switch the build system to waf
This commit adds a new build system based on waf. configure and Makefile are deprecated effective immediately and someday in the future they will be removed (they are still available by running ./old-configure). You can find how the choice for waf came to be in `DOCS/waf-buildsystem.rst`. TL;DR: we couldn't get the same level of abstraction and customization with other build systems we tried (CMake and autotools). For guidance on how to build the software now, take a look at README.md and the cross compilation guide. CREDITS: This is a squash of ~250 commits. Some of them are not by me, so here is the deserved attribution: - @wm4 contributed some Windows fixes, renamed configure to old-configure and contributed to the bootstrap script. Also, GNU/Linux testing. - @lachs0r contributed some Windows fixes and the bootstrap script. - @Nikoli contributed a lot of testing and discovered many bugs. - @CrimsonVoid contributed changes to the bootstrap script.
