r8643: - make lp_configfile() work again

- get rid of redundeny dyn_CONFIGFILE argument to lp_load()

- fixed provisioning to work with completely pristine install,
  creating an initial smb.conf is none is present

- added lp.set() and lp.reload() to loadparm ejs object interface
(This used to be commit c2691ef7126ddcee5f95970b78759b40a049d0a7)
