* 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 5eebc05dc3)
* sqlite: use Weak poiter to StatementHandle in the worker
Otherwise some tests fail to close connection.
(cherry picked from commit 5461eeeee3)
* Fix segfault due to race condition in sqlite (#1300)
(cherry picked from commit bb62cf767e)
* 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

* a task that is marked woken but didn't actually wake before being cancelled will instead wake the next task in the queue
* a task that wakes but doesn't get a connection will put itself back in the queue instead of waiting until it times out with no way to be woken
* the idle reaper now won't run if there are tasks waiting for a connection, and also uses
the proper `SharedPool::release()` to return validated connections to the pool so waiting tasks get woken

While running an application a lot of warnings were printed about my
pgpass file, like:
Malformed line in pgpass file
This was due to the fact that my pgpass file contains whitespace and
comments to organize it in a better way.
This commit ensures we will ignore empty lines and lines that (barring
whitespace) start with a comment. This is in line with how PostgreSQL
treats these entries in the pgpass file:
- https://www.postgresql.org/docs/current/libpq-pgpass.html
- function passwordFromFile in src/interfaces/libpq/fe-connect.c
Unlike `Executor.fetch_optional()`, `Executor.fetch_many()` does not
have a single exit. The stream can be dropped at any time. To catch
this event, we create a `StatementResetter` structure inside the stream
loop and reset the statement when it is dropped.
A test case `it_resets_prepared_statement_after_fetch_many` is
similar to `it_resets_prepared_statement_after_fetch_one` which tests
`Executor.fetch_optional()`.
64-bit pointers can't be casted to i32 correctly.
It does not seem to cause problems on amd64 as long as both pointers
reside in the same page, but it's not correct generally.
The provided callback doesn't need to be `'static`. It should be enough that it doesn't borrow anything from the `Connection` itself, even if it does borrow data from elsewhere.
