- match package version numbers with relational operators

Browse source 
- use glob patterns when matching packages by origin

- csh-style {...} choices in glob matching

- pkg_info: new flag -E (list matching package names only)

- pkg_version: new flag -T (test if a given name matches a pattern)

- new flag -X (interpret pattern as an extended regular expression)
