This change removes all gendered language that did not refer specifically
to an individual person or pet. The convention taken was to use
variations on "they" when referring to users and/or human beings, while
using "it" when referring to code, functions, and/or libraries.
Additionally, we took the liberty to fix up any whitespace issues that
were found in any files that were already being modified.

Closes#5176
nvlist_pack() and nvlist_unpack are implemented recursively, which can
cause the stack to overflow with a deeply nested nvlist; i.e. an nvlist
which contains an nvlist, which contains an nvlist, which...
Unprivileged users can pass an nvlist to the kernel via certain ioctls
on /dev/zfs, which the kernel will unpack without additional permission
checking or validation. Therefore, an unprivileged user can cause the
kernel's stack to overflow and panic.
Ideally, these functions would be implemented non-recursively. As a
quick fix, this patch limits the depth of the recursion and returns an
error when attempting to pack and unpack a deeply-nested nvlist.

The indefinite article before nvlist should be "an", not "a".
We have 27 "an nvlist" and 7 "a nvlist" in our comment, they should
stay the same as we are such a strict filesystem.

Closes#4941
In the original implementation of the SPL wrappers were provided
for module initialization and cleanup. This was done to abstract
away any compatibility code which might be needed for the SPL.
As it turned out the only significant compatibility issue was that
the default pwd during module load differed under Illumos and Linux.
Since this is such as minor thing and the wrappers complicate the
code they are being retired.

Inclusion of SPL compatibility headers was moved out of the public
header sys/types.h to avoid conflicts with external packages. Include a
few compatiblity headers explicitly to cope with that change. Also,
sort some linux-specific inclusions alphabetically.

The mis-aligned memory accesses in nvpair_native_embedded() and
nvpair_native_embedded_array() will cause a 'Bus Error' for
architectures such as Sparc which not fully byte addressible.
To avoid this issue care is taken to avoid dereferencing the
potentially mis-aligned packed nvlist_t.

This change is related to commit 81eaf15 which ensured the correct
allocation handlers were installed for nvlist_alloc(). The nvlist
functions nvlist_dup(), nvlist_pack(), and nvlist_unpack() suffer
from the same issue and have been updated accordingly.

Issue #1937
The vast majority of these changes are in Linux specific code.
They are the result of not having an automated style checker to
validate the code when it was originally written. Others were
caused when the common code was slightly adjusted for Linux.
This patch contains no functional changes. It only refreshes
the code to conform to style guide.
Everyone submitting patches for inclusion upstream should now
run 'make checkstyle' and resolve any warning prior to opening
a pull request. The automated builders have been updated to
fail a build if when 'make checkstyle' detects an issue.

Use the standard Linux MODULE_VERSION macro to expose the installed
zavl, znvpair, zunicode, zcommon, zfs, and zpios module versions.
This will also automatically add a checksum of the .c files and

Closes#1923
The non-blocking allocation handlers in nvlist_alloc() would be
mistakenly assigned if any flags other than KM_SLEEP were passed.
This meant that nvlists allocated with KM_PUSHPUSH or other KM_*
debug flags were effectively always using atomic allocations.
While these failures were unlikely it could lead to assertions
because KM_PUSHPAGE allocations in particular are guaranteed to
succeed or block. They must never fail.
Since the existing API does not allow us to pass allocation
flags to the private allocators the cleanest thing to do is to
add a KM_PUSHPAGE allocator.
