the newly found disk systems.
* _ScanPartition() now allows to restrict the disk systems to a predefined set.
* _ScanPartition() now even scans partitions that already have a disk system
assigned; if a better one is found, the existing one is replaced. It will
ignore mounted or partitions with children, though.
* KPartition now also stores the priority of the disk system assigned to it.

per cache.
* Changed the strategy vm_cache_acquire_page_cache_ref() uses to ensure
that the cache isn't deleted while trying to get a reference. Instead
of the global cache pages hash table lock, it holds the global cache
list lock now. We acquire + release this lock in delete_cache() after
removing all pages and just before deleting the object.
* Some small optimizations using the property that the cache's pages are
ordered, now (vm_cache_resize(), vm_page_write_modified_page_range(),
vm_page_schedule_write_page_range()).
* Replaced some code counting a cache's pages by simply using
vm_cache::page_count.

* Suggest growing when there are less than 10% free pages in the last heap.
Previously it would suggest growing when there were less than three free
pages, which wasn't really any good measure. In quite a few cases this could
have lead to too late growing and running out of heap space.
* Only panic when memory allocation fails while growing kernel heaps. Otherwise
just output a message and return NULL. Even this panic is not really
necessary and should be continueable, but for now I'd like to see if this
situation actually happens.

and returns an error, if that fails.
* Adjusted code using the classes accordingly. Replaced a few
InitCheck() methods in the network code by Init().

(and if it isn't used anymore).
* vnode_low_memory_handler() now just calls it this way, so it doesn't have
to use two passes anymore, and can always write back vnodes without having
the busy flag set.

a flattened argument/environment buffer now. This simplifies the work
for the kernel a bit, since it can just copy the buffer and check
whether it looks OK instead of messing around with individual strings.
The runtime loader also gets a flattened array.
* Set the maximum size of the arguments/environment buffer to 128 KB.
When more arguments are passed, we fail with a proper error code
(instead of just truncating the arguments as before).
* On exec*() the first argument was silently replaced by the given path
name, which is not correct.

it was done, which caused a race condition with the page fault code.

waiting for a heap grow.
* Use that nogrow version in the VM code to avoid a deadlock with the address
space lock when a grow operation would try to create an area while a malloc
happened from such a function in the VM.
* When waiting for a grow to happen, notify the waiting thread from the grower
also if it failed to allocate a new heap. Otherwise a thread would just sit
there and wait until another thread requested growing too and that one
succeeded (or just forever in the worst case).
* Make the dedicated grow heap growable too. If the current grow heaps run low
on memory it will instruct the grower to allocate a new grow heap. This
reduces the likelyhood of running out of memory with no way to grow to a
minimum. As the growing is done asynchronously it is still possible to
happen, but it is highly unlikely as the grow heap is solely used to
allocate memory in the process of creating new heap areas and it will even
try using normal public memory if the dedicated memory has run out.
* Reduced the dedicated grow heap from 2 to 1MB. As it can now grow itself, it
doesn't need to last so long.
* Extract heap creation into it's own function that does area creation and heap
attach and use this function for growing normal and grow heaps.
