(it didn't really work previously anyway). The only alignment really used seems
to be B_PAGE_SIZE, which happened to always work out before, because anything
larger would have been allocated using individual pages anyway. Since larger
bins are now available and with kernel heap leak checking enabled an allocation
of B_PAGE_SIZE with B_PAGE_SIZE alignment is actually a bit bigger than
B_PAGE_SIZE, it got into the 5KB bin, which didn't guarantee the alignment
anymore. This would have caused a tripple fault on boot when kernel heap leak
checking was enabled. The alignment is now taken into account when picking
the bin for the allocation. Added a more detailed TODO as to why this isn't
the best thing (wastes space) and how it could be changed if deemed necessary.

Implemented the needed fs API hooks to support identifying partitions
(so ReiserFS partitions appear in the Tracker Mount menu now).

serve, bin sizes and page size. This minimizes the amount of "large"
allocations made in heaps that don't have a bin for the allocation size
(combining multiple pages). This is desirable as such large allocations
are generally pretty inefficient, and also because it separates larger from
smaller allocations better, making the chance of a heap becoming empty higher.
For now there are three heap classes "small", "large" and "huge", with a
predefined set of bin sizes for each. This might need some finetuning later on.
Reduce the grow size to 4MB though as the allocations should now be spread
across heap classes which each grow on their own.

allows for dynamic (heap)page sizes. It's currently just set to B_PAGE_SIZE
but I'm expermienting with the creation of differently sized heaps that could
use dynamic page sizes with that.

the cancel, it wasn't actually done. This could bring a device out of sync in
the case timeouts actually happened (which shouldn't be a commen case).
Fixed that and increased the timeout to 2 seconds in favor of slower devices.
Might need some fine tuning later still.

Avoid unhandled event in the bluetooth_server

Fixed race conditions when a ServerApp or ServerWindow is created. The
reply to the client that the object has been created successfully was
sent in the thread creating it. Preempted at the wrong time (right after
writing the message to the port) could lead to the object's thread using
the link at the same time, which would screw up all subsequent
communication via that link.
This fixes the problem that mimeset would sometimes fail when building
Haiku in Haiku (can't find the ticket). It probably also fixes#2331,
and the bug that sometimes when a window is opened (Terminal, crash
alert, shutdown window, etc.) it would come up with huge width/height
and tiny other dimension (can't find the ticket).

* It's not yet complete, doesn't support some ext2 stuff (like files over 4 GB),
and might have some other bugs (I only tested it with a single 20 MB ext2
image).
* To have a read/write ext2 file system, it would probably make more sense to
port GNU sources (like ext2fs lib), and use that. But a small read-only ext2
file sytem doesn't hurt, I think, and I don't know if ext2fs lib would be
feasible for kernel use (porting the file system from Linux directly would
also be an alternative, but probably more work).

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.

correct, but it prevents a deadlock that could sometimes be seen right after
booting when the Terminal was supposed to draw the decorator buttons. It
doesn't seem to cause any problems with locking removed (the original drawing
code didn't lock either). Added a TODO to investigate and eventually fix that
though.

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.

SplayTree, additionally maintaining a singly-linked list, thus allowing
for efficient forward iteration.

straight all-static build, with only OpenSSL as dependency. Be sure to include
OpenSSH (and set a hostname) if you intend to use svn+ssh. Should work with
svn, svn+ssh, http and https. Feel free to replace with a proper dynamically
linked version once available.

* 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.

Grep declares it "working" when strerror_r returns a string, while POSIX says
it should return int (as we do). Don't know where this config define came from,
as we do not have any headers advertizing it wrongly. This fixes bug #2450.
