u2c: misc windows fixes

* support globbing/wildcards on windows

* add `osc 9;4` to show upload progress in the taskbar
   (currently windows-only; linux is picking it up)

* workaround msys2-terminal not normalizing
   absolute paths which contain whitespace

* show a helpful "now hashing..." while the
   first file is being hashed, since it kinda
   looks like a deadlock on windows otherwise
