as the other node operations.
* Differentiate between data and metadata modification, so that changes to
attributes or stat fields (other than size) dont't prevent direct IO relay.
* Suppress child finish notifications when sending subrequests to the
underlaying filesystem. Otherwise the request can be gone by the time we
try to complete it.
* Fix offsets used for IORequest::CopyData().
* Some refactoring.
* Added locking.
With that a write_overlay can be put on attribute enabled filesystems to either
make them writeable or snapshot them. This allows for example for a working
BFS based LiveCD.

This allows for synchronous uses where subrequests are forked off and waited on.

Increased the scrollers size from 10 to 12, since at high resolutions,
they're really too small.

Otherwise the focus cannot be changed to another window. In one case this could
have a severe sideeffect: When a window is quit it is hidden to remove focus and
remove it from screen. If this didn't work due to the focus lock, the fFocus
member would become a stale pointer after the window was quit and deleted. The
app_server would crash or corrupt memory on the next focus change. Easily seen
when moderately quickly clicking away a few alert windows.

On detaching the views remove themselves from the app local token space. Since
the ServerApp only waits for all ServerWindows to be removed from the window
list and not for their actual destruction, it can happen that the ServerApp is
deleted before the window destruction and hence the view detaching has finished.
The views would then access a stale ServerApp pointer and try to remove their
token from the deleted token space. To avoid that we set the ServerApp pointer
to NULL when the window is removed from the app (as after that the app can be
gone any time) and check for that case when detaching.

only some sub requests worked. Previously we would have simply canceled all
of the subrequests in the loop because we cancel after the first error.

* An off by one error prevented the very last block of a device to be accessed
through IO.
* In case of error the request wasn't notified causing anyone (the page writer
for example) to wait forever for the request to complete.

by writing them into our buffers and directly satisfy read requests by copying
our buffers, filling any gaps by spawning off subrequests to the underlaying
filesystem.

concerned by it as it does not do file data, it simply passes the hook through.
In the write_overlay case we check for write operations and for modified nodes.
In both cases we return B_NOT_SUPPORTED which will cause a fallback to
synchronous IO. The main problem with the fallback is not that it is synchronous
but that the physical buffers of the request will be mapped and filled page
wise, which makes it slow for various reasons. In any case with this setup all
reads to write_overlay that can go through unmodified now do. This should speed
up CD boot as there is no physical to virtual translation overhead and no limit
to page wise reads. In the best case it should now read 256 blocks at the time
instead of always falling back to 2. My tests show no side effects on creating,
writing or partially modifying nodes so far.

capabilities to aid in debugging memory corruption issues.
It does:
* Initialize memory to 0xcc to help turn up use of uninitialized memory
* Set freed memory to 0xdeadbeef to help find accesses of freed memory
* Use the paranoid heap validation to turn up many cases of memory corruption
* Use a simplistic wall check to turn up memory overwrites past allocations
* Take extra steps to validate freed addresses to turn up misaligned frees
It has an interface to en-/disable paranoid validation and to start/stop regular
wall checking. Both are currently just enabled. At a later stage a debug version
of libroot could be used by an application and the checks enabled at will. Note
that due to the paranoid validation and the suboptimal locking this allocator
will perform horribly. Still to find memory corruption issues in the system or
also in your applications it can be helpful to build your installation with it
turned on. To enable it you currently need to edit the Jamfile to sub-include
the malloc_debug instead of the malloc directory.

Updated to use all the new alpha1 packages. I have not yet done throughrough
testing myself. I figured that trunk should also use the newest packages.

for the page list but not the area one. Since multiple pages can be allocated
at once, even an area that is not at the top of the list can become empty. In
such a case the area list would previously have lost entries. Also because
we can remove more than one page from any area, not just the top one, we may
need to move forward in the list so that it stays ordered by free pages.
