Codechange: Use consistent name for bay road stops

As of #10494, this is how we describe original dead-end road stops.

Change: Store station blocked/wires/pylons flags in map. (#11337)

This stores three flags in unused map bits, and avoids having to look up
station graphics and custom station specs to determine blocked/wires/pylons
status.

This potentially affects rail pathfinding performance.

Savegame version is not bumped, as the flags can just be updated every
time.

(svn r16909) -Fix [FS#2996]: NewGRF stations would be triggering assertions all over the place when using the more advanced station types.
-Change: make (rail) waypoints sub classes of 'base stations', make buoys waypoints and unify code between them where possible.

(svn r15601) -Fix [FS#2615]: bridges/tunnels don't store tram owner making it possible to remove someone's tram tracks.
-Feature: allow building road stops on road/tram tracks of competitors.

(svn r13234) -Fix: Check/affect town rating when removing/bulldozing town-owned road under drivethrough stops.
-Fix: Reset the 'town-owned-road'-flag when removing and rebuilding road under drivethrough stops.

(svn r12042) -Fix [FS#1676]: Reimplement how rivers and canals are stored in the map, allowing the sea/river/canal status to also be
stored for buoys, docks, locks and depots. All these are now allowed on rivers and removal of them will revert to the
original water type.

(svn r11276) -Codechange: be more consistent with naming of some accessors.
-Fix: make sure canals are never owned by water. Based on a patch by boekabart.

(svn r8833) -Fix

-Codechange: Split MakeRoadStop() into MakeRoadStop() and MakeDriveThroughRoadStop() for more clarity and less possibilities to use it incorrect

(svn r7759) -Merge: makefile rewrite. This merge features:
- A proper ./configure, so everything needs to be configured only once, not for every make.
- Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies.
- A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC.
- Proper support for OSX universal binaries.
- Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files.
- Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files.

Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy.
