b349aae941 Should have been part of r37678. io_request_is_vip() support.

83f46ed6ab file_cache_write() can get a NULL buffer and still a size != 0, which the
request handling wasn't taking into account.

9d3442dff1 Haiku defines B_BEOS_VERSION_5, so the code didn't work as intended. On Haiku,
we want to define closesocket() as close().

5147963dcd headers/private/kernel/util/OpenHashTable.h, Hugo's version, is a bit nicer than
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.

e66cd9d71b * For every request to userland we also send the team/thread/user/group ID of
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.

3cf43c2651 Removed the fs_vnode_ops::create_dir() parameter for returning the ID of the
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.

4649fe05ef * Haiku kernel interface emulation: Retrieve the capabilities for each vnode.
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.

b19ee1e164 * Port:
- 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.

60f4376e26 * Removed the unused Port::SendAndReceive().
* 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.

7c1ffcb9ec * The nature of asynchronous I/O is to be asynchronous. So we can't store
an on-stack structure for the request in a hash table when forwarding the
  io() hook. Create a new object (HaikuKernelIORequest) instead and store it
  in a hash table in HaikuKernelFileSystem.
* Some work on the userland side of do_iterative_fd_io().
* Added some missing requests in UserlandFSUtil::is_{kernel,userland}_request().

2f1f4f54d6 * Renamed UserlandFSServer to userlandfs_server. It is expected to live in
/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.

cdebdeb0aa Some more work towards adjusting the UserlandFS to the current FS interface:
* 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.

2bcdce290b First work towards adjusting the UserlandFS to the changed FS API. The

asynchronous I/O, and FS layers aren't supported yet. The userland code is
still completely out of sync and won't even compile.

636bfc08ae * Renamed fs/vfs_select.cpp to wait_for_objects.cpp and got rid of
vfs_select.h, respectively moved most of it into the new kernel
  private header wait_for_objects.h.
* Added new experimental API functions wait_for_objects[_etc](). They
  work pretty much like poll(), but also for semaphores, ports, and
  threads.
* Removed the "ref" parameter from notify_select_events() and the
  select_sync_pool functions as well as from fd_ops::fd_[de]select(). It
  is no longer needed. The FS interface select() hook still has it,
  though -- the VFS will always pass 0.
* de]select_fd() take a select_info* instead of a select_sync* + ref
  pair, now. Added respective functions for semaphores, ports, and
  threads.

ed07b9c7e3 The last missing hooks -- get_vnode_name(), write_attr_stat() and

27810ccf5e Added the last useful features I dare imagine: A Lock() method and the
possibility to initialize the AutoLocker without locking the object even
if it is unlocked yet. Especially in loops Lock()/Unlock() come handy
when an otherwise constantly hold lock needs to be unlocked for a short
time.

I suppose we should move the kernel utils AutoLocker implementation
to headers/private/shared, and drop the less powerful ObjectLocker.

4e0e80ed6c We analyze a client FS's capabilities -- i.e. which hooks it provides or

  and notify_listener() now. Mapped them in the BeOS kernel emulation
  accordingly. RamFS node monitoring seems to work now.

042eb16896 * More debug output in the kernel module.
* Made publish_vnode() available in userland. For old style FS add-ons
  publish_vnode() is used when they request a new_vnode(). The semantics
  of new_vnode() changed considerably in Haiku, but publish_vnode()
  seems to do pretty much what the old new_vnode() did.
* The UserlandFS hosted RamFS begins to work under Haiku. It runs pretty
  soon out of memory though (under vmware with 256 MB) and node
  monitoring is broken ATM.

617ed3e4a9 Implemented the new attribute open/close/... FS hooks. The mapping to the
old interface is completely done in userland ATM.

It becomes more and more obvious that we probably need to provide
the kernel add-on with a bit more information about what the client FS
interface supports in the first place, so we can save unnecessary trips to
the userland. Opening/closing attributes for a FS using the old style
interface could be handled completely in the kernel add-on, for instance
(even if we lose a bit of accuracy wrt to open modes etc.).

c10705cbda We do now provide the BeOS style FS add-ons with the kernel interface they
need via library libuserlandfs_beos_kernel.so. Fine-tuned the legacy headers
so they can by used by the the kernel interface emulation code as well as by
the add-ons. This is actually a bit hacky, since we build everything in the
Haiku build environment and thus mix these old headers and Haiku's.
