Valid package names
An internal package index accepts uploads only under valid names, stored in their normalised form so that Market_Reports and market-reports can't be two different packages. Write normalize_name(name). A valid name is letters, digits, ., _ and -, and it starts and ends with a letter or digit. Normalising lower-cases the name and turns every run of ., _ and - into a single -.
