Add pm_process_usage flags to get memory usage by a process, only
counting pages with specified flags set.

Add pm_map_usage_flags, which is the same as pm_map_usage but only
counts pages with the specified flags set. This can be used to
only count "swapbacked" pages, which are pages that cannot be
flushed back to disk without using swap.

pm_map_usage was not incrementing vss for pages that were in the
process's map but not occupying a physical page. Move the
vss increment above the check for present mappings.

Mappings that are not from a file do not have a name. The sscanf
will read all of the fields up to the name, and then leave name
untouched. This causes the previous name to be reused. Reset
name to an empty string before each call to sscanf.

Fixed these problems:
1. Page swapped bit was not extracted correctly.
2. Pages were ignored when page present bit is not set.
3. Bit operations were not correct.
4. There was a compiler warning about unsigned/signed comparision.
5. Line limit was too short for the map file. This was causing procrank
to generate a warning and remove the related process from results.

Instead of handling maps with the name "[vectors]" specially,
silently ignore EOF when reading from /proc/<pid>/pagemap, which
occurs any time a a mapping is outside of the userspace range.

In kernel 2.6.37, the vector page was added to /proc/<pid>/maps,
but because it is located above TASK_SIZE (usually 0xbf000000),
it is considered to be in the kernel's address space, not the
process', so it doesn't show up in /proc/<pid>/pagemap.
When the vector page is detected, using the name "[vectors]",
remove it from the map.
