a32ad13a86 ecp5: Don't segfault while packing FFs when DI port of TRELLIS_FF unconnected 
Currently a segfault happens when the DI port is not specified. Leaving
it unconnected is probably incorrect, but it shouldn't crash the placer.
Fix by adding a check.

86699b42f6 Switch to potentially-sparse net users array 
This uses a new data structure for net.users that allows gaps, so
removing a port from a net is no longer an O(n) operation on the number
of users the net has.

e6006805ce Make EXTREFB handling more robust 
Avoids a segfault if an EXTREFB does not connect directly to its associated DCUA.
Also adds location constraints specifically for EXTREFB.

Add check_alu to Ecp5Packer 
Checks that every ALU54B is correctly connected to two MULT18X18Ds:

* SIGNEDIA and SIGNEDIB connected to SIGNEDP
* MA and MB connected to P
* A and B connected to {ROA, ROB}

Diamond enforces these requirements; the connections are fixed
in any event so no other connection is possible.

7922b3bfc4 Replace DelayInfo with DelayPair/DelayQuad 
This replaces the arch-specific DelayInfo structure with new DelayPair
(min/max only) and DelayQuad (min/max for both rise and fall) structures
that form part of common code.

This further reduces the amount of arch-specific code; and also provides
useful data structures for timing analysis which will need to delay
with pairs/quads of delays as it is improved.

While there may be a small performance cost to arches that didn't
separate the rise/fall cases (arches that aren't currently separating
the min/max cases just need to be fixed...) in DelayInfo, my expectation
is that inlining will mean this doesn't make much difference.

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.
