fix up L2TP text

Rework includes/require. This saves about 4 megabytes.
Simplify get_memory(). Tested on mips/i386

Add propper access control to L2TP pages.

• 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....

• Hide interfaces internals to other code and use the propper interfaces.
  Basically use get_interface*() functions instead of accessing fields like 'ipaddr'/'descr' etc...
• Make get_interfaces_with_gateway less heavyweight by getting information from the configuration stored in config.xml...

Add secret option required on some setups.

Fix typo in function name. This caused the page to break off.

Use the interface API rather than old style interface list building.

Remove all global decalarations regarding pptp/pppoe/l2tp they are no more needed.

Add more L2TP backend code.
