53d6a79d5b unlinkat(2): unlinkat(AT_REMOVEDIR) fails with ENOTEMPTY like rmdir()
for non-empty directories.

POSIX permits both ENOTEMPTY and EEXIST, but we use the clearer ENOTEMPTY,
following BSD tradition.

258458fc8f kvm(3): Mention that some of the functions use sysctl(3) instead of kmem.
Additionally, because of sysctl(3) use (which is generally good), behaviour
for crash dumps differs slightly from behaviour for live kernels and this
will probably never be fixed entirely, so weaken that claim.

Also add xrefs for confstr(3) (as sysconf(3) but for strings) and kvm(3)

e9cfab3d98 - Take libinstall.a out of pkg_install and make it a proper shared library.
- Rework the wrapper support to check libpkg version as well as pkg_install
version.
- Add libfetch to _prebuild_libs.
- There are no new features introduced.

Notes: the API is not stable, so basically, do not use libpkg in your
projects for now. Also there's no manpage for libpkg yet, because the API
will change drastically. I repeat, do not use libpkg for now.

e3a8d034ba getcwd(3): Clarify that EACCES may or may not be checked.
POSIX permits but does not require checking access on the current and parent
directories.

Because various programs do not like it if getcwd(3) fails, it seems best
to avoid checking access as much as possible. There are various reports in
GNATS about this (search for getcwd).

Our getcwd(3) implementation first queries the kernel for the pathname
directly, which does not check any permissions but sometimes fails, and then
falls back to reading all parent directories for the names.

c8c2ee5413 While SPARC V9 allows tininess to be detected either before or after
rounding (impl. dep. #55), the SPARC JPS1 responsible for SPARC64 and
UltraSPARC processors defines that in all cases  tininess is detected
before rounding therefore rounding up to the smallest normalized number
should set the underflow flag. This change is needed for using SoftFloat
on sparc64 for reference purposes.

f7959704e8 libc/db/hash: cap auto-tuned block size with a value that actually works
This fix mostly matters after r206129 that made it possible for
st_blksize to be greater than 4K.  For this reason, this change should
be MFC-ed before r206129.
Also, it seems that all FreeBSD uitlities that use db(3) hash databases
and create new databases in files, specify their own block size value
and thus do not depend on block size autotuning.

4f08ecd7ed Rename st_*timespec fields to st_*tim for POSIX 2008 compliance.
A nice thing about POSIX 2008 is that it finally standardizes a way to
obtain file access/modification/change times in sub-second precision,
namely using struct timespec, which we already have for a very long
time. Unfortunately POSIX uses different names.

This commit adds compatibility macros, so existing code should still
build properly. Also change all source code in the kernel to work
without any of the compatibility macros. This makes it all a less
ambiguous.

I am also renaming st_birthtime to st_birthtim, even though it was a
local extension anyway. It seems Cygwin also has a st_birthtim.

28e4fb3b8e Merge improvements from kernel HID parser to the userland usbhid(3)
parser.  This merge does not change any API and should not break any
native or thirdparty applications.

Changes include:

* Merge multiple report ID support and other improvements from kernel
  HID parser.
* Ignore rid argument in hid_start_parser, parse all the report items since
  we now support multiple report ID.
* Skip report ID byte in hid_get_data() and set report ID byte in
  hid_set_data(), if report ID is non-zero.
* Reimplement hid_get_report_id: instead get report id from uhid device
  (which is always 0), try parsing the report descriptor and return the
  first report ID encountered.
