Fix the covered step tests.
...
However, there is still a problem with moves where the box is always cut
by the plane: both sides need to be tested (done), but when the first side
checked allows longer motion than the second, but still collides, only the
first side is checked. The shorter motion is required.

Move the start point to the near side of the crossed plane.
...
I'm not sure the end point needs to be moved at all, but I'll leave it
alone for now. I have a couple of failing test cases that seem to be caused
by not handling moves where the box is always cut by the plane.

Correct the sign for the shift in frac.
...
However, this is not entirely correct as the new start point when testing
the other side of the plane also needs to be calculated.

Fix some missing usages of offset.
...
This fixes my one failing box clip test. Now I need to find more broken
cases. At least now, they should be real tests.

Assume the trace will be allsolid.
...
Rather than setting allsolid when the trace fails to leave solid space,
clear it when the trace enters non-solid space. This is necessary because
the trace might visit only one node and thus the failure to leave solid
space will not be detected. This fixes the problem with hipnotic's bobbing
water.

Rename the empty and solid flags, and use them correctly.
...
seen_empty and seen_solid much better reflect their meanings, and also use
them correctly (eg, visiting an empty node does not clear seen_solid).
Hipnotic's bobbing water is still broken, though.

Make MOD_TraceLine behave "correctly".
...
MOD_TraceLine now behaves the same as id's SV_RecursiveHullCheck (from
WinQuake). This means that even if the trace would escape from solid space
into non-solid space, the trace is treated as allsolid if it crosses from
one solid space to another before hitting the empty space.
trace-id.c is used only for establishing the behaviour of id's code.

Clean out the last traces of my boxclip code.
...
I've been experiencing funny trace issues while playing Soul of Evil. While
I think the boxclip dregs shouldn't be causing problems, it's probably best
to clean them out properly before trying to fix anything.

Create and use mclipnode_t.

I didn't realize this was a critical part of fitzquake's large map
support. This should fix the non-solid brush entities in Conflagrant
Rodent.

well, it finally seems to work, but q1 maps (especially start's ramp to e3) are not such that they're particulary playable due to being designed for point clipping. so still disabled until something can be sorted out.

don't stop a trace on transition from solid to non-solid. this fixes the grapple problem in prozaccoop, but really the bug is in the progs but this is a faster fix for now until I decide whether I want to stop a trace on transition or not, or whether to make it optional.

the big dso visibility patch :). Sure, we have to have unique names for static builds, but with controlled visibitly we should get faster program loads (although this isn't C++, so it's not as bad) and complex plugins are cleaner.
