41e9e3e5ff db: add `sqlite3-available?'
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.

8db023c624 add string typeid for mysql char(N) fields
closes PR 13255

Need to add tests, but "select cast(? as char(5))" results in var-string,
not string. Only get string typeid when reading from table.

672910f27b Lots of bad TAB eliminations.
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.

If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces.  For example, to see
per-line authors, use "git blame -w <file>".  Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".

ecb88ffd45 Revert "db: use channel instead of semaphore + result variable"
Using a sync. channel breaks kill-safety.

This reverts commit 8363db9258.

   (not a leak, just gc'd very slowly)

This "fixes" the segfault in the test program, but it seems
like there must be another underlying problem.

418985d4c4 db: fixed issues with statement finalization (don't use weak hash)
In some cases, statements were disappearing from statement-table
without being finalized; this makes disconnect fail.
(I was only able to produce the problem when the db lib was
instantiated in a sub custodian that is later shutdown....
like the way the rackunit gui runs the test suite.)
