This new driver uses the "generic" TTY layer, unlike the old driver
which had its own implementation (which the generic module was derived
from, originally.)
The remaining bits of support for controlling TTYs is added to the kernel &
generic layer at the same time, which should allow for serial interfaces
to be controlling terminals now, as well.
Tested with bash, nano, vim; all seems to still be working as expected.
Exported `pthread_attr_get_np` under `_DEFAULT_SOURCE`. Otherwise,
the presence of this function in `libroot.so` without a definition
would confuse some configuration scripts.

See #18351 for details on the specifications.
This is the same thing NetBSD does. BeOS R5 defined these values
differently than we did even before this commit, and it does not
seem to have caused problems then, so this should be fine.
While technically an ABI break, in practice these values are not
always differentiated on other platforms, and it appears musl's
code triggers divide-by-zero exceptions on purpose before it
returns this value, anyway.
Fixes#18351.
* Make some code common in Insert.
* Remove unneeded logic from InsertAfter and just call the base Insert.
InsertBefore does this, already.
* Synchronize Insert code and APIs in the fs_shell DoublyLinkedList.
Removing it outright would cause implicit conversions and then the other
variant being called, which would create invalid lists. So make it private
so that any attempts to use it will create errors at compile-time.
As far as I can tell, it has no consumers whatsoever outside the tree.
(wpa_supplicant did not even use it.) So, remove it altogether.
If that turns out to be mistaken, we can reinstate it temporarily
as a private class function or ABI-only symbol.
Since we used a hash table with a fixed size (1024), collisions were
obviously inevitable, meaning that while insertions would always be
fast, lookups and deletions would take linear time to search the
linked-list for the area in question. For recently-created areas,
this would be fast; for less-recently-created areas, it would get
slower and slower and slower.
A particularly pathological case was the "mmap/24-1" test from the
Open POSIX Testsuite, which creates millions of areas until it hits
ENOMEM; it then simply exits, at which point it would run for minutes
and minutes in the kernel team deletion routines; how long I don't know,
as I rebooted before it finished.
This change fixes that problem, among others, at the cost of increased
area creation time, by using an AVL tree instead of a hash. For comparison,
mmap'ing 2 million areas with the "24-1" test before this change took
around 0m2.706s of real time, while afterwards it takes about 0m3.118s,
or around a 15% increase (1.152x).
On the other hand, the total test runtime for 2 million areas went from
around 2m11.050s to 0m4.035s, or around a 97% decrease (0.031x); in other
words, with this new code, it is *32 times faster.*
Area insertion will no longer be O(1), however, so the time increase
may go up with the number of areas present on the system; but if it's
only around 3 seconds to create 2 million areas, or about 1.56 us per area,
vs. 1.35 us before, I don't think that's worth worrying about.
My nonscientific "compile HaikuDepot with 2 cores in VM" benchmark
seems to be within the realm of "noise", anyway, with most results
both before and after this change coming in around 47s real time.

The kernel heap only uses object caches for objects up to size 8192.
Larger allocations have to go through the raw allocator. That can
get pretty expensive.
Adding instrumentation around the malloc/free calls in this function
showed that on my machine, some 596ms during boot were spent on
*malloc/free alone*, all else aside. After this change, we are at
around 110ms, or a >5x improvement. Running an fgrep -R on /system/
after boot increased the cumulative time in memory functions to over
5 seconds, while after this change it is "only" 1170ms.
Honestly, it seems like the object depots should be able to be faster
than that, even if this function is called thousands of times. But that
is a problem for a different investigation.
It would be even faster for every consumer of this data in
packagefs just allocated one set of buffers up front, or at least
for a single "read session", but plumbing that all the way
through the myriad abstractions of the Package Kit will
not be easy, and is left for another time, as well.
While the BSDs and glibc seem to have various _r functions,
they all return int for errors instead of a pointer, making ours
exactly backwards of theirs for error reporting and thus useless.
So, remove them from the header entirely. They are left in
for ABI backwards compatibility for the time being.
A few constants not used by anything in the tree (i.e. not actually
implemented by libnetwork/netresolv) were also dropped. Some deprecated
or non-standard functions were placed behind _DEFAULT_SOURCE or deleted
entirely.
The header itself is now organized approximately as the BSDs do,
although with various Haiku-isms instead of BSD-isms where appropriate.
In fixed size mode, the menu field always uses all the available width.
In non-fixed size mode, the menu field will resize itself to be as small
as possible.
With layout, usually the difference isn't noticeable, since the layout
will already try to resize the control to the smallest possible size.
But there are a few cases where it makes a difference, when the layout
is over-constrained and the menu field can't be made as small as
possible. In that case, the menu field would be forced to fill its
allocated space, where we can instead make it a little smaller.

They are not about reading and writing pages, but just iovecs.
As the passed iovecs use void*s, it can't possibly be working with

"Newer" synaptics touchpad support a new mode where they can report more
information to the host. In this mode, there is a different packet
format for tracking extra data from the touchpad, including a wheel
encoder (mousewheel) if available, and multitouch finger tracking.
This mode is documented in the Synaptics touchpad interfacing guide
(Synaptics document 511-000275-01 Rev. B), but was not yet implemented
in our driver.
It should help with detecting multiple fingers, or finger position on
clickpads to determine right or left click.
This change implements the following items from the Synaptics
interfacing guide:
- Cleanup and clarify the code for features detection to properly report
clickpads
- Enable "extended W" mode if supported
- Process extended W values 0 (mouse wheels, reported in the
touchpad_event structure and could be used by input_server for
scrolling), 1 (secondary finger), and 2 (finger count)
- Fix handling of wValue, which is not always a finger width
- Add handling of vValuen which indicates the finger width when wValue
doesn't
Overall, this should provide the movement_maker with a better picture of
what's happening.
Also improve tracing to show received packets and the corresponding
WValue since that's an important value in identifying which type of
packet it is.
Unfortunately I currently don't have a laptop with synaptics touchpad to
test this with.

This is duplicated across multiple filesystems, and could probably be

Adjusted only BFS, EXT2, and NTFS in this commit, as they are the ones
which make use of fs_ops_support.h already and thus need to be modified
to avoid duplicate-definition errors.
Also tweak next_dirent to support being built under fs_shell.
(Possibly we should define ASSERT there, though?)
