needs to be or'ed to the address specification), "uncached" is assumed.
* Set the memory type for the "BIOS" and "DMA" areas to write-back. Not sure, if
that's correct, but that's what was effectively used on my machines before.
* Changed x86_set_mtrrs() and the CPU module hook to also set the default memory
type.
* Rewrote the MTRR computation once more:
- Now we know all used memory ranges, so we are free to extend used ranges
into unused ones in order to simplify them for MTRR setup.
- Leverage the subtractive properties of uncached and write-through ranges to
simplify ranges of any other respectively write-back type.
- Set the default memory type to write-back, so we don't need MTRRs for the
RAM ranges.
- If a new range intersects with an existing one, we no longer just fail.
Instead we use the strictest requirements implied by the ranges. This fixes
#5383.
Overall the new algorithm should be sufficient with far less MTRRs than before
(on my desktop machine 4 are used at maximum, while 8 didn't quite suffice
before). A drawback of the current implementation is that it doesn't deal with
the case of running out of MTRRs at all, which might result in some ranges
having weaker caching/memory ordering properties than requested.

therefore does not unlock anymore while iterating over the transactions.
This gave other threads the opportunity to finish a transaction, causing
bug #5412. Also, the BlockWriter will now always close transactions on its
own, and you need to pass the transaction hash iterator to Add().
* Also, transactions that contain blocks that are currently written back will
be ignored by the block writer, as well as cache_sync_transaction(). This
fixes bug #5415.
* Improved error handling if BlockWriter fails to write back blocks. Most
notably, they are no longer left busy_writing, and the functions calling
it do proper error reporting (besides block_cache_discard() that does not
return any erro code; I've added a TODO note there for now).
* The BlockWriter now starts with a larger array once it has to allocate one.
* One can now limit the number of blocks that go into a BlockWriter. This is
used by the block writer thread, that shouldn't always write back everything
every two seconds.
* Also, the fixed array is larger now (leaving enough space such that the
block writer/notifier does not need to allocate anything).
* And finally, if allocating the array fails, the BlockWriter falls back to the
synchronous write back used previously. IOW it will never write back less
blocks than you ask for.
* Added static BlockWriter::WriteBlock() method replacing write_cached_block().
* Forgot to rename block_cache::busy_count to busy_reading_count.

* Fix the TimeFormat API, there was a double free. Make it work as expected : you send it a number of seconds and it will format it properly in days, hours, minutes, seconds with proper plural.
* Cleanup other parts of the Format API from useless things. They may get reintroduced later if we feel the need to do so.
* AboutSystem now use TimeFormat to display the uptime in properly localized way.

arch_timer_set_hardware_timer(). This was harmless, at least with our
current x86 timers implementation, since they checked for minimum timeouts.
Very small cleanup (now that the file is compiled as C++).

particular it wouldn't set the flag when writing something to a page, but
only move it to the modified queue. Since mapping the page would move it to
another queue, the information that the page was modified would be lost and
it would never be written to disk. Was well reproducible with a Haiku image
build and limited amount of memory.
Fixes the hopefully last remaining cause for #5374.

* full_scan_inactive_pages(): Fixed syntactical glitch (missing "else").
Affected only the active paging mode and was relatively harmless. The worst
case would be that an inactive page would be moved to the cached queue
although its usage_count hadn't dropped to 0 yet, thus freeing it before
pages that deserved it more.
* move_page_to_active_or_inactive_queue():
- Was ignoring the page's modified flag, thus potentially moving a modified
page to the cached queue. That could happen only in rare cases though,
like when the page was still mmap()ped while being written and modified and
unmapped before being done.
- No longer move the page to the inactive queue, even if its usage count is 0.
In idle mode the page daemon doesn't look at inactive pages, so the page's
stats wouldn't be updated anymore.
- Renamed to move_page_to_appropriate_queue().

daemon will keep track of those pages even in idle mode (where it only
processes the active queue).

Unset() the header in Allocate() before calling it. This fixes bug #5410.
