Handle getting out-of-bounds bits in get_bit (#574)
The binary state is not padded with zeroes, so they must be inferred.

1b54011b68 Use table.copy in mesecons.tablecopy
mesecons.tablecopy didn’t support recursive tables, while Minetest table.copy works well for them.

8743699298 Luacontroller: Fix bugs in 703e6fda, no more functions as keys
Thanks to @ShadowNinja for reporting this
Make sure functions that are keys in tables and functions inside nested tables also get removed when using digiline_send.

703e6fdadb Luacontroller: Restrict digiline messages
Restrict maximum length of messages to 50.000 characters and disable sending functions or table references over the wire. Restrict types of channel variable to string, number or boolean.

The missing length restriction made DoS-like attacks possible by overflowing memory using string concatenation. Thanks to gamemanj for disclosing this issue.

Implement VoxelManipulator-based transactions.
Rather than calling out through the Lua-to-C API for each node that
needs to be read or written, a group of map reads (and optionally
writes) can be grouped into a transaction. Access to map data within the
transaction is provided at high speed by means of VoxelManipulators.
Once the reads and writes are finished, the transaction can be committed
or aborted.

Use VoxelManipulators for get_node_force.
A VoxelManipulator, when asked to read a mapblock, in addition to making
that mapblock available to the caller, also pulls it into the server’s
map cache, thus making get_node calls in the immediate future succeed.

This has the dual advantages that not every mapblock containing a
Mesecons circuit need remain loaded at all times (rather mapblocks can
be loaded on demand as signals are sent), and that the server need not
bother running ABMs and ticking entities within those mapblocks that are
loaded due to Mesecons signalling.

912f17f335 Split wires into their own mod, introduce autoconnect hooks
The update_autoconnect function had to be abstracted away from the
default wires, any kind of wire can now register autoconnect hooks,
which should make having multiple different wire types much easier.

mesecons_mvps, mesecons_receiver and mesecons_random made use of
update_autoconnect, their code was also adapted. This also fixes a
receiver bug: If a receiver was placed with a onstate receptor next
to it (but not the wall lever / button that caused the receiver to
appear) the receiver didn't turn on in the past.

Also move documentation for mesecon wire into mesecons_wire.

cfd4f7c287 Force-load areas with mesecon usage
This is a major speedup for large mesecon machines / structures.
Force-loaded areas are stored in a file to be persistent over server
reboots. By default, areas are unloaded after 10 minutes (600s) without
usage, this can be customized with the mesecon.forceload_timeout
setting. Please turn max_forceloaded_blocks up for better performance.

5be179bf11 Replace mesecon:<some_function> with mesecon.<some_function> for greater
flexibility and because it was never inteded to be OOP in the first
place.

mesecon.receptor_on and mesecon.receptor_off are provided by wrappers
(mesecon:receptor_on/off) for compatibility, but will be removed. Mod
programmers that use mesecons: Please update!

Also, fix microcontroller polluting the global namespace and remove some
deprecated stuff.

194155fff8 Rewrite mesecon wires. This should increase the efficiency and speed of
large machines.

It also makes the wires.lua code easier to understand and more
maintainable. In case any other mod depends on
mesecon:update_autoconnect, please update it to use
mesecon.update_autoconnect. This should also fix some other minor bugs.
Please report bugs if this commit creates new ones.

This commit changes wire looks and removes some unneccesary textures.

f1211f7dae Add ActionQueue priority system
This makes effectors nearer to the source of the action (the receptor) update first.

This defines behaviour for this piston circuit: http://i.imgur.com/9Pp2Mzb.png
And defines, that this memory circuit does not work from this direction: http://i.imgur.com/jJn0aFh.png
But it will work when using the switch from the other side: http://i.imgur.com/nvw0oZB.png

Only if two effectors have the same distance, there is nothing we can do about it, behaviour is not defined.
"Distance" is determined by the stack size of recursions in turnon / turnoff.
Priorities are between 0 (lowest) and 1 (highest).

2d004b19ea First draft of some kind of Action Queue (just like the globalstep queue in to_update), but more flexible and also including delay functionality (mesecon_delayer).
The queue is also saved to a file, so that when restarting mesecons, delayers resume to the state they had when the game shut down. Needs testing.
