LZ4 compression support in ZFS.

(Note: sys/conf/files change omitted from this changeset).
MFC 234927:
- Don't log messages saying that accounting is being disabled and enabled
  if the accounting log file is atomically replaced with a new file
  (such as during log rotation).
- Simplify accounting log rotation a bit.  There is no need to re-run
  accton(8) after renaming the new log file to it's real name.

MFC 239356,239564:
Teach dhclient to track changes in link state and to enter the reboot
state when the link on an interface goes up causing dhclient to attempt
to renew its existing lease.

MFC 240467:
Ignore stop and continue signals sent to an exiting process.  Stop signals
set p_xstat to the signal that triggered the stop, but p_xstat is also
used to hold the exit status of an exiting process.  Without this change,
a stop signal that arrived after a process was marked P_WEXIT but before
it was marked a zombie would overwrite the exit status with the stop signal
number.
MFC 240473:
Add some registers defined in PCI 3.0 including new AER bits.
MFC r247034:
  Check if the -sec option is given without an argument.

MFC 240474:
- Denote PCI-e endpoints that support FLR.
- Make parsing of PCI-e extended capabilities assume that future version
  numbers are backwards compatible.
- Add new AER error descriptions.
- Add descriptions for more PCI-e extended capabilities.
MFC 240692,241228:
Adjust the ioctl workaround from r234501:
- Ensure the native ioctl path always allocates a 4kb buffer if a request
  uses a buffer size of 0.
- Rounding all small requests up to 32k swamped the controller causing
  firmware hangs.  Instead, round requests smaller than 64k up to the next
  power of 2 as a general rule.  To handle the one known special case of a
  command that accepts a 12k buffer returning a 24k-ish reply, round
  requests between 8k and 16k up to 32k rather than 16k.  The result is
  that commands less than 8k should now be rounded up to a smaller size
  (either 4k or 8k) rather than 32k.

Upgrade to bzip2 version 1.0.6.
When getting the MIB, remove largest suffix instead of smallest suffix of

Remove DEV_NETMAP from stable/8 options, this was suggested
and approved by the owner, although there is code in some
drivers in support of it, the feature itself is not fully
supported in this release.
