None of the new features are implemented yet. This commit just adds the new
protocol definitions and adds backwards-compatibility code for pre 7.23
servers.

Jumping from protocol 7.15 to 7.21 adds several new features. While they're
all potentially useful, they're also all optional, and I'm not implementing
any right now because my highest priority lies in a later version.

fuse_kernel.h is based on Linux's fuse.h. In r349250 I modified
fuse_kernel.h by generating a diff of two versions of Linux's fuse.h and
applying it to our tree. patch succeeded, but it put one chunk in the wrong
location. This commit fixes that. No functional changes.

This protocol level adds two new features: the ability for the server to
store or retrieve data into/from the client's cache. But the messages
aren't defined soundly since they identify the file only by its inode,
without the generation number. So it's possible for them to modify the
wrong file's cache. Also, I don't know of any file systems in ports that
use these messages. So I'm not implementing them. I did add a (disabled)
test for the store message, however.

This protocol version adds one new feature: the ability for the server to
set the maximum number of background requests and a "congestion threshold"
with ill-defined properties. I don't know of any fuse file systems in ports
that use this feature, so I'm not implementing it.

This commit raises the protocol level and adds backwards-compatibility code
to handle structure size changes. It doesn't implement any new features.
The new features added in protocol 7.12 are:
* server-side umask processing (which FreeBSD won't do)
* asynchronous inode and directory entry invalidation (which I'll do next)

This commit adds the definitions for protocol 7.11 but doesn't yet implement
the new features. The new features are optional, so they can come later.

Protocol version 7.10 has only one new feature, and I'm choosing not to
implement it, so this commit is basically a noop. The sole new feature is
the FOPEN_NONSEEKABLE flag, which a fuse file system can return to indicate
that a certain file handle cannot be seeked. However, I'm unaware of any
file system in ports that uses this flag.

This commit upgrades the FUSE API to protocol 7.9 and adds unit tests for
backwards compatibility with servers built for version 7.8. It doesn't
implement any of 7.9's new features yet.

fuse_kernel.h defines the structures used by the FUSE protocol. Originally
it came from libfuse, but the current source of truth is the Linux kernel.
This commit minimizes the diffs between our version and the Linux version as
of 21f3da95d (protocol version 7.8).
The flags field of struct fuse_listxattr_out and fuse_listxattr_in was an
error in our header. Those fields don't exist in Linux or libfuse, and
they've never been used in FreeBSD. In fact, those structs don't even exist
in Linux and libfuse; those projects confusingly overload the identical
fuse_getexattr_in and fuse_getxattr_out structs.

The requested size was returned incorrectly in case uio == NULL from listextattr because the
nameprefix/name conversion was not applied.
Also, make a_size/uio returning logic more unified with other filesystems.

Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
The creation time support breaks the data structures used in linux
fuse. libfuse carries it's own header.
Revert the changes for now. We will try to get an agreement with the
fuse upstream maintainers to avoid having to patch the library
headers all the time.
Recalculate FUSE_COMPAT_ENTRY_OUT_SIZE and COMPAT_ATTR_OUT_SIZE.
These were wrong in the previous commit. They are actually unused
in FreeBSD though.

When birthtime was added (r253331) we missed adding the weight
of the new fields in FUSE_COMPAT_ENTRY_OUT_SIZE and
COMPAT_ATTR_OUT_SIZE. Adjust them accordingly.

Bring in the changes from the FUSE kernel interface 7.10
(available under a BSD license).
After 7.10 the linux FUSE developers added support for a
controversial CUSE driver and some linux especific
features that are unlikely to find its way into FreeBSD.
We currently don't implement any of the new features so we
are *not* bumping the FUSE_KERNEL_MINOR_VERSION. The header
should, nevertheless, serve as a template to add the new
features in a compatible manner.
While here adopt some minor cleanups from the upstream version
like removing FUSE_MAJOR and FUSE_MINOR which were never
used. Also add multiple inclusion header guards,
I was keeping this #ifdef'd for reference with the MacFUSE change[1]
but on second thought, this is a FreeBSD-only header so the SVN
history should be enough.
Add missing padding while here.

This has been developed during 2 summer of code mandates and being revived
by gnn recently.
The functionality in this commit mirrors entirely content of fusefs-kmod
port, which doesn't need to be installed anymore for -CURRENT setups.
In order to get some sparse technical notes, please refer to:
http://lists.freebsd.org/pipermail/freebsd-fs/2012-March/013876.html
or to the project branch:
svn://svn.freebsd.org/base/projects/fuse/
which also contains granular history of changes happened during port
refinements. This commit does not came from the branch reintegration
itself because it seems svn is not behaving properly for this functionaly
at the moment.
