[trasz] Add kern.racct.enable tunable and RACCT_DISABLED config option.
The point of this is to be able to add RACCT (with RACCT_DISABLED)
to GENERIC, to avoid having to rebuild the kernel to use rctl(8).
[whu] Microsoft vmbus, storage and other related driver enhancements for HyperV.
- Vmbus multi channel support.
- Vector interrupt support.
- Signal optimization.
- Storvsc driver performance improvement.
- Scatter and gather support for storvsc driver.
- Minor bug fix for KVP driver.
Thanks royger, jhb and delphij from FreeBSD community for the reviews
and comments. Also thanks Hovy Xu from NetApp for the contributions to
the storvsc driver.
[ngie] ATF_REQUIRE_KERNEL_MODULE: use atf_skip, not ATF_REQUIRE_MSG so the testcase
no longer bombs out
PLAIN_REQUIRE_KERNEL_MODULE: use printf + _exit, no err so the testcase no
longer bombs out if it prints to stderr
[scottl] Improve support for blacklisting bad memory locations. The user can supply
a text file with a list of physical memory addresses to exclude, and have it
loaded at boot time via the provided example in loader.conf. The tunable
'vm.blacklist' remains, but using an external file means that there's no
practical limit to the size of the list. This change also improves the
scanning algorithm for processing the list, scanning the list only once
instead of scanning it for every page in the system. Both the sysctl and
the file can be unsorted and contain duplicates so long as each entry is
numeric (decimal or hex) and is separated by a space, comma, or newline
character. The sysctl 'vm.page_blacklist' is now provided to report what
memory locations were successfully excluded.

[royger] vt_vga: add a timeout while waiting for vertical retrace
On one of my systems FreeBSD will fail to boot because vt_vga gets stuck
waiting for the vertical retrace if there's no monitor attached. Fix this by
adding a timeout and exiting if the vertical retrace times out.
