WL#1580: --start-datetime, --stop-datetime, --start-position (alias for --position) and --stop-position
options for mysqlbinlog, with a test file.
This enables user to say "recover my database to how it was this morning at 10:30"
(mysqlbinlog "--stop-datetime=2003-07-29 10:30:00").
Using time functions into client/ made me move them out of sql/ into sql-common/.
+ (small) fix for BUG#4507 "mysqlbinlog --read-from-remote-server sometimes
cannot accept 2 binlogs" (that is, on command line).

  Memory was used after it has been alreay freed.
  This led to server crash on FreeBSD.

  Fix assertion failure where ha_myisam::index_next() is called
  without first calling ha_myisam::ha_index_init()

  various fixes (for mysql-test-run at least):
  * accept --no-defaults
  * 4.0 compatible password handling (only it no other argumensts, only if doesn't start with --)
ps_3innodb.test:
  only run ps_3innodb.test if innodb is present
mysql-test-run.sh:
  it's --verbose, not --verbose=1

  Bug #4338  	mysql-test-run fails if compiled with non-latin1 character set.
