UriParser:Parse expects that host name doesn't contain special URL symbols -
":", ";", "$",...
However, in case of adb protocol (adb://$device_serial_no:$port) it poses a
problem - device serial number may contain a colon ("192.168.0.1:5555").
In order to handle this situation we can pass URL encoded serial number
(adb://192.168.100.132%3A5555:5432) and decode URL components within
UriParser::Parse.
As an alternative, there is an option to have a adb-specific regexp in
UriParser::Parse but I would like to keep UriParser protocol-independent.
