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.

+# This configure script is *not* autoconf-based and has different semantics.
+# It attempts to autodetect all settings and options where possible. It is
+# possible to override autodetection with the --enable-option/--disable-option
+# command line parameters.  --enable-option forces the option on skipping
+# autodetection. Yes, this means that compilation may fail and yes, this is not
+# how autoconf-based configure scripts behave.
+#
+# configure generates a series of configuration files:
+#  - config.h contains #defines that are used in the C code.
+#  - config.mak is included from the Makefiles.
+#
+# If you want to add a new check for $feature, look at the existing checks
+# and try to use helper functions where you can.
+#
+# Furthermore you need to add the variable _feature to the list of default
+# settings and set it to one of yes/no/auto. Also add appropriate
+# --enable-feature/--disable-feature command line options.
+# The results of the check should be written to config.h and config.mak
+# at the end of this script. The variable names used for this should be
+# uniform, i.e. if the option is named 'feature':
+#
+# _feature     : should have a value of yes/no/auto
+# def_feature  : '#define ... 1' or '#undef ...' for conditional compilation
+# _ld_feature  : '-L/path/dir -lfeature' GCC options
