f05d024666 ecp5: Use snake case for arch-specific functions 
This makes the difference clearer between the general arch API that
everyone must implement; and helper functions specific to one arch.

d792bce0fb ecp5: Implement IdStringList for all arch object names 
This is a complete implementation of IdStringList for ECP5; excluding
the GUI (which you will have to disable for it to build).

6d23461bcd ecp5: Proof-of-concept using IdStringList for bel names 
This uses the new IdStringList API to store bel names for the ECP5. Note
that other arches and the GUI do not yet build with this
proof-of-concept patch.

getBelByName still uses the old implementation and could be more
efficiently implemented with further development.

75ee2fc4e6 Move RelPtr/RelSlice out of arches into common 
The bba approach seems widely used enough that it's reasonable for this
to become part of common code.

3fc5455ec5 ecp5: Switch from RelPtr to RelSlice 
This replaces RelPtrs and a separate length field with a Rust-style
slice containing both a pointer and a length; with bounds checking
always enforced.

Thus iterating over these structures is both cleaner and safer.

Update CMakeLists.txt 
I believe Prjtrellis has CMAKE define pytrellis as a shared module, not library.
On MacOS, this makes a difference and NextPNR expected ``.dylib``
instead of ``.so``. Things still work on Linux.

b18ea204c2 Remove wire alias API 
It has not actually been implemented in any router for over 2.5 years and causes nothing more than confusion. It can always be added back if it forms part of a future solution; possibly as part of a more general database structure rethink.

f6e30f22f4 CMake: fix path checks in chipdb build scripts. 
`if(NOT DEFINED)` is not appropriate since a variable that contains
`-NOTFOUND` still counts as `DEFINED`. This can cause issues if
configuration fails, writes `-NOTFOUND` to the cache, and is then
restarted.
