a message to the (currently hardcoded) desktop message looper. The desktop then
does mark the whole screen dirty which causes a full redraw.
Since interrupts need to be enabled I went with an asynchronous thread and
releasing a request sem in the add-ons' exit hook.
Added the add-on to the image as it shouldn't hurt to have it for now.

* our flock::l_len was inclusive, while it's exclusive (the last byte locked
is (l_start - 1 + l_len) not just (l_start + l_len).
* F_UNLCK removes all locks of the calling process that are within the specified
region - existing locks might also cut or divided.
* Apparently, a single team can lock the same region as often as it wants.
* advisory_locking is now using a DoublyLinkedList instead of its C counterpart.
* advisory_lock now has start + end fields, instead of offset + len, it's
handier this way.

* It's a while since I wrote this code, and I don't remember why I don't
always "set the configuration". Appearantly on BeOS and ZETA, the
active configuration was not yet set on the device when the driver examined
it, but on Haiku it is. The special control command which puts a tablet
into tablet mode is then not executed. I simply commented out this check
(always set the configuration) and now my Wacom Intuos 2 is working fine
in Haiku.

from the input_server implementation to create a log file.
* DeviceReader already provided the data byte count, since this is a USB
only Wacom driver, we can simply use the max_packet_size from the endpoint
descriptor. Changed TabledDevice accordingly to use the already existing
DeviceReader::MaxPacketSize().
* Reworked DeviceReader::ReadData(). Renamed variables for clarity and
removed the restriction to read exactly the requested ammount of bytes,
reading more than the "header" (which contains vendor id, product id
and max packet size) is already considered a successful read.
* Refactored TabledDevice::poll_usb_device().

to publish anymore (ie. existing devices will be unpublished in this case).
* republish_driver() now also calls load_driver() in case the driver is not

* publish_device() and unpublish_node() now maintain the new
driver_entry::devices_published field, so we always know how many devices

This eliminates the edge case where the grow thread would not be able to create
a new area because no memory could be allocated for the allocation of the area.
As this case cannot happen anymore, it is also not possible to deadlock in
memalign. Therefore the timeout (which would only have prevented the deadlock
but wouldn't have solved the edge case anyway) has been removed too.
Add options to dump the dedicated grow heap and to only print the current heap
count to the "heap" debugger command.

but there's a special handling for 0 us relative timeouts. Syscalls
usually return B_WOULD_BLOCK instead of B_TIMED_OUT in this case, and
callers might explicitely check for it. Hence we don't convert 0 us
timeouts anymore. gdb works again.

aren't tested yet.

* Added syscall restart support for connect(), accept(), send(), recv(),
which are implemented via ioctl()s. The actual restart support is done
in the net stack driver's ioctl() hook. Lower layers need to correctly
deal with socket timeouts, though, for which the stack module provides
support functions.
* TCPEndpoint::_WaitForEstablished() does abort now when an error
occurred earlier, so that trying to connect to an unused port fails
immediately, as it should.
* Fixed and refactored TCP connection reset handling. The new
TCPEndpoint::_HandleReset() does the job. Got rid of
TCPEndpoint::fError.
* Fixed sequence numbers for SYNC/FINI packets.
* The former two fix the problem that connections wouldn't be closed
correctly and could even be reused when trying to connect again (as
was reproducible with svnserve + svn).
* Some style cleanup in CPEndpoint.h.

* Implemented automatic syscall restarts:
- A syscall can indicate that it has been interrupted and can be
restarted by setting a respective bit in thread::flags. It can
store parameters it wants to be preserved for the restart in
thread::syscall_restart::parameters. Another thread::flags bit
indicates whether it has been restarted.
- handle_signals() clears the restart flag, if the handled signal
has a handler function installed and SA_RESTART is not set. Another
thread flag (THREAD_FLAGS_DONT_RESTART_SYSCALL) can prevent syscalls
from being restarted, even if they could be (not used yet, but we
might want to use it in resume_thread(), so that we stay
behaviorally compatible with BeOS).
- The architecture specific syscall handler restarts the syscall, if
the restart flag is set. Implemented for x86 only.
- Added some support functions in the private <syscall_restart.h> to
simplify the syscall restart code in the syscalls.
- Adjusted all syscalls that can potentially be restarted accordingly.
- _user_ioctl() sets new thread flag THREAD_FLAGS_IOCTL_SYSCALL while
calling the underlying FS's/driver's hook, so that syscall restarts
can also be supported there.
* thread_at_kernel_exit() invokes handle_signals() in a loop now, as
long as the latter indicates that the thread shall be suspended, so
that after waking up signals received in the meantime will be handled
before the thread returns to userland. Adjusted handle_signals()
accordingly -- when encountering a suspending signal we don't check
for further signals.
* Fixed sigsuspend(): Suspending the thread and rescheduling doesn't
result in the correct behavior. Instead we employ a temporary
condition variable and interruptably wait on it. The POSIX test
suite test passes, now.
* Made the switch_sem[_etc]() behavior on interruption consistent.
Depending on when the signal arrived (before the call or when already
waiting) the first semaphore would or wouldn't be released. Now we
consistently release it.
* Refactored _user_{read,write}[v]() syscalls. Use a common function for
either pair. The iovec version doesn't fail anymore, if anything could
be read/written at all. It also checks whether a complete vector
could be read/written, so that we won't skip data, if the underlying
FS/driver couldn't read/write more ATM.
* Some refactoring in the x86 syscall handler: The int 99 and sysenter
handlers use a common subroutine to avoid code duplication.
