Revert "microkernel/mach/gnumach -> microkernel/mach/gnu_mach"

This reverts commit ae9e4e22a7ce8b2b56e98ff1708c2e8d42eefd69.  I've changed my
mind again.  Also resolve conflicts and adapt all new uses of the path.

+# Restructure the tree in a sane way
+
+Merge `linux/src` and `linux/dev`.  But only if using a sane RCS, so leave it
+as-is for now.  Also, a bunch of (header) files from there may probably be
+discarded.
+
+
+# Remove dead files from the GNU Mach source tree
+
+For *exported* files (via `make install`), the plan is to first stick some
+`#error This file is scheduled for removal.  Write to <bug-hurd@gnu.org> if you
+have a reason to have it kept available.` into them, and then actually remove
+them after some months.
+
+For some of the internal header files (containing function prototypes and the
+like), it might actually be useful to use them.  (And then get rid of a bunch
+of `extern ...` statements in other files.)
+
+This following list was assembled by putting such a `#error ...` line into each
+of the `gnumach-1-branch`'s header files (exported and internal; save the
+`linux/` ones (only internal) for simplicity), and then trying to build GNU
+Mach until this would succeed again (by removing offending `#error ...`s), and
+afterwards using the set of exported files for building a cross toolchain
+(again still removing offending `#error ...`s).  A very crude and imprecise
+method.
+
+So, additionally to the list given below, there may actually be a bunch of
+further files (also exported ones) that serve no real value, but are being
+`#include`d through one way or another.
+
+* [[source_gnumach-1-branch ddb/db_expr.h]]
+
+    Currently used, but copyright violation?  Rewrite?
+
+* [[source_gnumach-1-branch ddb/db_print.h]]
+
+    Copyright violation?  Currently unused, but could be used in principle (or
+    be rewritten, to avoid the copyright oddity).
+
+* [[source_gnumach-1-branch ddb/tr.h]]
+
+    Copyright violation.  Unused.  Remove.
+
+* [[source_gnumach-1-branch device/dev_master.h]]
+
+    Might be usable for SMP?  Remove otherwise.
