fe1ef27d4a META MODE: Update dependencies with 'the-lot' and add missing directories. 
This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so.  A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR.  These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package.  The current implementation of targets/ is
very unmaintainable.

Currently rescue/rescue and sys/modules are still not connected.

74bf082d07 Add a little, but very useful script for use with programs that work using an 
event loop and should sleep only when waiting for events (eg. via kevent(2)).
When a program is going to sleep in the kernel, the script will show its name,
PID, kernel stack trace and userland stack trace. Sleeping in kevent(2) is
ignored as it is expected to be valid.

Sample output:

WITH_META_MODE we get auto objdir creation, the ability to
