B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a
structure (thus breaking BeOS binary compatibility), containing a
counter which is incremented whenever a thread has to wait for the
spinlock.
* Added macros for spinlock initialization and access and changed
code using spinlocks accordingly. This breaks compilation for BeOS --
the macros should be defined in the respective compatibility wrappers.
* Added generic syscall to get the spinlock counters for the thread and
the team spinlocks.

pipes in the shell, though the semantics is a little different: The
second command is invoked whenever the first command has written a
complete line. The line is passed as last argument to the second
command. The new command flag B_KDEBUG_PIPE_FINAL_RERUN causes the
second command to be invoked again (with NULL argument) after the
first command is done.
* Added kprintf_unfiltered() and kputs_unfiltered() which bypass the
pipe mechanism and directly print to the bluescreen/serial output.
* Moved most commands from debug.cpp to the new
debug_builtin_commands.cpp.
* B_KDEBUG_DONT_PARSE_ARGUMENTS commands don't get an argument anymore,
if it would consist of white space only.
* Added new debugger command return value B_KDEBUG_ERROR, which
indicates that executing the command failed. This return code will
abort a complete pipe.
* Since debugger commands can nest (i.e. one command can invoke another
one) the setjmp()/longjmp() mechanism to restore the stack after a
page fault in a command needs more than one jump buffer.
* Added abort_debugger_command(), which longjmp()s out of the currently
executed command. This will also abort the current pipe.
* When pagination is enabled pressing "a" will abort the running command
(as opposed to "q" which only disables the blue screen output, but
lets the command continue).
* Added debugger commands:
- "grep" which can be used to filter output by pattern. Removed the
"filter" command and the underlying mechanism that did that before.
- "head" which prints only the first lines of output of another
command.
- "wc" counts lines, words, and characters of another command's
output.

regression that audio playback of multiple files was not "seamless" anymore.
Even video playback should be seamless, the remaining small glitch could be
a problem with buffer timeout if the switch takes too long.

the producer media nodes would access the suppliers in their own thread
without having any locks held, while the window could replace the suppliers.
I think since I delayed the deletion of the suppliers in the controllers, this
problem was only theoretical... but this is just more clean.

try B_YCbCr422 as the most widely supported format in case the codec
does not advertise.

install + one or more updates.

as it seems devfs should not take over ownership. The device is deleted
in republish_driver for legacy drivers before the call to devfs_unpublish_device
that in turn deletes the vnode. This looks generally suspicious to me as
the device pointer the devfs vnode may still use gets invalid for a certain
amount of time (until the node is unpublished). So maybe the devfs should
take ownership of the device afterall and it shouldn't be deleted by the
device_manager/legacy driver functions. Axel please review.
* Do not try to delete the IOScheduler for now as creating one is disabled
currently too.
This fixes the crash on rescans of legacy drivers as seen when unplugging
USB devices.

"interface"
* Complete reimplementation of the playback engine using Media Nodes:
- Seeking video files does not appear to lockup the playback anymore, but
works on a frame accurate level even for keyframe based streams. There is
currently a problem with certain container formats, the audio track reports
a "Device Seek Error" in certain conditions. In that case audio goes silent,
and can be restarted by going back to the beginnings of the stream.
- Video overlays are now supported.
- It would be possible to connect the output of the MediaPlayer to other
applications or dormant media nodes.
* Known regressions:
- The volume slider has currently no effect anymore.
- Switching the audio track during playback has a known race condition and
can crash the player.
- The new engine is not as "light weight" as the old one. I tagged the
previous implementation in tags/components/mediaplayer-engine-v1. It does
not seem to have any noticable effect though.

to give other windows the opportunity to mark the icon invalid before
recaching it.
* Since we currently update all app MIME types on first boot, over 400 messages
are generated, so that delay easily caused the message queue to get full.
* I've now reduced the wait to 10 ms, and also call BWindow::UpdateIfNeeded()
afterwards, which empties the message port, too. This fixes bug #2212.
* Note though, this should be handled completely different to make it really
work right.

Instead we only allow temporary caches to be merged. This remedies the
problem that after fork() + join() there remains a superfluous cache
layer for all RAM areas.
I haven't tested it, but this might improve the jam situation
memory-wise (huge heap is committed one less time), though it might
worsen it performance-wise (lots of heap pages are moved with every
merge).

concurent SendRequest() calls. Therefore it's probably a good idea to
