qt: Add support for flags in LDAP server options

Browse Source 
* lang/qt/src/qgpgmenewcryptoconfig.cpp (parseURL): Handle extended
LDAP server option syntax.
(portToString): New.
(splitURL): Append flags to LDAP server option.
--

This adds support for the extended syntax of LDAP server options
introduced in gpg 2.2.18/2.3. The flags are stored as fragment of a
QUrl.
