Do not set legacy for now

Do not issue legacy command for time being until a strange error can be tracked down. The ZFS install works OK without it

These are not needed and ends up creating an error. Remove for time beeing

Allow swap spaces and default to 200M

Do not set hostname

chmod a+rx

chmod a+rx

Sync pc-sysinstall with FreeBSD-CURRENT and remove old /PCBSD version. Change installer.php to match new path

Remove update_dns_cache.sh it seems to have been used for hostnames in the filter ruleset which now is handled quite differently.

• Create two new functions lock($subsystem)/unlock() to have more reliable locking using semaphores.
  This function can sleep till the resource is free and can help find not well behaving code.
• Remove most of the config_lock/config_unlock logics on the whole scripts/pages it is an abuse of this....
