D. Shah 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.

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

D. Shah 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.

Alter MULT18X18D timing db based on register config 
If the REG_INPUTA_CLK and REG_INPUTB_CLK values are set, then we should
use the faster setup/hold timings for the 18x8 multiplier.
Similarly, check the value of REG_OUTPUT_CLK for whether or not to use
faster timings for the output.

This is based on how I currently understand the registers to work - if
anyone knows the actual rules for when each timing applies please do
chime in to correct this implementation if necessary.

Along the same lines, this PR does not address the case when the
pipeline registers are enabled, since it is not clear to me how exactly
that affects the timing.
