* Generalized address checks. The debugger can now also read the commpage.
* Added new syscall _kern_get_thread_cpu_state() to get the CPU state of a
not running thread. Introduced arch_get_thread_debug_cpu_state() for that
purpose, which is only implemented for x86 ATM (uses the new
i386_get_thread_user_iframe()).
* Don't allow a debugger to change a thread's "esp" anymore. That's the esp
register in the kernel. "user_esp" can still be changed.
* Generally set RF (resume flag) in eflags in interrupt handlers, not only
after a instruction breakpoint debug exception. This should prevent
breakpoints from being triggered more than once (e.g. when the breakpoint is
on an instruction that can cause a page fault). I still saw those with bdb
in VMware, but that might be a VMware bug.

needed. I've added MediaPlugin* fields to Reader and Decoder plugin classes
which are set when the PluginManager hands out new instances. This way the
manager knows what plugin created the Decoder or Reader instance in the
Destroy*() methods and can decrease the reference count accordingly. Also added
some FBC stuffing to Decoder and Reader. All media plugins need to be recompiled,
in case anyone has some outside the Haiku tree.

was used, two different threads could decide to share the same mutable string.
* Renamed some functions to make clearer what they do, ie. _Detach() is now
called _MakeWritable().
* Cleaned up some questionable semantics, like the const char* parameter in
_DetachWith() - you can now choose to copy the original string or not with
a boolean. This also makes sure that the string is actually copied when it
has to, which wasn't the case before (but that was no problem with the way
that function was used).
* Made the header compliant with our style guide.
* Further cleanup.
* All BString related unit tests are passed, so I guess I didn't break too
much :-)

boot device is actually read-only (even if it's using the write overlay).
* Do not create a swap file on a read-only device - this would really be a
stupid use of the write overlay (just saw this happening on an older
machine).
* Made swap_file_{add|delete}() take a const char* path - there was no reason
this was writable, and this also avoids casting away the const when adding
the default swap file.
* Minor cleanup.

have a simple dedicated heap for the kernel debugger with stacked allocation
pools (deleting a pool frees all memory allocated in it). The heap should
eventually be used for all commands that need temporary storage too large for
the stack instead of each using its own static buffer.

- While walking down the cache chain, we keep all upper caches locked.
- When we have to unlock -- when waiting for a busy page or reading a page in
-- we unlock completely, including the address space, and restart
vm_soft_fault().
- Folded fault_get_page() and fault_find_page() into one.
This simplifies and improves things considerably:
- We no longer need dummy pages.
- We no longer need vm_area::no_cache_change.
- #2710 is fixed, since we no longer hold the address space lock while
waiting.
* vm_soft_fault(): When we have found our page, we first check whether a page
is already mapped at the address. If it is already our page, we just change
its protection. If not, we unmap it first. Fixes race conditions when multiple
threads fault at the same address at the same time.
* fault_get_page(): When copying a read-only page from a lower cache, no longer
mark it active, since at least for the fault area it is shadowed from then on.
* vm_set_area_protection(): Fixed potential overflow for in the
vm_translation_map::protect() call.

gcc could apparently assume that the register assigned to the one in the
clobber list would keep its value (as can be observed when disassembling
add_debugger_command_etc()).
Using a dummy output register works around the problem and also avoids the
unnecessary initialization of the register.
Comments explaining the mystery welcome.

the syscall. Anything beyond st_mtim was therefore not filled in. Fixes
the incorrectly shown creation times in Tracker.
* The BStatable::GetStat() solution was not sufficient yet. We still have to
provide the old GetStat() symbol for BNode and BEntry, since those could be
used by old applications/libraries. We also still have to implement the old
GetStat() slots in the derived classes, but don't need to implement it in
the base class (was purely virtual before and is private now).
* The old BStatable::_OhSoStatable1() slot function was not implemented
correctly. Calling the virtual function at the vtable slot obviously results
in an infinite recursion. The correct implementation would make use of the
Perform() method, but Be didn't provide one for BStatable, so we have to use
the old GetStat() method. Fixed#3960.

replaced by timespec fields. Via macros the structure is still source
compatible with the old one.
* Introduced header <compat/sys/stat.h> that defines the old stat structure
(as stat_beos) and conversion functions
* Introduced versions for [l,f]stat().
* Added symbol versions for BDirectory::GetStatFor() for sake of binary
compatibility.
* BStatable::GetStat(): Renamed the old method, changed its parameter to
stat_beos*, and and made it private. Added a new version (using up a
reserved vtable slot). It remains source and binary compatible.
* BRefFilter::Filter(): Changed the struct stat* parameter to struct stat_beos*
for sake of binary compatibility. This breaks source compatibility, though,
which we can't help, since the class doesn't have reserved vtable slots.
* Fixed several issues with the stat structure change, mostly adjusted uses of
BRefFilter.

* the cursor keys scroll immediately, not only when the (invisible) caret
reaches the views bounds
* HOME/END work more reliably
