Stephan Bergmann bd6fb0cd3e Extended loplugin:ostr: Rewrite some O[U]StringLiteral -> O[U]String
...in include files.  This is a mix of automatic rewriting in include files and
manual fixups (mostly addressing loplugin:redundantfcast) in source files that
include those.

existing, the password is checked using the passed password
verifier.

media descriptor is used to request a password from the user. This
will be repeated until the passed password verifier validates the
entered password, or if the user chooses to cancel password input.

default passwords) was found, it will be inserted into the
"Password" property of this descriptor.
