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.

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.
