20a015e9d3 Fix actions_used_flags not being set when cloning tracerestrict programs. 
This resulted in newly copied or unshared programs not being evaluated.

73b69c5594 Validate type of all instructions, log validation failures at load. 
The validator now checks that the type of conditional instructions
is known.
On a validation failure, the load code now outputs a corrupt savegame
message, with the validation error message and a program dump,
instead of using an assertion.

e2435c7169 Only run trace restrict programs if they contain relevant actions. 
Only run in pathfinder case if deny or penalty are present.
Only run in is safe waiting tile case is reserve through is present.
Presence is determined at program validation time and cached in the
program structure.
Validator now checks for unknown non-conditional instructions.

06a1d7c5c9 Add reserve through action to trace restrict programs. 
This only changes the behaviour of PBS reservations which
would otherwise terminate at a PBS signal.
If the signal restriction sets the reserve through state,
the reservation continues through the signal, and the signal
is set to green.

06cc930e47 Improve insertion and removal of 'or if' conditionals. 
Allow inserting an 'or if' immediately after 'if', 'else if', 'or if'.
Removing an 'or if' no longer removes the associated block.

96ccd9333a Clear PAX stations/signals and traffic lights on load. 
This clears the tracerestrict bit if there are no mappings on a tile.

614b3d8ab5 Trace restrict: Handle removing mapping from refcount 2 empty program. 
Instead of leaving the other mapping pointing to an empty unshared
program, find and delete it.

76707fb72a Change pf penalty restriction value button to preset values and a custom option. 
Preset values are 'small', 'medium' and 'large'.
Change default to 'small' preset.

and the GUI code.

ffed0c194a Add current order (station, waypoint or depot) condition variable. 
Adjust item bit allocations:
* Increase cond flags from 2 bits to 3 bits, for future expansion.
* Use 2 bits remaining in adjacent gap for an auxiliary type field.
  This is used for the type (station, waypoint, etc.) of order tests.
Perform a linear scan of the program pool when deleting a station,
waypoint or depot.

5f1b148cf9 Initial minimal working tracerestrict implementation. 
This is a port of the tracerestrict/routing restrictions feature
from TTDPatch.
At present this implements if tests (train length only),
and pathfinder deny and penalty actions.
This requires the use of YAPF. Note that restrictions are only evaluated
within the YAPF lookahead distance.
