ITS#7695 Fix ldapsearch regression with CLDAP

Don't try to parse the result of a CLDAP bind request. Since these are
faked, no message is actually returned.

LDAP_CONNECTIONLESS code assumed that the size of an peer address
is equal to or smaller than sizeof (struct sockaddr).

Fix to use struct sockaddr_storage instead which is intended for
this purpose. Use getnameinfo() where appropriate so we don't
assume anything about the contents of struct sockaddr

Don't need to reindex all the attr values if there were no deletes.

Their completion was making slap_graduate_commit_csn() cleanup
their parent op's CSN, thus preventing that CSN from propagating
to any consumers.

Just check normalized name match. Case-changes are allowed.

Don't allow shrinking below minimum size for an already open env.

Do not fail after mdb_page_new() succeeds.

Both were unused and md_name was unmaintained -- except
mdb_cursor_touch(xcursor) would abuse md_name as a key to
touch MAIN_DBI if it could somehow get passed ! DB_DIRTY.

xcursor DBIs were parent DBI+1 for debugging. Instead output
-(parent DBI).  Fixes a crash in mdb_cursor_del0()'s xcursor
tracking, it forgot to subtract 1 for C_SUB cursors.

Leave all lock management to the caller.

Calling app wants to manage its own locking.

MDB_txn.mt_toggle: Use (mt_txnid & 1) instead.
Drop error checks which will be repeated.
mdb_cursor_set(): Turn assert into if/return to match the above.
mdb_cursor_del(): 'flags' are now used as bitflags.

Only named DBs can have DB_STALE, and they do not use MDB_PS_MODIFY.
Replace magic key values with flags.  Drop duplicated comments at
mdb_page_search_root() vs. mdb_page_search(), and rephrase.

Happened since sqlightning #includes mdb.c, midl.c.

The names have caused bugs, "txn" was treated as
the current transaction.

Malloc a page in this txn, not in a parent.

Catch malloc error.
Fix hunt for dirty vs spilled pages: Don't leave x at a deleted pageno.
Cleanup: Factor out variables, squash pages already marked for deletion.

Fix description & code: Also ignore dirty pages hidden by
spilled pages, as they won't merge into our dirty_list.
Update it in mdb_page_flush() instead of mdb_page_spill().

Don't prod sub-pages or pages referring to uninitialized xcursors.

Use fcntl() to set the flag.  Linux open(,O_DIRECT...) can create
the file even on failure, if the filesystem lacks O_DIRECT support.

Set rc=0 when taking the SET_RANGE branch
