this makes the distinction between an "access name" and
an "access value" and talks about which is expected for
commands. most are "access name or value".

this changes globalFlags to be a ulext.External
interface value that is passed to each command.
rather than have the ulext.External have a Setup
call in the way that the projectProvider used to
we make all of the state arguments to the functions
and have the commands call setup themselves.
the reason it is in its own package is so that
cmd/uplinkng can import cmd/uplinkng/ultest
but cmd/uplinkng/ultest needs to refer to whatever
the interface type is to call the function that
creates the commands.
there's also quite a bit of shuffling around of
code and names. sorry if that makes it tricky
to review. there should be no logic changes, though.
a side benefit is there's no longer a need to do
a type assertion in ultest to make it set the
fake filesystem to use. that can be passed in
directly now. additionally, this makes the
access commands much easier to test.

this adds a helper method to prompt for a line of
input using the clingy context to the global flag
state that errors if interactive mode is disabled.
