uninitialized memory. Fixes a crash on boot with a preloaded settings file
present that wasn't used before the boot device was available (like the vm
settings file).

- initialize the time_base_frequency kernel arg (should be done in the bootloader though...). We will use MFP timer to support system_time(). At least try to.

the methods IsFile() and GetFilePath() to BDiskDevice, and
BDiskDeviceRoster::GetFileDeviceForPath().
* Added new syscalls to implement this functionality.
* Added new flag B_DISK_DEVICE_IS_FILE.
* Fixed wrong operator precedence assumption in the BDiskDevice class at
several places.
* Minor cleanup.

* When invalidating unused settings, we should remove the handle from the list
before freeing it, or else the settings list will be corrupted.
* We should protect the safemode settings against being removed, or else they
won't be availabe anymore after we mounted the boot device.

- remove dead ppc code
- add support for probing hardware registers the way linux does (early, hook with VBR to trap faults)
- detect MFPs this way.

This confused some USB card readers, that would stop working if you still
requested the geometry when they reported no media.
Note the case that the B_GET_MEDIA_STATUS fails (because it's not implemented or
an error occured) is still handeld in _GetMediaStatus() and then we still try to
get the geometry to check for media presence.
This should fix that some USB card readers wouldn't work and should also remove
the wrongly reported size in DriveSetup for CD drives that don't actually contain
a media.

* The stack_trace() command now also uses this call by default to give you
the arguments to all functions in a stack crawl (beware of templates for now,
though).
* Use the new option '-d' to disable the demangling. You can now also specify
'-d' in the "call" command which has the same meaning there.
* NULL pointers are now printed as "NULL", and NULL strings are printed as
well.

debugger add-on set a demangle hook, all modules under debugger/demangle/ are
now considered demangle modules.
* Added another function to the demangle module interface that gives you access
to the arguments.
* Implemented a demangling module for GCC2.
* The older demangling module is now called "gcc3+", but doesn't support
getting the arguments yet.
* The "call" KDL command is now using demangling to automatically show you
the arguments of a call from a stack crawl.
* Minor cleanup.

* Actually call prepare_sleep_state() instead of calling enter_sleep_state()
twice...
* Commented out disabling interrupts when calling enter_sleep_state(), as our
ACPI modules would then crash (needs memory & uses sems with interrupts
disabled). This way, it at least works on some hardware, including emulators
(as before).

case it has to call the file map translation hook again to fulfill the whole
request; it already handled the partial case correctly.
* This fixes an occasional "Value too large" error when accesssing fragmented
files.

r27530 - allow faults with ints disabled if there is a handler
r27648 - call the end-of-interrupt thread callback
r27718 - add <asm_defs.h>, not used yet
r27722 - register the commpage as image and symbols (but we don't use it yet)
- remove dupped call to thread_get_current_thread()
- use 16MB iospace for now, 4MB seems too small.

physical page in the page fault handler instead of mapping it first.

in struct stat.
* Instead, I followed Marcus' great idea and added a compatibility check in
the runtime loader: now, R5 binaries (also shared libraries) are detected,
and they get special versions for stat(), fstat(), and lstat() that return
the smaller stat struct.
* However, I've disabled (in src/system/libroot/posix/sys/stat.c) using the
larger stat field for now, as this breaks some of our optional packages.
So until we rebuild them all, this shouldn't be enabled.
* This should now also be used for BeOS compatibility in libnetwork.so.

subdirectories. Also moved the x86 kernel arch_string.S there.
* Moved memcpy.c from src/system/libroot/posix/string into the
arch/generic subdirectory.
* Dealt with the consequences of moving things around. Affected are also
the boot loader and runtime loader builds.
Adjust the m68k and ppc parts, too, but only the x86 build is tested.

arch_vm_aspace_swap().
* The x86 implementation does now maintain a bit mask per
vm_translation_map_arch_info indicating on which CPUs the address
space is active. This allows flush_tmap() to avoid ICI for user
address spaces when the team isn't currently running on any other CPU.
In this context ICI is relatively expensive, particularly since we map
most pages via vm_map_page() and therefore invoke flush_tmap() pretty
much for every single page.
This optimization speeds up a "hello world" compilation about 20% on
my machine (KDEBUG turned off, freshly booted), but interestingly it
has virtually no effect on the "-j2" haiku build time.

specified via a mask.
