- build the sub projections only once and build them before getting
the blame objects (instead of after getting the actual values)
- added context information to the blame objects
- added an optional #:min-count argument to insist on a minimum length
for the stream

Also, remove executables (in full setup or "tidy" mode) when the
corresponding collections are removed.
As a result of these changes, `raco pkg' puts launchers from user-scoped
packages in user space and cleans up launchers from removed packages.
There's no attempt to include "launchers.rktd" in a distribution.
That should be ok: having an entry in "launchers.rktd" just
makes a launcher a candidate for removal. Including "launchers.rktd"
would be a hassle for many reasons, including that the initial set
of launchers is platform-specific.
Another run at the problem 57516164de was meant to solve. The
new solution just gives up when a `drawRect:' method is called
in the wrong thread, which might create refresh glitches but
avoids a deadlock in the case that the Racket thread is blocked
on the update happening in the foreign thread.
A constant result for foreign-thread use of a callback allows a
callback to return without synchronizing with the Racket thread.
A constant result is thus useful when a callback's work can simply
be skipped if the callback is applied in the "wrong" OS thread.
Also:
* add a backtracking limit
* check for ground terms in both term and pat environments
when filling in generated patterns
* update tests to be consistent with the above
This termonology change affects lots of function names from `pkg/lib'
and `pkg/db' (former `pkg/pnr-db'), and it also affects some `raco
pkg' commands.
Existing package installations that are marked as 'pnr in a
local configuration are converted automatically to 'catalog, but any
existing "indexes" configuration must be changed to "catalogs".
