initialized with BFS, though. Handy for installing Haiku on a partition.

* Reworked the select support:
- The io_context additionally stores a table of lists of select_infos,
which enables it to deselect events of a pending select() when
closing a FD. This prevents a race condition potentially causing a
write to stale memory.
- The opaque selectsync* passed to FSs is now actually a select_info*.
This was necessary, since the FDs deselect() hook (unlike the
select() hook) doesn't take a "ref" argument and deselecting a
single info (e.g. caused by a premature close()) was not possible.
The select() hook's "ref" argument has become superfluous.
- It should now be relatively easy to implement a poll_on_steroids()
that can also wait for objects other than FDs (e.g. semaphores,
ports, threads etc.).
* Set/reset the signal mask in common_select(). This makes pselect()
work as required.
* Reorganized vfs_resize_fd_table().

select_close_test select()s a file descriptor that is closed a little
later by another thread.

characters first, and then falls back to take everything. fTrigger is now
uint32 and works with all unicode characters; unlike in BeOS, the
MenuTriggerTest application now works correctly in Haiku.
* fTriggerIndex is now a character position, not a byte position of the label;
this allows BMenuItem::DrawContent() to draw the trigger at the correct
position, even if there are multi-byte UTF-8 characters.
* The above fixed bug #1506; triggers are still not working, though.
* Rewrote Menu.h header.
* Renamed all private methods (that are not called by BWindow) to have the
underscore prefix.
* Removed unused methods.
* Some minor cleanup.

necessary because low memory handlers might need to wait for other services
while we need to make sure the page thief can always steal pages.
* Made the page thief more aggressive when memory is critical: added a third
run where it will also steal a small amount of active pages to keep things
going.
* The page thief did not maintain the cache's reference correctly in all
situations.

it doesn't make a difference, since they were looping anyway, but
select() would report read-availability incorrectly.

writers.
* Removed the optimization for piping data between two threads of the
same team. This greatly simplifies the code. It seems to me the case
is very uncommon; it could be added back later, though.
* Basically rewrote reading from and writing to the pipe:
- A blockable writer can now write more than what is currently
available in the ring buffer.
- Writing respects the PIPE_BUF non-interleaving limit, though our
headers don't seem to define PIPE_BUF anywhere.
- Unblock writers, when the last reader is gone and send those that
haven't written anything yet a SIGPIPE. Fixes bug #1476.
* Correctly implemented select() support. We were only notifying
writers. We manage two separate select sync pools per pipe now: one
for the reader end and one for the writer end.
* Reading/writing from the root dir does no longer end in KDL.

which allows this (before, most handlers were gone after boot).
* Added debugger command that dumps the low memory handlers.
* The slab allocator now registers its low memory handler with a higher
priority, so that it'll run before the potentially heavier ones.

this function.
* Added a new ReadWriteLock::TryLock() method.
* Renamed bfs_read_vnode() and bfs_release_vnode() to bfs_get_vnode() and
bfs_put_vnode() just like those functions are called in fs_interface.h.
* Fixed a warning in BPlusTree::_SplitNode().
