The Vma and ProcMemInfo objects do not need separate stats
objects for storing working set. The Vma either has working set
or memory usage information and never both.

Implement procrank using new libmeminfo APIs. procrank2 is functionally
equivalent to procrank except for the part where the old procrank would
print processes under each oomadj level if called with 'procrank -c -o'.
The output format of 'procrank2' is identical to that of 'procrank'.
'procrank2' also gives significant performance boost over 'procrank' but
does cost a more memory as the library is written to 99% use case where
callers almost always want to read the memory usage of hte process.
