Restructure this script so that it generates a header of tables instead
of a source file. The tables are included in a flags.c source file which
provides functions to decode various system call arguments.
For functions that decode an enumeration, the function returns a pointer
to a string for known values and NULL for unknown values.
For functions that do more complex decoding (typically of a bitmask), the
function accepts a pointer to a FILE object (open_memstream() can be used
as a string builder) to which decoded values are written. If the
function operates on a bitmask, the function returns true if any bits
were decoded or false if the entire value was valid. Additionally, the
third argument accepts a pointer to a value to which any undecoded bits
are stored. This pointer can be NULL if the caller doesn't care about
remaining bits.
Convert kdump over to using decoder functions from libsysdecode instead of
mksubr. truss also uses decoders from libsysdecode instead of private
lookup tables, though lookup tables for objects not decoded by kdump remain
in truss for now. Eventually most of these tables should move into
libsysdecode as the automated table generation approach from mksubr is
less stale than the static tables in truss.
Some changes have been made to truss and kdump output:
- The flags passed to open() are now properly decoded in that one of
O_RDONLY, O_RDWR, O_WRONLY, or O_EXEC is always included in a decoded
mask.
- Optional arguments to open(), openat(), and fcntl() are only printed
in kdump if they exist (e.g. the mode is only printed for open() if
O_CREAT is set in the flags).
- Print argument to F_GETLK/SETLK/SETLKW in kdump as a pointer, not int.
- Include all procctl() commands.
- Correctly decode pipe2() flags in truss by not assuming full
open()-like flags with O_RDONLY, etc.
- Decode file flags passed to *chflags() as file flags (UF_* and SF_*)
rather than as a file mode.
- Fix decoding of quotactl() commands by splitting out the two command
components instead of assuming the raw command value matches the
primary command component.
In addition, truss and kdump now build without triggering any warnings.
All of the sysdecode manpages now include the required headers in the
synopsis.

All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.
Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw
Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.

Previously pass driver just ignored the flag, making random kernel code
access user-space pointer, sometime causing crashes even for correctly
written applications if user-level context was switched or swapped out.
This patch tries to copyin the CDB into kernel space to avoid it.

In r10905 and r10906 makesyscalls was modified to avoid emitting a
literal $Id$ string in the generated file, with:
gsub("[$]Id: ", "", $0)
gsub(" [$]", "", $0)
Then r11294 added some functionality and also tried to address the $Id$
problem in a different way, by removing every $:
sed -e 's/\$//g ...
This rendered the gsub infeffective. The gsub was later updated to
track the $Id$ -> $FreeBSD$ switch, even though it did not do anything.
Revert the addition of the s/\$//g, and update the gsub to keep the
resulting format the same.

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().
Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.
While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

If device reservation was preempted by other initiator, our sync request
will always fail. Without this change CAM tried to sync cache on every
following device close, including numerous GEOM tasting opens/closes,
causing lots of useless noise in logs.
While there, increase SYNCHRONIZE CACHE timeout to default value.

This commit, long overdue, contains contributions in the last 2 years
from Stefano Garzarella, Giuseppe Lettieri, Vincenzo Maffione, including:
+ fixes on monitor ports
+ the 'ptnet' virtual device driver, and ptnetmap backend, for
high speed virtual passthrough on VMs (bhyve fixes in an upcoming commit)
+ improved emulated netmap mode
+ more robust error handling
+ removal of stale code
+ various fixes to code and documentation (some mixup between RX and TX
parameters, and private and public variables)
We also include an additional tool, nmreplay, which is functionally
equivalent to tcpreplay but operating on netmap ports.
These allocations can reach up to 128KB, while FreeBSD kernel allocator
can cache allocations only up to 64KB. To avoid expensive allocations
for each large ZIL write use caching zio_buf_alloc() allocator instead.
To make it possible de-inline few instances of zil_itx_destroy().
Split efirt.ko initialization into early stage where runtime services
KPI environment is created, to be used e.g. for RTC, and the later
devfs node creation stage, per module.
Switch the efi device to use make_dev_s(9) instead of make_dev(9). At
least, this gracefully handles the duplicated device name issue.
Remove ARGSUSED comment from efidev_ioctl(), all unused arguments are
annotated with __unused attribute.

r306065/r306067 introduced ofw_parse_bootargs(), setting environment variables
from Open Firmware's /chosen/bootargs property. On systems booting with
loader(8) (meaning, most systems), the initial static kenv is created with no
extra space, causing kern_setenv() to panic. Since these already have the
environment set directly, there is no need to parse bootargs anyway.
