This attempts to make a search-list pathname fill the host slot of a
pathname with a search-list object instead of the current scheme which
uses a unix host for the host and puts the search-list as the first
part of the directory slot.

 code/pathname.lisp::
  * Make SEARCH-LIST as subtype of HOST, defining appropriate parsers
    and unparsers.
 code/filesys.lisp:
  * Update PARSE-UNIX-NAMESTRING (which also handles search-lists) to
    return the search-list object as the host instead of putting in
    the directory part.

Check that the start and end indices make sense for the given
strings.  This is important before we start bashing random parts of
the string, potentially overwriting other objects.

This fixes the immediate issue, but there are still problems with
very long strings.  The bit-index for such strings won't fit in an
(unsigned-byte 32).

vm-fndb.lisp:
o Correct the defknown to have the correct arg types (vm::offset
  instead of index).

vm-tran.lisp:
o Update deftransform to use vm::offset instead of index.

Config.sparc_common:
o Enable ASSEM_SRC, ARCH_SRC, OS_SRC, OS_LIBS again

Config.sparc_gcc:
o Don't use -traditional-cpp when creating dependencies because that
  causes the old (varargs.h) version of va_start to be used instead of
  the stdard.h version we want.

Config.sparc_sunc:
o Remove ASSEM_SRC, ARCH_SRC, OS_SRC, OS_LINK_FLAGS, and OS_LIBS since
  they're in Config.sparc_common.
