cd7f7c12f1 CMake: refactor architecture-specific build system parts. 
Two user-visible changes were made:
* `-DUSE_RUST` is replaced with `-DBUILD_RUST`, by analogy with
  `-DBUILD_PYTHON`
* `-DCOVERAGE` was removed as it doesn't work with either modern GCC
  or Clang

155adc3f5d CMake: rationalize and refactor build system. 
The two main changes, done together in this commit, are:
* Eliminating most instances of `aux_source_directory()`, replacing
  them with explicit file listings; and
* Moving these file listings into respective subdirectories by
  representing respective nextpnr components as interface libraries.

In addition, the GUI CMake script tree was simplified since it had
a lot of unused/redundant code.

The `aux_source_directory()` command is not recommended for use by
CMake itself because it misses dependency changes when adding/removing
files, and consequently causes build failures requiring a clean rebuild.

This commit does not touch anything related to architectures/families,
which are very complex and redundant all on their own.

24e3f8417e json: fix handling of 32-bit parameters 
See YosysHQ/yosys#1671 for rationale.  Also, added some validation
to our parser, so that out-of-range values are reported and the user
knows they should update yosys.

659c4fad56 Change version to git describe and make set-able from outside 
Change version to use git describe instead of git log as this will also work
if tags are present and make the version string set-able from outside as a
parameter to cmake, so that package managers can set this if building outside
of a git working tree.

a0c9a70a5e When choosing between labels for one net, always prefer ports. 
1. Ports are already used in PCF and LPF files, so it is natural
that the developer would use them for constraints as well.

2. Unpredictable (the set of netlabels nextpnr looks at depends on
the optimizations during synthesis) net naming makes it impossible
for code generators like nMigen to reliably apply clock constraints.
