- It is possible to call open() on a directory, but FUSE lowlevel
filesystems don't implement that and expect it to be re-routed to the
opendir call. BRoster uses this to read the dir/file attributes to
identify it, so it could not identify directories properly.
- In ReadDir, make sure to not return more entries than asked, as this
confuses the userlandfs protocol communication (the kernel does not
acknowledge the readdir reply, and then the server hits an assert when
receiving the next request instead of the ack).

- Import latest version of files from FUSE 2.9.9 (our last
synchronization was with 2.7.4)
- Adjust fuse pkgconfig file to use the POSIX error mapper
automatically, since that's required for all FUSE software
- Implement the lowlevel API in addition to the highlevel one. The
lowlevel API uses inode numbers to identify files, rather than paths,
making it a better fit to the userlandfs architecture.
The FUSE 2.x branch is not maintained anymore by FUSE developers,
however, pretty much no one migrated to FUSE 3.x. So it is more
interesting to implement, rather than 3.x.
Confirmed still working with sshfs and curlftpfs.
Example use:
I tested this with github.com/whoozle/android-file-transfer-linux
- Build the fuse library and copy it to ~/config/non-packaged/add-ons/userlandfs/
- Start the server: /system/servers/userlandfs_server aft-mtp-mount
- Connect your Android phone and put it in USB file transfer mode
- Mount the device: mount -t userlandfs -p 'aft-mtp-mount /boot/home/MyPhone -d -o use_ino' ~/MyPhone
- You can now access your phone data

The HashMap and HashSet classes are copied from userlandfs. The
HashMap one works as-is as it's already used in userlandfs; the
HashSet does not even compile yet.

* Add a way for a FUSE module to supply Haiku-specific extensions.
This allows it to integrate better with Haiku while only requiring
minimal changes on the FUSE module itself.
* For now, there is only one extension: another function pointer for
"get_fs_info", which lets the FUSE module fill in an fs_info struct.
FUSE provides no good way to otherwise communicate extra information,
such as the volume flags (e.g. B_FS_IS_SHARED).
* A FUSE module can signal that it supports the Haiku extensions by
a) defining HAS_HAIKU_FUSE_EXTENSIONS before including the fuse
headers
b) setting the global variable gHasHaikuFuseExtensions to 1 in
its initialization
Otherwise, the Haiku extensions are completely invisible to the
FUSE module.
Tracker's OpenHashTable.h which it should eventually replace. We've renamed the
class to BOpenHashTable and changed the interface slightly so that HashTableLink
became superfluous.
Adapted all the code that used it. Since the OpenHashTables no longer clash,
this should fix the GCC4 build.

the current thread, now. Implemented by introducing a new base class
KernelRequest which has respective attributes.
* Server: RequestThreadContext does now also save the request that is being
processed. Furthermore some space has been reserved for file system specific
data, which can be initialized by the new
FileSystem::InitRequestThreadContext().
* FUSE library: Implemented fuse_get_context() using the new
RequestThreadContext feature.

newly created dir. The VFS really doesn't need it and for some file systems
it might not be easy to get by. Several file systems (e.g. rootfs and fat)
were ignoring the parameter anyway.

We do some caching using a hash table indexed by the operations vector.
* Pass the vnode capabilities to the kernel module.
* In the kernel tailor the operation vectors for volumes and vnodes passed to
the VFS according to the respective capabilities. This way those vectors look
pretty much like those from the client FS. This saves unnecessary calls when
hooks are not implemented and should also fix compatibility problems in cases
where not implementing a hook and returning an error don't mean the same to
the VFS.
* Inlined some of the kernel module Volume class getters.

- Send() now also gets the message to send as parameter.
- Added methods to reserve and unreserve space in the buffer.
* RequestAllocator: Uses the port buffer reservation methods now. This allows
to let more than one RequestAllocator use a Port in a stack-like manner.

* Change Port::Receive() semantics. It does no longer use the buffer associated
with the object. Instead it allocates heap memory for the caller. Since
there's only one caller who clones the message anyway, we save one copy this
way (though we have an additional syscall in userland) and don't overwrite
a request being prepared for sending.
* Changed RequestAllocator::ReadRequest() to also read the request from the
port.

already get the first vecs for do_iterative_fd_io() in userland, saving a
trip back and forth.

io() hook. Create a new object (HaikuKernelIORequest) instead and store it

* Added some missing requests in UserlandFSUtil::is_{kernel,userland}_request().

/system/servers, now.
* Got rid of the dispatcher application. It was the entity the kernel module
talked to when mounting a yet unknown FS. It started the client FS server
applications. Now the kernel module starts them directly. They use
respectively named ports, so the kernel module can find them when already
running.

* Split the FSCapabilities bit mask into three bit masks for the FS, the
volume, and the vnodes, since we have three independent FS interface
structures, now. The latter is not supported in the kernel add-on, yet.
* Server:
- Temporarily removed some things from the build (the BeOS interface
and the cache implementations).
- Some WIP in HaikuKernelVolume and [haiku_]kernel_emu.{h,cpp}.
- Added HaikuKernelNode, which wraps fs_vnode for the client FS.
The server is still quite a bit away from being buildable again.
