phases: sparsify phase lists

When the internal and archived phase was added, allphase became a large,
sparsely populated list. This dramatically increased the number of
lookup operations for public relations in `phasecache.phase`. As a first
step, define allphases and related lists explicitly to contain only the
actual phases. Make phasenames a dictionary and create corresponding
dictionaries for mapping phase names back to numbers. Adjust various
list to be sparse as well with the exception of phaseroots and phasesets
members of phasecache. Keep those as a separate step as it involves
changes to the C module.
