d96700a6da Remove redefinitions of some kernel types from mbuf.d. 
These override the kernel's definitions and do not match in some cases,
which can break scripts that use these types. With r305055, dtrace is able
to trace fields of struct mbuf's anonymous structs and unions, so there is
no need to redefine types already defined in CTF.

18849b5da0 Remove the old version of the DTraceToolkit from the source tree. 
The DTraceToolkit is part of the Open DTrace effort and is supported
on FreeBSD as a port (sysutils/DTraceToolkit) which has been updated
to properly track toolkit development upstream.

480f4e946d Add an mbuf provider to DTrace. 
The mbuf provider is made up of a set of Statically Defined Tracepoints
which help us look into mbufs as they are allocated and freed.  This can be
used to inspect the buffers or for a simplified mbuf leak detector.

New tracepoints are:

mbuf:::m-init
mbuf:::m-gethdr
mbuf:::m-get
mbuf:::m-getcl
mbuf:::m-clget
mbuf:::m-cljget
mbuf:::m-cljset
mbuf:::m-free
mbuf:::m-freem

There is also a translator for mbufs which gives some visibility into the structure,
see mbuf.d for more details.

b1f92fa229 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.

af71f40a98 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:
