libalpm: introduce a usage level for repos

This defines a level of interest a user has in a repository. These are
described by the bitmask flags in the alpm_db_usage_t enum:

  ALPM_DB_USAGE_SEARCH: repo is valid for searching
  ALPM_DB_USAGE_INSTALL: repo is valid for installs (e.g. -S pkg)
  ALPM_DB_USAGE_UPGRADE: repo is valid for sysupgrades
  ALPM_DB_USAGE_ALL: all of the above are valid

Explicitly listing the contents of a repo will always be valid, and the
repo will always be refreshed appropriately on sync operations.
