5ec5669275 There is a lot of commented out code here which applies to future work
for userland tracing.

For now we need the basic functions to be in place so that DTrace can
be used for kernel tracing.

cccc7d47c0 Merge FreeBSD include file changes with some code that should have come
in on the vendor branch.

bbda5851ce * Use FreeBSD's process library instead of the Solaris one.
* There are a few placeholders in here for which there isn't libproc
  support code yet. This is relevent to userland tracing. This set of
  commits is designed to get kernel tracing up and running, with the
  userland stuff to follow later.

768c574fc0 There are many places in libdtrace where errno can be set. When an
error is returned all the way back to the dtrace app, it's hard to
figure out where that error came from.

Add a couple of functions to get and set the error location which can
be optionally compiled into the library.

b29602e4d8 * Get the maximum number of CPUs via a sysctl.
* Handle the different ioctl design.
* Support the freopen() changes.
* Use functions in FreeBSD's process library rather than the CDDL
  library that Solaris has which sits on top of their process file
  system and is therefore unsuitable for use on FreeBSD. The libproc
  API for FreeBSD is deliberately different to that on Solaris because
  Sun wouldn't release the libproc.h header under a BSD license.

51e031e870 * Define YY_INPUT for flex since input() can't be re-defined.
* On FreeBSD define both LITTLE_ENDIAN and BIG_ENDIAN and then set the
  BYTE_ORDER to the one we are using. On Solaris they define one or
  the other but not both. For us to keep using FreeBSD header files,
  we need to use endian definitions the same way we do in pure BSD
  code.

18db5bcf28 Simplify for FreeBSD for now, bypassing the multibyte char variables
that Solaris has. We may need to revisit this issue later.

76429c36b0 Solaris has code which makes zlib optional, so they have to jump through
some hoops to get the compression functions. On FreeBSD have libz and
can just link against it.

9de81c7273 MFp4:
@118370	Correct typo.

@118371	Integrate changes from vendor.

@118491	Show backtrace on unexpected code paths.

@118494	Integrate changes from vendor.

@118504	Fix sendfile(2). I had two ways of fixing it:
	1. Fixing sendfile(2) itself to use VOP_GETPAGES() instead of
	   hacking around with vn_rdwr(UIO_NOCOPY), which was suggested
	   by ups.
	2. Modify ZFS behaviour to handle this special case.

	Although 1 is more correct, I've choosen 2, because hack from 1
	have a side-effect of beeing faster - it reads ahead MAXBSIZE
	bytes instead of reading page by page. This is not easy to implement
	with VOP_GETPAGES(), at least not for me in this very moment.

	Reported by:	Andrey V. Elsukov <bu7cher@yandex.ru>

@118525	Reorganize the code to reduce diff.

@118526	This code path is expected. It is simply when file is opened with
	O_FSYNC flag.

3d357b8835 Fix build breakage. Most of ZFS code is also compiled in userland and I
should really stop forgetting about that.

01498c0b83 In FreeBSD,
- cv_timedwait() takes delta instead of absolute time,
- we need ioctl() for mediasize.

f0a75d274a Please welcome ZFS - The last word in file systems.
ZFS file system was ported from OpenSolaris operating system. The code in under
CDDL license.

I'd like to thank all SUN developers that created this great piece of software.
