upper layers: you use the store_header() function to mark the header you want
to preserve. All subsequent remove_header() calls won't claim the actual
data, but only move the node start around.
* This header can then be restored by restore_header(). However, a call to
prepend_data() will destroy the stored header. Also, if remove_header() cuts
off a whole node, restoring the header won't succeed anymore.
* Discarded the no longer needed net_buffer::network_header field.
* Also discarded the hoplimit field which temporarily breaks the IPv6 build
until Atis reworks it.
* IPv4 now also dumps the IP header in the send path if debug output is enabled.
* icmp_error_reply() might be called so early that the net_buffer's addresses
do not point to the reply address; this is now detected, and the addresses are
taken out of the IP header in that case.
* Improved dumping the net_buffer to also include its address, and flags.

weird behavior when running in kernel.
* checksumfs_io(): Try to lock with timeout when the request is VIP. This
works around a potential quasi-deadlock: Most write support FS hooks
potentially allocate memory (e.g. in block_cache_get*()) while holding a
write lock to a node. When memory is low they have to wait for pages to
become available. The page writer might block on such node which in turn
would prevent modified pages from becoming eligible for recycling. Should
only in rare low memory cases have led to a problem.

* File::_GrowTree(): The inner loop of the level addition part was bogus.
Apparently I never tested with files >= 2 MB before.

now.
* PageWriterRun::Go(): Returns the number of pages that could not be written.
* 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.

Needs more investigation ...

* uncommented fwscanf() in wchar.h to make it available
As a result, the next build of gcc4 should be able to detect full support for wchar_t and in turn activate wchar_t-based template types (like std::wstring).

* Locale preference : send such a message broadcast to all applications when the settings are changed
* Deskbar : receive the message and forward it to the locale roster. This way the time display on the deskbar changes as
soon as you close the locale preflet.

* _AllocateInGroup(): Fixed incorrect checks. The allocation group counts the
free, not the used blocks.
* _AllocateInBitmapBlock(): Fixed allocation loop. It was neither incrementing
the array pointer, nor resetting the bit offset.

is no mechanism yet to actually forward the error to userland).

* Removed unused include, turned off ICMP debug output.

* The locale roster uses them instead of messing with pointers, to avoid ownership problems
* The Locale preflet works on a copy of the default country instead of altering it directly

instead of always returning B_OK.
* deliver_multicast() now takes the protocol restriction of a raw socket into
account.
* raw_receive_data() now correctly returns whether a buffer was delivered (due
to the protocol restriction, this wasn't the case before).
* ipv4_receive_data() leaked all multicast buffers.
* Some minor cleanup.

2007), and Yin Qiu (GSoC 2008). And even though I needed to rewrite pretty
much all of it because of the countless bugs and problems it had, it still
shares the same architectural problems of introducing a domain dependent
error mechanism to the upper layers, and needing the
net_buffer::network_header hack. This I will rework later.
* net_buffer's append_size(), and prepend_size() will now gracefully handle
buffers without a data node.

an arbitrary block.
