small to hold the information for the requested I/O size.
* get_file_map() returned B_BUFFER_OVERFLOW already in case the array
was exactly as large as needed.
* read_chunk_into_cache() and write_chunk_to_cache() will no longer
override their local "size" variable.

* Minor cleanup (like removing the extra blank line between the copyright and the
header guard).

sets a fault handler, so that an invalid memory access while executing
the command (address typos always do the trick :-) won't result in
another KDL session on top of the current one, which wouldn't even be
"cont"able.
All pieces of code setting a fault handler do now save and reset the
previous one, so that e.g. a user_memcpy() in a debugger command doesn't
disturb the mechanism.

introduced a locking problem, since vm_page_allocate_page() is invoked
with a locked cache. I guess I have to rethink the design. :-/

unload_kernel_add_on(). The former one could lead to deadlocks with
load_kernel_add_on() (e.g. occasionally the boot process would hang).

The supported devices list passed to the usb bus manager is now automagically generated from the other list so it's always correct (it was already out of sync).

* Added a few comments.
* Simplified the nested while loops by dropping the special handling for the
first iovec and restructuring the innermost loop. This also rules out
the possibility of a zero-length temporary vec. IMHO the readability
has improved quite a bit (YMMV :-). Hopefully without introducing new
bugs; please review!
* Corrected computation of totalSize in case less than size has been
read/written.
* Also set *_numBytes in case all fileVecs have been processed. Only
relevant in case the request extends beyond the end of file.

solves the problem that app_server uses the wrong version of
the class

I'm just eager to close this crucial bug, which Ingo kindly
tracked down

filling them which could have written over the stack, and their iovec length
was set for the wrong iovec, potentially clobbering any memory.
* The first tempVec was usually empty, anyway, as the wrong iovec was chosen
to start from (usually one too early).
* The tempVec loop is now repeated until the whole fileVec is completed.
* Minor cleanup.

in.
* New debugger command "find_page", which searches all page queues to
find out, which one a page is actually in.
* Solved nasty race condition between the page scrubber and
vm_page_allocate_page_run(): The page scrubber didn't mark the pages
it was processing busy, so that vm_page_allocate_page_run() could claim
them in the meantime. They would end up in the clear pages queue,
although being assigned to a cache at the same time. This should
finally solve bug #1056.

being merged in vm_cache_remove_consumer(), fault_find_page() tried again
with the current vm_cache_ref, but didn't realize it might have had inserted
a busy page in this cache already.
This fixes a deadlock, as this page would never get unbusy again.
