1d7429f1d7 match: avoid recording full paths 
Use a syntax object to store a source location, letting the
marshal process for syntax objects deal with non-relative
paths.

2743ea06bb avoid paths in case-lambda names

`lambda`.

3d7d906cc1 tweak and clean up the contract combinators api 
- uniformly remove the extra layers of calls to unknown functions for
  chapereone-of?  checks that make sure that chaperone contracts are
  well-behaved (put those checks only in contracts that are created
  outside racket/contract)

- clean up and simplify how missing projection functions are created
  (val-first vs late-neg vs the regular ones)

- add some logging to more accurately tell when late-neg projections
  aren't being used

- port the contract combinator that ->m uses to use late-neg

- port the </c combinator to use late-neg

e44926fcee increemntal GC: compact when a major GC is forced early 
This change further defends against fragmentation when

b5131321d7 force non-inremental GC if excessive fragmentation 
Increemntal GC skips the old-generation compaction phase.
For most applications, that's ok, but it's possible for
fragmentation to get out of hand. Detect that situation
and fall back to non-incremental mode for one major GC.

7e949d5513 GC: skip memory accounting if demand goes away 
Memory accounting is enabled on demand; if demand goes
away --- as approximated by no live custodians having
a limit or previously been queried for memory use ---
then stop accounting until demand resumes.

bef34606cb incremental GC: fix handling of ephemerons 
Fix the case that an old-generation finalizer ends up
on a modified page after all old-generation marking
is complete.

Also, make sure epehemerons are checked after previous
marking that may have left the stack empty.

fa3cabd681 incremental GC: avoid allocating immobile on old-generation page 
The allocation strategy for immobile objects avoids some fragmentation
in non-incremental mode, but it interferes with finishing up an
incremental major collection, so trade some fragmentation for
an earlier finish (which is far more likely to use less memory
instead of more, despite extra fragmentation).

a389678556 improve interaction of incremental mode and finalization 
Really, just improve when majors GCs are forced to trigger
further finalizations. This improvement makes `(collect-garbage)`
followed by `(collect-garbage 'incremental)` move more
reliably into incremental mode.

c3ac1c6bf4 reduce incremental work on (collect-garbage 'minor) 
When `(collect-garbage 'minor)` is combined with incremental
mode, do less incremental work. At the same time, don't
skip an incremental GC just because a major GC is ready.
