opensolaris code: translate INVARIANTS to DEBUG and ZFS_DEBUG
Do this by forcing inclusion of sys/cddl/compat/opensolaris/sys/debug_compat.h via -include option into all source files from OpenSolaris. Note that this -include option must always be after -include opt_global.h.
Additionally, remove forced definition of DEBUG for some modules and fix their build without DEBUG.
Also, meaning of DEBUG was overloaded to enable WITNESS support for some OpenSolaris (primarily ZFS) locks. Now this overloading is removed and that use of DEBUG is replaced with a new option OPENSOLARIS_WITNESS.

Add FBT for PowerPC DTrace. Also, clean up the DTrace assembly code, much of which is not necessary for PowerPC.
The FBT module can likely be factored into 3 separate files: common, intel, and powerpc, rather than duplicating most of the code between the x86 and PowerPC flavors.
All DTrace modules for PowerPC will be MFC'd together once Fasttrap is completed.

The dtnfsclient module dependency should only be added if the old NFS client support was compiled in.

Initial commit of an I/O provider for DTrace on FreeBSD.
These probes are most useful when looking into the structures they provide, which are listed in io.d. For example:
dtrace -n 'io:genunix::start { printf("%d\n", args[0]->bio_bcount); }'
Note that the I/O systems in FreeBSD and Solaris/Illumos are sufficiently different that there is not a 1:1 mapping from scripts that work with one to the other. MFC after: 1 month

Add DTrace support to the new NFS client. This is essentially cloned from the old NFS client, plus additions for NFSv4. A review of this code is in progress, however it was felt by the reviewer that it could go in now, before code slush. Any changes required by the review can be committed as bug fixes later.

add DTrace systrace support for linux32 and freebsd32 on amd64 syscalls
Add systrace_linux32 and systrace_freebsd32 modules which provide support for tracing compat system calls in addition to native system call tracing provided by systrace module.
Provided that all the systrace modules are loaded now you can select what syscalls to trace in the following manner:
syscall::xxx:yyy - work on all system calls that match the specification syscall:freebsd:xxx:yyy - only native system calls syscall:linux32:xxx:yyy - linux32 compat system calls syscall:freebsd32:xxx:yyy - freebsd32 compat system calls on amd64

Add the OpenSolaris dtrace lockstat provider. The lockstat provider adds probes for mutexes, reader/writer and shared/exclusive locks to gather contention statistics and other locking information for dtrace scripts, the lockstat(1M) command and other potential consumers.

Add dtnfsclient, a first cut at an NFSv2/v3 client reuest DTrace provider. The NFS client exposes 'start' and 'done' probes for NFSv2 and NFSv3 RPCs when using the new RPC implementation, passing in the vnode, mbuf chain, credential, and NFSv2 or NFSv3 procedure number. For 'done' probes, the error number is also available.
Probes are named in the following way:
... nfsclient:nfs2:write:start nfsclient:nfs2:write:done ... nfsclient:nfs3:access:start nfsclient:nfs3:access:done ...
Access to the unmarshalled arguments is not easily available at this point in the stack, but the passed probe arguments are sufficient to to a lot of interesting things in practice. Technically, these probes may cover multiple RPC retransmits, and even transactions if the transaction ID change as a result of authentication failure or a jukebox error from the server, but usefully capture the intent of a single NFS request, such as access, getattr, write, etc.
Typical use might involve profiling RPC latency by system call, number of RPCs, how often a getattr leads to a call to access, when failed access control checks occur, etc. More detailed RPC information might best be provided by adding a krpc provider. It would also be useful to add NFS client probes for events such as the access cache or attribute cache satisfying requests without an RPC.
