gatecat 3b45174375 pyconsole: Avoid lockup when reading from stdin 
Create an empty temporary file for stdin; so reads fail rather than
locking up (otherwise doing help() would be enough to completely lock up
the GUI).

gatecat 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.
