system/boot: Add support for multiple bootloaders

disk device manager: Remove obsolete include path

virtualdrive hasn't been used for a long time. Should help with #12162.

* Got rid of the duplicated functionalities provided by RWLocker.cpp, and
Locker.cpp.
* The services are now using recursive_locks, and rw_locks instead.

* <DiskDeviceTypes.h>: Removed kPartitionTypeIntel{Primary,Logical} constants.
* Added new header headers/private/system/disk_device_types.h, which defines
the <DiskDeviceTypes.h> constants as macros and which can be used where the
constants cannot be used. The constants are defined using the macros, so now
there's only one place where the string literals should be specified.
* Use the macros in the partitioning systems. I was too lazy to also adjust the
file systems -- most of them seem to hard-code the string literal yet.

* Removed -Wno-unused from all KernelMergeObjects in kernel Jamfiles.
* Fixed most of the warnings resulting from that by removing actually not used
variables or moving declaration into the #IF. Left unused functions there
though, as I wouldn't know if they are supposed to be used again.
* Fixed two statements with no effect (clamping to MAX_ANCILLARY_DATA_LEN in
socket.cpp and unsetting fCounterSem in MessagingService.cpp).
* Some style cleanups.

Folded KPhysicalPartition into KPartition. Removed the notion of shadow
partitions from the disk device manager.

* Moved partition scanning back to KDiskDeviceManager. ATM only
synchronous scanning is supported.
* Removed the disk device job support from the disk device manager.
* K{Disk,File,Partitioning}System:
- Remove querying and validation methods.
- Commented out the modification methods until their fate is decided.
* Removed obsolete _user_get_partitionable_spaces().

Addition of write support to the disk device manager. Courtesy of Tomas

* Introduced new build system variables
{HAIKU,HOST,TARGET}_KERNEL_PIC_{CC,LINK}FLAGS which define the
compiler/linker flags specifying the kind of position independence
the kernel shall have. For x86 we had and still have -fno-pic, but the
PPC kernel has -fPIE (position independent executable) now, as we
need to relocate it.
* The boot loader relocates the kernel now. Mostly copied the relocation
code from the kernel ELF loader. Almost completely rewrote the PPC
specific relocation code, though. It's more correct and more complete now
(some things are still missing though).
* Added boot platform awareness to the kernel. Moved the generic
Open Firmware code (openfirmware.c/h) from the boot loader to the kernel.
* The kernel PPC serial debug output is sent to the console for the time
being.
* The PPC boot loader counts the CPUs now and allocates the kernel stacks
(made OF device iteration a bit more flexible on the way -- the search
can be restricted to subtree). Furthermore we really enter the kernel...
(Yay! :-) ... and crash in the first dprintf() (in the atomic_set()
called by acquire_spinlock()). kprintf() works, though.

This should fix the build after all the kernel/system renaming.
If anything is still broken (and was not before :)), please shout.
