needed. I've added MediaPlugin* fields to Reader and Decoder plugin classes
which are set when the PluginManager hands out new instances. This way the
manager knows what plugin created the Decoder or Reader instance in the
Destroy*() methods and can decrease the reference count accordingly. Also added
some FBC stuffing to Decoder and Reader. All media plugins need to be recompiled,
in case anyone has some outside the Haiku tree.

boot device is actually read-only (even if it's using the write overlay).
* Do not create a swap file on a read-only device - this would really be a
stupid use of the write overlay (just saw this happening on an older
machine).
* Made swap_file_{add|delete}() take a const char* path - there was no reason
this was writable, and this also avoids casting away the const when adding
the default swap file.
* Minor cleanup.

pools (deleting a pool frees all memory allocated in it). The heap should
eventually be used for all commands that need temporary storage too large for
the stack instead of each using its own static buffer.

- While walking down the cache chain, we keep all upper caches locked.
- When we have to unlock -- when waiting for a busy page or reading a page in
-- we unlock completely, including the address space, and restart
vm_soft_fault().
- Folded fault_get_page() and fault_find_page() into one.
This simplifies and improves things considerably:
- We no longer need dummy pages.
- We no longer need vm_area::no_cache_change.
- #2710 is fixed, since we no longer hold the address space lock while
waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
is already mapped at the address. If it is already our page, we just change
its protection. If not, we unmap it first. Fixes race conditions when multiple
threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
vm_translation_map::protect() call.

gcc could apparently assume that the register assigned to the one in the
clobber list would keep its value (as can be observed when disassembling
add_debugger_command_etc()).
Using a dummy output register works around the problem and also avoids the
unnecessary initialization of the register.
Comments explaining the mystery welcome.

the syscall. Anything beyond st_mtim was therefore not filled in. Fixes
the incorrectly shown creation times in Tracker.
* The BStatable::GetStat() solution was not sufficient yet. We still have to
provide the old GetStat() symbol for BNode and BEntry, since those could be
used by old applications/libraries. We also still have to implement the old
GetStat() slots in the derived classes, but don't need to implement it in
the base class (was purely virtual before and is private now).
* The old BStatable::_OhSoStatable1() slot function was not implemented
correctly. Calling the virtual function at the vtable slot obviously results
in an infinite recursion. The correct implementation would make use of the
Perform() method, but Be didn't provide one for BStatable, so we have to use
the old GetStat() method. Fixed#3960.

* Copied ide_adapter.h as ata_adapter.h in attempt to further
separate the two stacks.
* Continued renaming stuff in drivers/bus/ATA.h
* Make all the busses/ata drivers include the new headers,
specifically ata_types.h, ata_adapter.h and bus/ATA.h,
they were all including ide_types and bus/IDE.h still
* Some renaming of global variables for coding style consistency
* Removed the promise driver from the build, it's not used on the
image and I don't believe it compiled even for the old IDE stack.
* There is no more Command Queueing in the new ATA stack, so I
removed the capability indication from the busses/ata drivers
and ata_adapter.h.
The new ATA stack still boots fine on my computer and I proof-read
the diff like two times. Basically, this was a careful search&replace
job only. The only things I am not sure about is renaming some
publishing related strings, but it seems to all work fine.

* Implemented a way to do asynchronous pre-fetching when mapping files.
* There are slight code duplications in some places that could benefit
from cleaning up, but nothing too bad.
* Implementing smarter ways to trigger prefetching and more analysis of
the situations in the kernel would be nice. Currently up to 10 MB
of every mapped file are pre-fetched without further analysis.
* The speed improvement is nice for certain operations. On our test
system (real hardware), Firefox took 9 seconds from being launched
to display a window. Now it takes 5 seconds. Both measurements
right after booting. The same system took 35 seconds from launching
Haiku in the GRUB menu to displaying the Tracker desktop background
image. Now it takes 27 seconds.
* We didn't have the chance to check out the effects of this on the
CD boot, but potentially, they could speed it up a lot.

socket could be acquired, ie. when its reference count is 0, it cannot be

* The TCP EndpointManager now checks the return value of acquire_socket(), and
only returns the endpoint if that succeeded.

- Moved scheduler listening interface to <listeners.h> and added more
convenient to use templatized notification functions.
- Added a listener mechanism for the wait objects (semaphores, condition
variables, mutex, rw_lock).
* system profiler:
- Hopefully fixed locking issues related to notifying the profiler thread
for good. We still had an inconsistent locking order, since the scheduler
notification callbacks are invoked with the thread lock held and have to
acquire the object lock then, while the other callbacks acquired the object
lock first and as a side effect of ConditionVariable::NotifyOne() acquired
the thread lock. Now we make sure the object lock is the innermost lock.
- Track the number of dropped events due to a full buffer.
_user_system_profiler_next_buffer() returns this count now.
- When scheduling profiling events are requested also listen to wait objects
and generate the respective profiling events. We send those events lazily
and cache the infos to avoid resending an event for the same wait object.
- When starting profiling we do now generate "thread scheduled" events for
the already running threads.
- _user_system_profiler_start(): Check whether the parameters pointer is a
userland address at all.
- The system_profiler_team_added event does now also contain the team's name.
* Added a sem_get_name_unsafe() returning a semaphore's name. It is "unsafe",
since the caller has to ensure that the semaphore exists and continues to
exist as long as the returned name is used.
* Adjusted the "profile" and "scheduling_recorder" according to the system
profiling changes. The latter prints the number of dropped events, now.

ActivityMonitor wont stall anymore when initiating the drag. (On the desktop, Tracker's mouse
tracking still busy loops sometimes, that's next on my list).
I had asynchronous long click detection (one button mouse support) in it but decided to get rid of
it, it adds unneeded complexity in the code and is even getting in your way sometimes (ex: now you can
take your time to drag the dragger, you wont be interrupted). If we want to reimplement that
someday it should be done system wide anyway (only Tracker and replicants have that 'feature'
AFAIK).

the protocoll less prone to errors, reduces possible points of failure and
most importantly, reduces the number of function calls to the link API.
I only know the numbers for StrokeLine(), which I tested via the Benchmark
test app. With this change, drawing random colored and positioned lines
actually doubled in speed. On the BView side, the calls to
ServerLink::Attach() only halfed, while on the app_server side, the number
of calls to ServerLink::Read() is now 1/4th. It will also be worth
investigating why the link stuff is so slow at all. I also optimized
BView::DrawString() a lot in this change, but I don't have any numbers
yet. Some other commands which used multiple Attach()/Read() calls were
also optimized, at least the most important ones. Begin/EndLineArray() was
also pretty bad on the app_server side.
