turned out it's pretty much broken. Not only did it potentially leak memory,
it would also potentially replace the original data with a NULL pointer,
making the current transaction non revertable. The code should now be much
clearer. This fixes bug #6378.
* Changed a few "if (... != NULL)" into ASSERTs, since the code should bail out
earlier in these cases already.
* Added a TODO comment to cache_start_sub_transaction() about its broken discard
handling. This can cause FS corruptions in case the parent transaction is ever
going to be aborted (which shouldn't happen in real life, though).
* Added a bit more and better comments.

never really being used for what it meant (and just being referred to by
gettimeofday(), which put a different meaning to it
* adjusted the syscalls get_timezone() & set_timezone() as well as their callers
accordingly
* got rid of get_rtc_info() and rtc_info struct in kernel, as it was only
being referred to by the FAT add-on and that one (like gettimeofday()) put a
different meaning to tz_minuteswest. Added a comment to FAT's util.c
showing a possible solution, should the hardcoded GMT timezone pose a problem.
* fixed declaration of gettimeofday() to match POSIX base specs, issue 7
* changed implementation of gettimeofday() to not bother trying to fill struct
timezone - it was using wrong values before, anyway.

interface - this caused quite a number of changes.
* Network interfaces, and its addresses are now reference counted (not yet
complete, though, InterfaceAddresses need to hold references to their
interface as well).
* There are two known regressions of this commit that I will fix later:
- you cannot remove interfaces anymore
- IPv4 multicast was broken anyway, but now it's disabled, too.
* Moved a device_interfaces.cpp|h out of interfaces.cpp.
* The datalink layer chain is now instantiated per domain per interface,
not just per interface anymore.
* When a buffer reaches the network layer, it has no known interface yet, ie.
the ipv4|6|whatever modules need to set this manually.
* Added more debug output, and some new debugger commands, the control option
is now printed in clear text.
* Added hash_address() function to the address modules. Added "const" to
set_to_defaults() where needed.
* Fixed net_buffer's restore header functions offset use as reported by Atis.
* Improved buffer dump output, use the domain module to print the address if
available.
* Moved net_buffer::type into the union, as it's not needed by the upper layers
anymore.
* Moved IPv6 specific code from {add|remove}_default_route() to where it
belongs, but disabled it for the time being.
* Completely discarded useless ipv4_datagram module.
* Added ping6 to the build.

* page_writer()/next_modified_page():
- Don't use a marker page anymore. A visited page is requeued at the tail.
This also makes the functions that schedule pages work a bit better (they
queue the pages at the head of the queue).
- Have an eye on pages that are busy or failed to write. If we ran through
the whole modified queue without writing a single page, sleep for a short
time. This mitigates the busyness the page writer falls into when there
are enough modified pages to make it run all the time but none that can be
written successfully.

potentially misalign the object again.

alignment parameter anyway (the flag is still used for the MemoryManager,
though).
* ObjectCache::InitSlab(): Slab coloring *was* done when CACHE_ALIGN_ON_SIZE

* Made vm_page::wired_count private and added accessor methods.
* Added VMCache::fWiredPagesCount (the number of wired pages the cache
contains) and accessor methods.
* Made more use of vm_page::IsMapped().
* vm_copy_on_write_area(): Added vm_page_reservation* parameter that can be
used to request a special handling for wired pages. If given the wired pages
are replaced by copies and the original pages are moved to the upper cache.
* vm_copy_area():
- We don't need to do any wired ranges handling, if the source area is a
B_SHARED_AREA, since we don't touch the area's mappings in this case.
- We no longer wait for wired ranges of the concerned areas to disappear.
Instead we use the new vm_copy_on_write_area() feature and just let it
copy the wired pages. This fixes#6288, an issue introduced with the use
of user mutexes in libroot: When executing multiple concurrent fork()s all
but the first one would wait on the fork mutex, which (being a user mutex)
would wire a page that the vm_copy_area() of the first fork() would wait
for.
