Introduced a gBootFrameStack that is used until the first thread structure
is available - this allows stack crawls and useful register dumps during
early startup. Could also be solved differently by making sure there is
always a thread structure installed in %dr3 (ie. the boot thread would
get a static thread structure instead of a static iframe stack only).
This might be a better solution as i386_handle_trap() would no longer
need to check for an existing thread structure.

Moved ptentry/pdentry to arch_vm_translation_map.c and renamed them to
page_table_entry and page_directory_entry.
Fixed a race condition that happened when memory was remapped (which
can currently happen because lock_memory() does not work correctly, and
there might be other conditions as well, like certain vm_store fault
handlers). Now, page table and directory entries are updated atomically.

is only accepted when there is at least one valid partition in it.
Before, the module would accept even the BFS boot loader which is now less
likely (IOW you can now boot with Bochs again).
Also, if there was one invalid partition, the partitions that come after
it are no longer ignored.

Now, F12 will get you into the kernel debugger. The escape key was somehow not
too happy with vim before :))

It cannot be called with interrupts off, and is likely to fail in the debugger;
arch_cpu_shutdown() reboots the machine directly which is what we want here.

The frame buffer console now creates such a boot item to give a potential
VESA driver access to the boot frame buffer configuration.

- we must not use static C++ locks: the heap is initialized before the
global constructors are called which means that our sLockList was
initialized twice, and lost all locks added inbetween
- *but* the lock implementation was completely wrong anyway: Hoard used
to allocate superblocks, but it never freed them - instead, their memory
was recycled when their time came. That caused semaphores to be in fact
thrown away, but also corrupted the lock list
- I've now implemented the locks like they are implemented in the other
architectures supported by Hoard: via a spinning (busy waiting) lock.

- vfs_exec_io_context() did not close descriptors
- no variant of dup() did increment the open_count
This allows "VARIABLE=`command`" bash lines to work again.

partitioning system module relies on it, otherwise extended
partitions won't be recognized.
* Be a little less lazy and do the priority partition recognition,
i.e. all partitioning systems are asked to identify a partition and
the one that believes it can handle the partition best, wins the pot.

* We apparently cannot use constants like kPartitionTypeIntelExtended
in static array initializers in the kernel.
* Fixed misunderstanding between Axel (boot loader) and me (Intel
partitioning system module) how to deal with the cookie the
identify() hook returns. We switch to a someone cleaner method by
always invoking free_identify_cookie() for it, even if it were passed
to scan(). Since we want to keep the cookie, we add a reference
counter to it.
This should fix a couple of issues with recognizing the boot partition.
