* Moving some functions around, removing and adding others for the public API.
I've written a blog post at haiku-os.org to go as documentation for this
introducing the API and the other helpful bits.

in r23974, but seeing that it was added to the runtime_loader default paths as
well I take it this was an oversight.

the contiguous page allocation function and unlocks a bin locker a bit earlier.

* Make the contiguous page allocation capable of aligning the allocation
and make it more clever by checking up front if there's a chance of getting
enough pages at all, by giving up earlier if the page count can't be fit
anymore, and in the alignment case by only checking the pages which have a
valid alignment.
* If the alignment requirement is > B_PAGE_SIZE we now use page allocation
directly, because the bins aren't necesarily aligned on their size past
B_PAGE_SIZE anymore.
* When doing aligned bin allocation, calculate the aligned size up front and
choose the right heap for the allocation.
* Also when doing aligned bin allocations we not only need to round up the size
but also ensure that the bin we choose is aligned at all.
* Moved adding leak check info into it's own function.
Fixes various misalignment problems when working with alignments > B_PAGE_SIZE
or when using alignments < allocation size. Also the directly aligned page
allocations now only use up as many pages as actually required instead of
allocating based on the rounded up to align size.

always behave as if within a transaction. Otherwise all drawing calls to such
BViews wait for the server to finish the request. This change gives a tremendous
speed boost for these situations and is compatibly with BeOS, since there you
also had to call Sync() before drawing a bitmap that was painted with attached
views.

* Reset the DropIndex when the drag is exiting the window.
* Otherwise, the anticipation rect isn't set back on when you enter again the window.
Fixes ticket #3199.

consider that when filling in the text and data ranges of the image info.
This fixes#5361 and #5351, caused by libtracker.so not finding its own
image.

* Don't assume that ids to be contiguous (and to start at 0).
* Use the executable's name as the replicant view name (to ease its identification and removal)
Fixes ticket #5354.

--update option wouldn't correctly pick it up.

doesn't know them. Not sure why that was commented out -- only this way the
build system knows that the libs aren't available. Fixes the non-Haiku build.

* Simplified the Jamfile building these libraries.

going on. I only wanted to have it in the repository in case we decide at a
later point that it is a good idea after all.

its own source file now that the page daemon source file is gone.

* Added vm_clear_page_mapping_accessed_flags() and
vm_remove_all_page_mappings_if_unaccessed(), which combine the functionality
of vm_test_map_activation(), vm_clear_map_flags(), and
vm_remove_all_page_mappings(), thus saving lots of calls to translation map
methods. The backend is the new method
VMTranslationMap::ClearAccessedAndModified().
* Started to make use of the cached page queue and changed the meaning of the
other non-free queues slightly:
- Active queue: Contains mapped pages that have been used recently.
- Inactive queue: Contains mapped pages that have not been used recently. Also
contains unmapped temporary pages.
- Modified queue: Contains unmapped modified pages.
- Cached queue: Contains unmapped unmodified pages (LRU sorted).
Unless we're actually low on memory and actively do paging, modified and
cached queues only contain non-temporary pages. Cached pages are considered
quasi free. They still belong to a cache, but since they are unmodified and
unmapped, they can be freed immediately. And this is what
vm_page_[try_]reserve_pages() do now when there are no more actually free
pages at hand. Essentially this means that pages storing cached file data,
unless mmap()ped, no longer are considered used and don't contribute to page
pressure. Paging will not happen as long there are enough free + cached pages
available.
* Reimplemented the page daemon. It no longer scans all pages, but instead works
the page queues. As long as the free pages situation is harmless, it only
iterates through the active queue and deactivates pages that have not been
used recently. When paging occurs it additionally scans the inactive queue and
frees pages that have not been used recently.
* Changed the page reservation/allocation interface:
vm_page_[try_]reserve_pages(), vm_page_unreserve_pages(), and
vm_page_allocate_page() now take a vm_page_reservation structure pointer.
The reservation functions initialize the structure -- currently consisting
only of a count member for the number of still reserved pages.
vm_page_allocate_page() decrements the count and vm_page_unreserve_pages()
unreserves the remaining pages (if any). Advantages are that reservation/
unreservation mismatches cannot occur anymore, that vm_page_allocate_page()
can verify that the caller has indeed a reserved page left, and that there's
no unnecessary pressure on the free page pool anymore. The only disadvantage
is that the vm_page_reservation object needs to be passed around a bit.
* Reworked the page reservation implementation:
- Got rid of sSystemReservedPages and sPageDeficit. Instead
sUnreservedFreePages now actually contains the number of free pages that
have not yet been reserved (it cannot become negative anymore) and the new
sUnsatisfiedPageReservations contains the number of pages that are still
needed for reservation.
- Threads waiting for reservations do now add themselves to a waiter queue,
which is ordered by descending priority (VM priority and thread priority).
High priority waiters are served first when pages become available.
Fixes#5328.
* cache_prefetch_vnode(): Would reserve one less page than allocated later, if
the size wasn't page aligned.

that does not have a transaction.
* This should fix#5340.

pose list and replaced the rather ugly "fFiltering ? ..." everywhere with it.
* Automatic whitespace cleanup.

* Automatic whitespace cleanup.
* Minor other cleanup.

* Remove no longer necessary support functions.
* The new version uses a single BString as input/output parameter and only
modifies that one by removing non-fitting chars and inserting the ellipsis
where appropriate, so avoids copying around bytes/chars/strings in a few
places. It uses the new Chars functions of BString so also no need for manual
multibyte handling.
* Adjusted the BFont and ServerFont usage of truncate_string() which are both
simplified by using the single BString. It avoids a lot of temprary
allocations and string copying. The char * version of BFont
GetTruncatedStrings() now uses the BString version and not the other way
around anymore which requires us to allocate temporary BString objects, it's
not worse than before though.
* This fixes a bunch of problems with the previous functions like always
prepending the ellipsis for B_TRUNCATE_BEGINNING, crashing on short enough
widths, violating the width in the B_TRUNCATE_END case when the width was
short enough, non-optimal truncation in a few cases and sometimes truncation
where none would've been needed. Also fixes#4128 which was a symptom of the
broken B_TRUNCATE_BEGINNING.

compatibility between two different versions of a shared library.
Even when using this tool, you still need to make up your mind about compatibility, but
IMHO it helps a lot.

Worse yet for a small enough length it actually crashes.
