The riscv_hwprobe system call was introduced in Linux 6.4 and allows
the caller to determine a number of interesting pieces of information
about the underlying RISC-V CPUs, e.g., which extensions they support
and whether they allow fast unaligned memory accesses. For more information
please see:
https://docs.kernel.org/riscv/hwprobe.html
We also update linux/mksysnum.go to ensure that the generated syscall constants
written to the zsysnum_linux_*.go files are always sorted by their syscall numbers
in ascending order.

As of Go 1.21 syscall.Setrlimit and syscall.prlimit can affect
starting a new process, by restoring the original NOFILE rlimit.
That is recorded locally in the syscall package, so just always
call the syscall functions.

For linux and *bsd, implement func fcntl in fcntl.go instead of
generating it. Implement it using fcntl64Syscall, so SYS_FCNTL64 is used
on 32-bit linux.
For aix, darwin and solaris continue generate func fcntl as before.

Asymmetric keyrings can require key payloads to be X.509 certificates
signed by a key in a different keyring. This can be helpful for rotating
keys on a live machines for subsystems like IMA while preventing local
tampering.
Tested locally by applying the "key_or_keyring:<id>" restriction to a
keyring.

The kernel raw syscall takes an additional parameter specifying
the size of the Sigset_t parameter, returns a file descriptor and sets errno.
Add a uintptr maxSize parameter, adjust the return to be (newfd int, err error).
Add the _NSIG #define and a wrapper to call with maxSize set to _C__NSIG/8 as done
in glibc/musl.

Add syscall wrappers, error constants and types for linux/riscv64
Switch docker image to Ubuntu 18.10 in order to get qemu supporting
riscv64. Also set the uname release string for qemu to 4.15 (the first
Linux kernel version with riscv64 support), because otherwise running
the generating C program in mkerrors.sh on a host with an older kernel
would fail with a "FATAL: kernel too old".
Note that linux/riscv64 is currently only usable using gccgo.
