5c0956d7b1 more memory accounting fixes for places 
Fix memory accounting to detect when messages pile up in a
place channel and when shared values (such as the result of
`make-shared-bytes') pile up. Also fix problems where a GC
or free-page purge needs to be triggered.

The implementation causes a minor API change, which is that
a place channel sent multiple times as a message generates
values that are `equal?' but no longer eq?'.

Closes PR 12273

ec380e34ed remove built-in reader and printing support for Honu 
This is a backward-incompatible change, but I think it's
unlikely that any code depends on the removed bindings
or reader syntax.

73071ad186 improve GC logging (3m) 
Show process time of start of GC and otherwise adjust to make
the output more compact, and attach a prefab struct to the
logged message to report all available data in Racket form
(including real start and end times, which are not shown in
the output).

ac8990d519 add date*' and exn:fail:syntax:unbound' 
The `date*' structure type is an extension of `date' with
`nanosecond' and `time-zone-name' fields.

The `seconds->date' function now accepts a real and returns a
`date*'. The fractional part of its argument goes into the
`nanosecond' field.

0197902309 add var-ref->mod-decl-insp' and switch cur-code-insp' uses 
Macros and other tools that need syntax privilege used
`(current-code-inspector)' at the module top-level to try to
capture the right code inspector at load time. It's more
consistent to instead use the enclosing module's declaration-time
inspector, and `var-ref->mod-decl-insp' provides that. The
new function works only on references to anonymous variables,
which limits access to the inspector.

The real function name is longer, of course.

01396784c9 Fix set/c to conform to hash/c-like restrictions. 
Since sets are implemented using the elements as the domain of a hash table,
the following must be true:
 * element contracts for (seteq ...) must be flat
 * element contracts for (seteqv ...) must be flat
 * element contracts for (set ...) must be chaperones, and the resulting
   contract is a chaperone contract

Also, change higher-order set/c contracts to be chaperone contracts
due to the new restrictions.

db7f2b4542 Add a new #:dont-re-require-enter' flag for enter!', to avoid 
requiring itself into the entered namespace.

This makes it useful in some cases where this require leads to a
dependency cycle, eg (enter! racket/list).  It's obviously not useful
for use as-is, since you will not have a bound `enter!' to get out of
the namespace (and possibly no `require' to get it) -- but it is useful
for meta-tools like xrepl.  This is why the flag is verbose.  `xrepl'
now uses this flag.

Also, the check for valid keywords for the form is now done at runtime
rather than in the macro.  This doesn't matter in this case, since the
form is intended for interactive use anyway.

Also, separate the two parts of `enter-load/use-compiled' (it was
defined curried, but didn't use it).
