Revert "db: use channel instead of semaphore + result variable"
...
Using a sync. channel breaks kill-safety.

fix `ffi/unsafe/nsalloc'
...
Using `call-as-atomic' isn't right, because that allows an escape
via `call-as-nonatomic'. Assuming that `call-as-nonatomic' isn't
used, it seems like `call-as-atomic' should be ok, anyway, but
somehow its leads to unbalanced `end-atomic' calls.

fix editor-canvas%' internal on-size' handling
...
The `on-size' method is called in atomic mode,
and we can't call into the editor's sizing functions
in atomic mode.
Watch out for refresh and/or window-sizing problems.

port position-tracking clean-ups
...
Add `file-position*', which can return #f instead of raising
an exception when a port's position is unknown. Change
`make-input-port' and `make-output-port' to accept more
kinds of values as the initial position.
These changes make it possible to synchronize a port's
position with a `port-commit-peeked' action. It's ugly,
which I think reflect something broken about position
tracking in the port protocol (which seems difficult to fix
without breaking compaibility).

add port shortcut for `make-{input,output}-port'
...
Providing a port instead of a reading or writing procedure
redirects the read/write to the specified port. This shortcut
is kind of a hack, but the run-time system can easily streamline
the redirection when it's exposed this way.
Using the new redirection feature reduces overhead in
`with-output-to-bytes' and `pretty-print'.

change -e to flush aftering printing a result
...
Previously, the use of `pretty-print' for `print' by `racket/main'
and the use of `transplant-output-port' by `pretty-print' caused
a flush to happen.
This problem highlights a potential general issue, which is that
`pretty-print' happened to always flush its output before, and
some programs may accidentally depend on that behavior.
