Sandeep Patil	54d8721374	libmeminfo: Add libmeminfo to gather global and per-process memory stats ... The library is expected to be a unified place for all components to read both global and per-process memory accounting form kernel including getting the working set. This change adds the PageInfo, MemInfo and ProcMemInfo classes and verifies the implementation against libpagemap for correctness. Adds a procmem2 tool show the usage. TODO: Plumbing in os_debug, add vmastats, zoneinfo etc parsing.
