Loading `db/sqlite3' no longer raises an exception if
the SQLite library isn't found. Instead, `sqlite3-connect'
raises an exception, while `sqlite3-available?' reports
whether it will work.
The dynamic test allows the documentation-help system
to continue to work if SQLite3 is not available. Currently,
though, `raco setup' still insists on using SQLite3 to
build the database of documented tags.
The `xref' produced by `setup/xref' uses the database to delay
loading "out.sxref"s, which cuts 64-bit DrRacket's initial
footprint by around 50MB (i.e., about 20%).

Extends append-editor-operation-menu-items so that when you
pass an editor and a position, it checks to see if that spot
has a non-string% snip and, if so, copies that one position
(or cuts it, depending).
Then, use that extension in DrRacket

when the blue box doesn't fit in the visible region
in one direction (either x or y) but does fit
in the other region, then it was being drawn in
the wrong place
This code is still sub-optimal, since it isn't leaving
space for the words underneath the lock in the case
the lock is near the bottom of the visible region, but
it seems better to just let that be invisible rather
than make the lock float a bit in that case.

Fixes a memory leak in SSL_get_peer_certificate.
Fixes a memory leak (finalizer closure refers to obj) in create-ssl
for _SSL* obj. Correcting the finalizer to run caused mem corruption
(possibly due to double-freeing in mzssl-release, despite cancel box)
but changing to allocator/deallocator seems to avoid the problem.
- add enqueue-front!
- add queue-filter!
- use the predicates instead of the /c contracts
- make queue-length take constant time
- add some random tests
- note the running times of all of the operations in the docs
- make queues be sequences directly (and use make-do-sequence
to implement in-queue instead of building a list)
- added non-empty-queue? (note extra hypen as compared
to the past; this seems better since the function
wasn't exported before and we already have other
functions named "non-empty-<something>" but not
others namedn "nonempty-<something>")
