9b906ccf04 * You can now create the block cache in read-only mode (using an additional
parameter during construction).
* Doing so will now result in a kernel panic whenever your file system tries to
  write to a block.

c40fe37f0b * Reverted the changes r17693 made to vfs_get_vnode_cache(); instead, vm_create_vnode_cache()
will now grab a reference to the vnode as well if successful. This way, vfs_get_vnode_cache()
  now actually works how it should: it will now always grab a reference to the cache and
  its underlying vnode. This removes an extra reference to the vnode (and vm_cache) that
  got ignored before and prevented volumes to be unmounted (or file caches to be removed).
  Thanks to Korli for pointing this out.
* file_cache_create() is now aware of that extra vnode reference and releases it; unmounting
  volumes is now working again as it should.

be0e738496 * send_signal_etc() now handles a pid_t of -1 specially, but not yet really correct
(that was part of the problem of bug #702).
* Fixed send_signal_etc() when you called it with a pid_t of zero: the signals should
  go to all teams in the calling team's group, not only to the team (for -1, we do
  the same for now).
* Made team_get_process_group_locked() public, and rewrote send_signal_etc() to use
  it.

567f38888f kill_thread() and friends are supposed to check the passed in thread_id or else
some signals could go to some group when a negative value was passed in.
This actually fixes bug #702 where SoundPlay obviously does a kill_thread(-1)
at the end (which accidently killed all userspace applications, including the
input_server, app_server, ...).

other teams left in it. This closes bug #1.

26a9fcd6ab * set_alarm() now correctly returns the time left for the currently active
alarm, or 0 if there isn't any.
* setitimer() now also sets the previous timer values correctly, so that
  alarm() and ualarm() now return the correct values as well - this fixes
  the test fork_9-1 failing at alarm().

2b6a368811 wait_for_child() could eventually hang until another team exited (or forever if
it waited for a specific child), as B_RELEASE_ALL opened up a race condition between
looking for an existing death entry, and waiting for the dead children semaphore.
Now we're counting all waiting threads for teams and groups separately.

79dd3d935a * The parent/group dead semaphores are now released a bit earlier to make
wait_for_child() hanging less probable - there is a general problem with
  this code, though, as we need to have a dedicated free counter for the
  semaphore to remove all race conditions.
* Also, test fork_3-1 still sometimes fails because the thread is still
  available to the public for a short time, even after its death entry
  has been collected.
* Added a TODO in the code for these issues.

73a56f1bac * wait_for_child() (the backend to waitpid()) did not work correctly in case you
wanted to wait for a specific child; it always assumed you had specified WNOHANG.
  This fixes the bug the fork_3-1 and fork_4-1 test applications reported. 3-1 still
  sometimes fails, but that's a different problem (to be solved later).
* Also, it could return B_BAD_THREAD_ID instead of the expected ECHILD (for waitpid()).
* There was a race condition between testing for a thread, and checking its death
  entry.
* wait_for_child() can now be interrupted in case it has to wait.

a9fa017d82 map_backing_store() did not acquire a cache ref in case it created a private
mapping, but it connected the vm_cache objects, so if it failed later, and
thus called vm_cache_release_ref() the object could have been freed accidently.
Most uses of map_backing_store() explicetly acquired a cache_ref *after* the
call was successful, but _vm_map_file() did not do this.
_vm_map_file() might still not work correctly, though, need to have a closer
look at it.

974533ab5a * Fixed a big race condition that could leave threads waiting infinitely and
let them eat death stack entries: after setting the next thread state to
  THREAD_STATE_FREE_ON_RESCHED, interrupts were enabled again, which could
  cause the thread to be rescheduled before having called put_death_stack().
  This fixes bug #434.
* Note that the above change pretty much reverts revision 7865 that was supposed
  to fix interrupt problem on thread exit (patch by Jack Burton almost 2 years
  ago, that's how long this problem existed!).
* Made get_death_stack() and put_death_stack() symmetrical in that they don't
  change interrupts. Also pulled out rescheduling from put_death_stack[_and_reschedule]()
  and put it back into thread_exit2().
