Add and document support for using new archive state mode flags. Now

Browse Source 
archived files will show up as either "a" (S_ARCH1) or "A" (S_ARCH2)
in ls -l. As noted, archive state is fs-dependent, and not maintained
by most fs's.

Archive state 1 and archive state 2 represent file system dependent
archive state for a file. Most file systems do not retain file archive
state, and so will not report files in either archive state.
msdosfs will report a file in archive state 1 if it has been
archived more recently than modified. Hierarchical storage systems
may have multiple archive states for a file and may define archive
states 1 and 2 as appropriate.
