additional partition_data* child parameter now.
* _user_get_partitionable_spaces() doesn't need to copy the buffer into
the kernel, since it is no input parameter. It also copies back the
actual partitionable spaces count on error, now -- B_BUFFER_OVERFLOW
is returned when the buffer was too small, but then the count must be
returned too.
* Fixed several instances of syscall implementations that unloaded a disk
system, although they didn't load it in the first place. This screwed
up the load count with undesirable consequences.
* _user_create_child_partition() would set the size to the supplied
offset.
* Fixed broken loop in KPhysicalPartition::CreateShadowPartition().
* KPartition::RemoveChild() notified the listeners about the wrong
event.
* Intel partitioning module:
- The *_get_partitionable_spaces() correctly return B_BUFFER_OVERFLOW
now, if the supplied buffer is too small.
- Implemented a part of pm_shadow_changed(), which creates and updates
the PartitionMap, so that the validate_*() hooks have a chance to
work at all.

mjw for the hint. Fixes bug #1516.
* Changed _{kern,user}_create_symlink() to no longer check the supplied
link string. BeOS seems to do that, but this is not standard
conforming. The previous implementation even used the path processed
by check_path(), which would potentially have appended a ".".
* Some style cleanup.

system initialize() hooks. It's often the only info about the
partition one needs and thus locking the partition just to get it is
no longer necessary.
* intel partitioning system:
- Removed passing around block sizes. We require 512 byte sectors
anyway. In fact using the parent partition's block size was even
wrong.
- Simplified writing the partition map sector.
- Simplified and corrected the partition map initialization.
- We don't fail identifying a partition anymore, if the partition map
contains no partitions. We would never identify a freshly
initialized partition map before.
- Made pm_identify() more intelligent: It determines the priority to
return depending on whether the partition is the device itself and
whether we have recognized child partitions.

* RequestOwner was removing the wrong request from the second queue,
which could cause the list structure to become invalid and result in
bug #1526.
* In the writer loops we do now call tty_notify_if_available() when
we're potentially going to wait and had written something before, so
that a waiting reader will be woken up also when we write more bytes
than fit into the ring buffer.

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.

* In select_fd(): First get the file descriptor, then check whether any
events have to be selected at all. This has the advantage that the
caller can interpret an error return code as invalid FD. Consequently
common_poll() no longer checks FD validity separately -- this was a
race condition.
* common_poll() always selects POLLERR and POLLHUP now, which it has to
do according to the specs.

* Reworked the select support:
- The io_context additionally stores a table of lists of select_infos,
which enables it to deselect events of a pending select() when
closing a FD. This prevents a race condition potentially causing a
write to stale memory.
- The opaque selectsync* passed to FSs is now actually a select_info*.
This was necessary, since the FDs deselect() hook (unlike the
select() hook) doesn't take a "ref" argument and deselecting a
single info (e.g. caused by a premature close()) was not possible.
The select() hook's "ref" argument has become superfluous.
- It should now be relatively easy to implement a poll_on_steroids()
that can also wait for objects other than FDs (e.g. semaphores,
ports, threads etc.).
* Set/reset the signal mask in common_select(). This makes pselect()
work as required.
* Reorganized vfs_resize_fd_table().

* Removed the optimization for piping data between two threads of the
same team. This greatly simplifies the code. It seems to me the case
is very uncommon; it could be added back later, though.
* Basically rewrote reading from and writing to the pipe:
- A blockable writer can now write more than what is currently
available in the ring buffer.
- Writing respects the PIPE_BUF non-interleaving limit, though our
headers don't seem to define PIPE_BUF anywhere.
- Unblock writers, when the last reader is gone and send those that
haven't written anything yet a SIGPIPE. Fixes bug #1476.
* Correctly implemented select() support. We were only notifying
writers. We manage two separate select sync pools per pipe now: one
for the reader end and one for the writer end.
* Reading/writing from the root dir does no longer end in KDL.
