32f2ec86c4 Rework FPGA interchange site router. 
The new site router should be robust to most situations, and isn't
significantly slower with the use of caching.

e7d81913a4 Add "checkPipAvailForNet" to Arch API. 
This is important for distiguishing valid pseudo pips in the FPGA
interchange arch. This also avoids a double or triple lookup of
pip->net map.

fe4608386e Split nextpnr.h to allow for linear inclusion. 
"nextpnr.h" is no longer the god header.  Important improvements:

 - Functions in log.h can be used without including
   BaseCtx/Arch/Context. This means that log_X functions can be called
   without included "nextpnr.h"

 - NPNR_ASSERT can be used without including "nextpnr.h" by including
   "nextpnr_assertions.h".  This allows NPNR_ASSERT to be used safely in
   any header file.

 - Types defined in "archdefs.h" are now available without including
   BaseCtx/Arch/Context.  This means that utility classes that will be
   used inside of BaseCtx/Arch/Context can be defined safely in a
   self-contained header.

a30043c8da Fix assorted bugs in FPGA interchange. 
Fixes:
 - Only use map constant pins during routing, and not during placement.
 - Unmapped cell ports have no BEL pins.
 - Fix SiteRouter congestion not taking into account initial expansion.
 - Fix psuedo-site pip output.

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.
