* 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.

Previously MX records were queried only for OAuth 2 configuration and
did not affect the list of servers tried. User was required to manually
configure the servers for Google Workspace (former GSuite) domains.
Now MX records are queried during configuration. If provider is found in
offline database, its ID, corresponding to the filename, is saved as
`configured_provider`.
`configured_provider` is also set during database migration if email
address uses the domain from the provider database, but no MX querying
is done.
LoginParamNew structure, which contained possible IMAP and SMTP
configurations to try is replaced with uniform vectors of ServerParams
structures. These vectors are initialized from provider database, online
Mozilla or Outlook XML configuration or user entered parameters.
During configuration, vectors of ServerParams are expanded to replace
unknown values with all possible variants, which are tried one by one
until configuration succeeds or all variants for a particular protocol
(IMAP or SMTP) are exhausted.
ServerParams structure is moved into configure submodule, and all
dependencies on it outside of this submodule are removed.
Rustls does not offer a documented way to accept valid certificates with
invalid hostnames. Implementation of certificate verification in Rustls
does not have a public API and reimplementing it is error-prone.
if the past we had lots of crashes because of unexpected unwrap failures,
mostly related to string.
this commit avoids them eg. for string-conversions that may panic
eg. when encountering a null-byte or by logical programming errors
where an object is assumed to be set but is not under unexpected circumstances.
