Subject: r152: a quick airport commit ....

added ldbedit, a _really_ useful command

added ldbadd, ldbdel, ldbsearch and ldbmodify to build

solved lots of timezone issues, we now pass the torture tests with
client and server in different zones

fixed several build issues

I know this breaks the no-LDAP build. Wait till I arrive in San Jose for that
fix.
(This used to be commit af34710d4da1841653624fe304b1c8d812c0fdd9)
