* sqlite: use Arc instead of Copy-able StatementHandle
This guarantees that StatementHandle is never used after calling
`sqlite3_finalize`. Now `sqlite3_finalize` is only called when
StatementHandle is dropped.
(cherry picked from commit 5eebc05dc371512bae14cf94498087bdadeddec0)
* sqlite: use Weak poiter to StatementHandle in the worker
Otherwise some tests fail to close connection.
(cherry picked from commit 5461eeeee30772e54e8874f60805b04bdc989278)
* Fix segfault due to race condition in sqlite (#1300)
(cherry picked from commit bb62cf767e3e44896bf4607da8e18237241ed170)
* fix(sqlite): run `sqlite3_reset()` in `StatementWorker`
this avoids possible race conditions without using a mutex
* fix(sqlite): have `StatementWorker` keep a strong ref to `ConnectionHandle`
this should prevent the database handle from being finalized before all statement handles
have been finalized
* fix(sqlite/test): make `concurrent_resets_dont_segfault` runtime-agnostic
