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).

9388df19d3 refactor: Replace getXName().c_str(ctx) with ctx->nameOfX 
This makes the ongoing migration to IdStringList easier.

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.
