updated port options for openssl & sqlite3
fixes for audit & error logging

abstracted some code into new control_sql method
added get_control_dir, get_supervise_dir (reduce duplicated code)
deleted Qmail::check_control (moved logic into qqtool.pl)
changed API of service_dir_get (1 positional arg)
supervise_dir_get: changed API to positional

only a single argument passed
install tcp.smtp during tests, if missing

conf: removed vpopmail_enable_netblocks option (barely used, if at all)
quiet: removed from std_args to dump_audit

the only place it is used
misc code refactoring (reduce and reuse)

lazy load some modules, so 'make test' runs w/o dependencies
added supervise/run file creation for qmail-deliverabled and vpopmaild
moved email_send* tests from Toaster to Setup/Tests.pm
replaced hard coded vpopmail dir with $vpopmail->get_vpop_dir
replaced many hard coded '/var/qmail' paths with $qmail->get_qmail_dir
replace more vpopmail paths wit v->get_vpop_dir
consolidate tcp.smtp functions to setup->tcp_smtp
