More friendly (permissive) TRAMP path constructions for us humans.

Provides function `friendly-tramp-path-disect` that is a drop-in replacement
for `tramp-dissect-file-name`. It behaves the same but allows the following
formats:

 - `/<method>:[<user>[%<domain>]@]<host>[%<port>][:<localname>]` (regular TRAMP format)
 - `[<user>[%<domain>]@]<host>[%<port>][:<localname>]` (permissive format)
