process group. This fixes bug #996.
* As a result, the process group stuff and wait_for_child() got much simpler;
get_death_entry() and update_wait_for_any() could go away completely.
* If a team goes away, all of its children are now "reparented" to the kernel team,
instead of the team's parent - this follows common implementations (and POSIX if
I understand it correctly), but not BeOS anymore. The OpenGroup Base says this
about this topic: "If a parent process terminates without waiting for all of its
child processes to terminate, the remaining child processes shall be assigned a
new parent process ID corresponding to an implementation-defined system process."
* We wait too long in wait_test_4 which at least puts us on par with Linux; see
comment in _user_setpgid().

broken (see bug #996), but less broken than Be's.
Also the Linux implementation is not perfect, as test 4 reveals: it waits for a
child with a certain process group, even if there is no child around anymore (because
the last child changed its process group. However, it will still return (and report
the correct error code) once this child exits.

ECHILD in case it doesn't. This fixes bug #995.
* Added a TODO item for solving bug #996.
* wait_for_child() did not release the team lock and restore interrupts in case
the child you wanted to wait for didn't exist...
* with child > 0, wait_for_child() will now check if its really a child of yours,
and not just in the same process group.

with PostMessage() in case the message queue is full.
Some notes:
* for synchronous replies, we don't use this mechanism yet, but it could be
extended to do that as well.
* the code looks so complicated because we need a way to access the looper's
queue without locking it (to prevent deadlocks); like Dano's solution, I've
abused BTokenSpace to store a BDirectMessageTarget with a BHandler.
* we also need to decouple the lifetime of a looper's queue from its target,
as we cannot lock the looper, and therefore, can't guarantee it stays valid
as long as we're accessing it outside of BLooper.
* init_clipboard() now needs to be done after the global constructors have
been called - since sending messages now needs gDefaultTokens to be initialized.
Since this is done per image, it shouldn't cause any troubles, though.
* some minor cleanup, removed unused _msg_cache_cleanup_() and friends.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19968 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Got rid of unused BLooper members
* renamed fTaskID to fThread
* Removed private and deprecated AddLooper()/RemoveLooper()/... stuff; BLooper is now
directly calling BLooperList methods.
* Got rid of extensive and useless comments
* Made a few TODOs more clear
* Merged InitData() and InitData(...) to _InitData(...)
* BLooper::Team() now uses BPrivate::current_team(), sTeamID is gone now.

update its looper thread.

at least mounting/unmounting seems to work. This fixes bug #191.
* Also changed the way how Tracker automatically mounts/unmounts volumes: it now
only differentiates between removable and fixed storage, not between initial
scan at boot, and periodical scans during runtime. Also removed all HFS stuff.

modes (background gets a slightly different color, but this might be an app_server

* Got rid of the TSwitchManager::IdleTime()/Touch() stuff.
* Key repetitions are now accepted in the switcher, only the first (tab) key repetition

Switcher now works as expected.
* Renamed TRoster::ActivateApp() to UpdateActiveApp(), as the app is already activated
at that point (the registrar only keeps track of it).
* BWindow::DispatchMessage() now calls the new BRoster::Private::UpdateActiveApp()
method when it receives a B_WINDOW_ACTIVATED message.
* Added BRoster::_UpdateActiveApp() which calls the new B_REG_UPDATE_ACTIVE_APP.
* Removed now unused B_REG_ACTIVATE_APP.

BSD's file utility) to identify text files.
* The translator now automatically decodes files based "be:encoding" (which can now
also be a string type attribute), as well as whatever file_ascmagic() recognizes.
IOW we can now finally read all text files we recognize as text files.
* Added an ioExtension to force a specific encoding for Translate() (called "be:encoding"
as well).
* Enlarged the read buffer to 32768 bytes (instead of just 2048).
* Now fails when reading/writing files >4GB in STXT format (which doesn't support those)
* Translate() now writes the "be:encoding" attribute in case it detected the encoding
itself.

two cache_refs - it needs to count the consumers of the lower cache to find
its actual number of references; the upper cache could still be in use by
someone else.
* There were several locking bugs in the VM code; since cache_ref::cache can
change, we must not access it without having the cache_ref locked.
* As a result, map_backing_store() now requires you to have the lock of the
store's cache_ref held.
* And therefore, some functions in vm_cache.c must no longer lock the cache_ref
on their own, but require the caller to have it locked already.
* Added the -s option to the cache/cache_ref KDL commands: it will only print
the requested structure, and not its counterpart (useful if accessing one
structure results in a page fault, as was possible previously).

* made BppForSpace() in DriverInterface.h inline to remove some warnings
* renamed driver source files to lower case.
* removed Be Inc. copyright from kernel driver as I couldn't see anything coming
from Be Inc. there - correct me if I was wrong, Eric.
* Minor other changes like added missing header guards.
* The README provided in the main directory is only included in the accelerant
directory.

waiting for in case it was interrupted; but that could easily lead the thread_exit()
function to access invalid memory (and thus, crash the kernel): since we could not
remove our death entry from the thread, we have to make sure the thread (which might
still run even if not in the thread hash anymore) will access our death entry as
long as it is valid. IOW we must wait for the thread to delete its exit semaphore,
even if we were interrupted before.

* The cache_ref's area list now also prints the owner of the area.
* Added "-p" option to "cache"/"cache_ref" that will show the pages of the cache; if you
omit it, it will now only present you a page counter.
* Nicer output for the commands above.
* Added "dl" to display memory in 64 bit values.

* send_signal_etc() (among others) used team::main_thread in an unsafe way; it is
possible for a team to be part of the team list and a group without having
a main thread very early in its creation process.
* Replaced most occurences of team->main_thread->id with team->id since the team
always inherits the ID of its main thread in Haiku for quite some time now.
* Minor cleanup.
