
database and TLS_CACERT was set to a PEM bundle file with CA
certificates, the PEM file content was not loaded.

With this patch and the same settings, OpenLDAP can verify certificates
which are signed by CAs stored both in certdb and PEM bundle file.

4e9926ca97 ITS#7136 MozNSS: store TLS params until the deferred initialization is finished 
Deferred TLS initialization is used with Mozilla NSS. The real
initialization takes place when the TLS context is needed for the first
time. If the initialization parameters were freed immediately after
tlsm_ctx_init was called, they were not available at the time of
deferred initialization which caused segmentation fault.

With this patch, initialization parameters are copied and stored until
the deferred initialization is finished. The parameters are freed
afterwards.

b7057eb61e New sorted-dup subpage support 
Instead of converting directly to a subDB when the first duplicate
item is seen for a key, convert to a subpage instead. Allow the
subpage to grow up to the overflow limit, then convert to a subDB.
This saves a significant amount of space in a typical slapd index
database.

Currently we don't convert back to the smaller form if items are
later deleted. Probably could do that with some hysteresis, e.g.,
convert back from subDB to subpage when the size drops below
(overflow limit/2). Maybe later.
