3283fc3f61 cpu: add support for detecting RISC-V extensions 
Add a RISCV64 variable to cpu that indicates both the presence
of RISC-V extensions and performance information about the underlying
RISC-V cores.  The variable is only populated with non false values on
Linux.  The detection code first attempts to use the riscv_hwprobe
syscall introduced in Linux 6.4, falling back to HWCAP if riscv_hwprobe
is not supported.  The patch can detect the C, V, Zba, Zbb and Zbs
extensions.  V, Zba, Zbb and Zbs can only be detected on a 6.5 kernel
or later (without backports).

Updates golang/go#61416

a8c5219b5e unix: rename XDPUmemReg field back to Size 
When the Linux-specific XDPUmemReg struct was originally added
(CL 136695) the only field with a prefix was chunk_size,
so cgo rewrote the field to Size. Later Linux added a tx_metadata_len
field, which caused cgo to to leave the chunk_size field as Chunk_size
(CL 577975).

However, existing code, specifically gvisor, refers to the field
as Size. So go back to Size so that existing code will continue
to work.

This does unfortunately mean that people who used the struct since CL
577975 in April, 2024 will have to adapt. There doesn't seem to be a
perfect solution here. But we've had Size since September, 2018,
so let's stick with that.

914deed708 unix: add missing ETHTOOL_FLAG_ constants 
Some constants were removed in CL 600516 that included changes for the
Linux kernel 6.10.

This kernel version moved C defines to an enum ethtool_header_flags that
was not picked up by the mkall.sh script.

For enums, there is a perl script that needs to be run manually, and the
output must be added by hand to the list of constants in unix/linux/types.go.

See https://elixir.bootlin.com/linux/v6.10.3/source/include/uapi/linux/ethtool_netlink.h#L120

348425aa18 windows/svc: do not pass theService to windows.RegisterServiceCtrlHandlerEx 
windows.RegisterServiceCtrlHandlerEx context parameter is uintptr, so it
is unsafe to pass pointers in that parameter. Use theService global
variable in ctlHandler function instead.

f34bb9fccc windows: add net user enum 
In the go windows package, you can get user information by using
`NetUserGetInfo` along with a specified level. However, there is
no way to get a list of the users.
The only options are to
1. know the users,
2. brute force users, or
3. use an external tool or command (`net users`).

I suggest adding a function that implements the windows api for
`NetUserEnum`. This will allow a built in way to enumerate
users and follow the standard.

A side note is that I used `buf **byte` because
it is how the others are done, but using `buf *byte`
works just as well.

7d69d983c4 unix: extend support for z/OS 
This change syncs the IBM internal version of sys/unix with the public
repository.

There are a variety of new syscalls and const definitions that have been
accumulated over the past few years to support developers using Go on
the platform. Old simulations of calls like 'epoll' and 'fstatfs' have
been replaced with their real counterparts. The zos/s390x syscalls also
have extensive trampolining to handle zos systems that might not have
support for some of these new system calls.

Closes golang/go#67071

cabba82f75 windows: use uint32 for serial comm flags for consistency 
This is a follow-up to https://go-review.googlesource.com/c/sys/+/572295
and specifically the comment
https://go-review.googlesource.com/c/sys/+/572295/comment/a00e1a2e_e3b01666/.

All other structs and methods us uint32 in golang.org/x/sys/windows
for flag bitmasks, so make the serial communication structs use uint32
to be consistent with the rest of the package.

As a side effect the DTR_CONTROL_* and RTS_CONTROL_* constants are
updated to reflect the positions of the bits in the 32-bit flags.

x/sys/unix already has equivalent functionality through termios.
