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.

It's not clear that any limit is still needed, and probably

integers (but I don't want to spend that kind of time
right now).

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).
