drizzled: --help should work in any circumstances

[coldtobi]

Hallo,

drizzled --help should to print the help message and then exit. It should not do other things or do some other funny things.
Especially it should not try to spawn a daemon, which appeareantly it tries...

Example:
# NB: I'm root here.
# lets see what options we have.... The man tells to say drizzled --verbose --help
drizzled --verbose --help
Aborting:"required parameter is missing in 'verbose'. Use --help to get a list of available options. ". Abort was called from drizzled/drizzled.cc:1415 in init_variables_after_daemonizing()
# ok, bug in man.... (I'll report that later)
drizzled --help
Aborting:"drizzled cannot be run as root, use --user to start drizzled up as another user". Abort was called from drizzled/drizzled.cc:578 in check_user()
# mmmh, whats the option to set a user?

drizzled --help --user drizzle
Aborting:"Can't start server, was unable to create PID file: mordor.loewenhoehle.pid". Abort was called from drizzled/drizzled.cc:414 in create_pid_file()
# Why it is try to set the pid file -- all i wanted is the help? (Actually I tried to debug the cannot-open-pid-file issue...)

See attached patch.

The patch tries to emit the help as soon as possible. before parsing the options.
