6938dae65e unix: add missing constants used with struct Timex on Linux 
This provides definitions for Linux of two groups of constants,
which are used with struct Timex (used with the adjtimex and
clock_adjtime system calls): the ADJ_* constants are used
for the modes field; the STA_* constants are used for the status
field. The constants are documented in the adjtimex(2) man page.

Fixes golang/go#58012

af78867b19 unix/linux: update to Linux kernel 5.19-rc2 
Update to 5.19-rc2 instead of 5.18 for the following reasons:

- Support for LoongArch has been merged upstream. This allows to drop
  the loong64 specific kernel patches.
- Fixes [1] an issue encountered with when generating the
  SOCK_TXREHASH_DEFAULT constant from linux/socket.h on 5.18
- Contains a fix [2] to provide SYS_MEMFD_SECRET on linux/riscv64 as
  well, The underlying syscall was already available in earlier kernel
  versions. Also see golang/go#51547.

a851e7ddee unix: change Landlock type aliases to new types 
Type aliases were introduced in CL 348349 and I did not notice it during
the review process. The typical convention is to create new types instead.

bce67f0961 unix: add SetsockoptTCPRepairOpt on Linux 
There is currently no function to allow for setting repair options for sockets in repair mode.
There are 4 options catered for in the linux implementation.

TCPOPT_WINDOW
TCPOPT_MAXSEG
TCPOPT_SACK_PERMITTED
TCPOPT_TIMESTAMP

Details of the patch to the kernel and the thinking behind it is here  https://lwn.net/Articles/495304

Work done in this commit
Included the tcp options type and length for inclusion in the Docker build
Added TCPOPT to the regular expression in mkerrors.sh. There was only TCP_ previously
Add the new function to syscall_unix.go

I have tested locally and verified each option with ss -i

I am not sure whether to commit tests because I don't know if socket creation is possible on the test runs in the offical pipeline.
I did check for existing tests but didn't see any that created sockets, only one that validated a string option.

Fixes golang/go#46984

b80eb88b80 unix: add HIDRAW ioctls 
This change adds (most) of the ioctl API for the Linux HIDRAW interface.
Reading and writing non-numbered HID reports is done using the read and
write system calls respectively.

Some of the HIDIOC* request numbers are exported directly while others
are kept unexported. This is because some of the #defines require a len
attribute that doesn't have a specific well defined value.

Wrapper types are added for most of the request numbers as is standard.
No wrapper is added for HIDIOCGRDESCSIZE as it would just be
IoctlGetUint32.

The HIDIOC[GS]FEATURE, HIDIOC[GS]INPUT and HIDIOC[GS]OUTPUT request
numbers, which are required for numbered HID reports, are entirely
ommitted as the len attribute has to be a runtime variable. These could
be added later by doing something like
 `HIDIOCGFEATURE(0) | (len << _IOC_SIZESHIFT)`,
with care taken that len doesn't overflow _IOC_XSIZEMASK.

Outdated documentation for the HIDRAW interface is available at:
https://www.kernel.org/doc/Documentation/hid/hidraw.txt.
