Moved custom ToSql trait including Send + Sync from lib.rs to sql.rs.
Replaced most params! and paramsv! macro usage with tuples.
Replaced paramsv! and params_iterv! with params_slice!,
because there is no need to construct a vector.
as by reviving qr codes,
there may be more than one token for a chat,
ensure, the most recent token and only one token is returned
by the sql-command for looking up tokens
(used for generating new codes)
* Remove sql::error submodule
Use anyhow errors instead.
* Remove explicit checks for open SQL connection
An error will be thrown anyway during attempt to execute query.
* Don't use `with_conn()` and remove it
* Remove unused `with_conn_async`
* Resultify markseen_msgs
Switches from rusqlite to sqlx to have a fully async based interface
to sqlite.

Function `query_row` executes query and calls callback function to process
row returned. Function query_row_col() is special case, that provides
callback function, which returns value of one particular column of row,
ignoring others.
In all cases, that particular column was 0 (first and only column of
query result), since there is no point to select more than one column
with this function -- they are discarded anyway.
This commit removes that redundancy, removing column number argument of
query_row_col() function and adjusting call sites accordingly.
