reimplemented 'wscons' interfaces.
mostly sync with changes on the trunk
sync with changes in trunk.
sync __BROKEN_INDIRECT_CONFIG removal with trunk.
move wscons file specs into their own file, since eventually I hope this to

localized.  8-)
add support for reading gzipped kernels.
reorganize Alpha boot block sources: put common sources in a 'common'
directory (so they don't clutter up the arch/alpha/stand), and put
not-common sources in programs' directories.
