Applications that don't call open() or like functions too often,
and call many FD-related methods across multiple threads at once
(like "git status") now don't wait on the context lock as much.
("git status" performance isn't much improved because threads just
hit the "unused vnodes" lock instead.)
- Convert libroot from a page to a group, so that it can list the

Exposes a new field on mouse events named "device" that specifices what
type of device the event originates from. This is then used in
PadBlocker to ignore events that don't originate from trackpads.
This field should also be exposed to the public API in case any program
in userspace want to use it, as it may be useful for other purposes.

The driver had its own header file with definitions from the USB video
specification. Use the system ones already in place for use in listusb.
Also recognize devices which advertise themselves as "miscellaneous" in
the device descriptor, this is the recommended way in the specification
as the usb_video interface may be only part of a device, with other
interfaces and endpoints used for audio or for HID for example.

Based on X512's original change, but with more modifications:
* Don't use _ in macro parameter names to appease GCC 2.
* Get rid of ioctl_args struct. We don't need it anymore,
and just adding parameters of the same types has the
exact same ABI on x86 and x86_64, so this doesn't break
any existing compiled code.
* Add (void*) cast to third parameter.
* Enable for _KERNEL_MODE also.

This way, modules can decide to do different things based on having
all the ancillary data available. In particular, the UNIX module will
now post only one message header for all the FDs, even if they came
from multiple sets of ancillary data.
This should fix "Message needs unreceived descriptors" from the Chromium
IPC code (which is used by Firefox).
Same as for the scatter/gather pool. This also changes CCBs
to use condition variables instead of semaphores for completion,
which means they're now C++-only. A few C files still include
<SCSI.h>, but none use CCBs directly, so this works out fine.
A quick check with a compile benchmark didn't show a performance regression.

They were ignored and unused; and in fact can't be made to work
properly since the block_cache always operates on exactly block-sized
buffers, and doesn't have contiguous buffers of multiple blocks
to hand out at all.
No functional change intended.
* Minor tweaks to POSIX sys/param.h for style.
* Don't redefine alignment macros in BSD sys/param.h even conditionally.
And add a few more macros from the real BSD sys/param.h, for convenience.
(Most of these are also declared in musl and glibc's sys/param.h)
Previously, there was only platform_init_heap/platform_release_heap,
which allocated a single static heap region for the heap to use,
and any subsequent heap allocations had to go through the standard
platform_allocate_region, which allocates regions visible both
to the bootloader and the kernel.
But as mentioned in previous changes, it isn't always easy to
release regions allocated that way. And besides, some bootloaders
(like EFI) use a completely separate mechanism to allocate
bootloader-local memory, which will never get "leaked" into
the kernel.
So instead, refactor all platforms to instead provide two
new methods: platform_{allocate,free}_heap_region. On EFI
this is easy to implement; on most other platforms we have
logic based more on the old platform_init_heap or allocate_region.
(On the BIOS loader in particular, we can only fully release
the memory if it's the last thing we allocated in the physical
addresses. If the "large allocation" threshhold is lowered
back to 16 KB, then we are unable to do this enough times
that we will run past the end of the 8 MB identity map and
thus fail to boot. But with the larger threshhold, we don't
leak nearly as much, and don't hit the threshhold.)
This should further reduce the amount of bootloader memory
permanently "leaked" into the kernel's used memory, though
on some platforms it may still be nonzero.

page_num_t is typedef'd to phys_addr_t, so it's 64-bits on 32-bit
platforms with PAE. In fact it's been so since the introduction
of phys_addr_t, so this comment was obsolete from the start...
This breaks kernel C++ ABI.
This mostly just changes the definition (not the size) of string types,
but in at least one case (daddr_t) it does change the size (from 32-
to 64-bit.)
_BEOS_R5_COMPATIBLE_ was defined in ArchitectureRules while
__HAIKU_BEOS_COMPATIBLE is defined in HaikuConfig.h (which is
in the include path for sys/types, SupportDefs, and other
base headers.)
We automatically enable _DEFAULT_SOURCE if _GNU_SOURCE is defined.
Rather than having even more optional methods undefined unless
_GNU_SOURCE manually is, just change all remaining guarts to
use _DEFAULT_SOURCE instead.
Fixes#19095.
