ddb: print the actual syscall name
Some architectures will pretty-print a system call trap in the
backtrace. Rather than printing the symbol, use the syscallname()
function to pull the string from the sv_syscallnames array corresponding
to the process. This simplifies the function somewhat.
Mostly, this will result in dropping the "sys" prefix, e.g. "sys_exit"
will now be printed simply as "exit".
Make two minor tweaks to the function signature: use a u_int for the
syscall number since this is a more correct type (see the 'code' member
of struct syscall_args), and make the thread pointer the first argument.
The latter is more natural and conventional.

release: Add support for creating ZFS-based VM images
The change extends vmimage.subr to handle a new parameter, VMFS, which
should be equal to either "ufs" or "zfs". When it is set to ZFS, we use
makefs to create a bootable pool populated using the same dataset layout
as bsdinstall and "poudriere image" use. The pool can be grown using
the growfs rc.d script, just as in UFS images.
This will make it easy to provide VM and cloud images with ZFS as the
root filesystem. So far I did not do extensive testing of cloud images;
I merely verified that creation of ZFS-based AWS AMIs works and allows
me to create amd64 and arm64 EC2 instances with ZFS as the root
filesystem.

riscv: improve parsing of riscv,isa property strings
This code was originally written under the assumption that the ISA
string would only contain single-letter extensions. The RISC-V
specification has extended its description of the format quite a bit,
allowing for much longer ISA strings containing multi-letter extension
names.
Newer versions of QEMU (7.1.0) will append to the riscv,isa property
indicating the presence of multi-letter standard extensions such as
Zfencei. This triggers a KASSERT about the expected length of the
string, preventing boot.
Increase the size of the isa array significantly, and teach the code
to parse (skip over) multi-letter extensions, and optional extension
version numbers. We currently ignore them completely, but this will
change in the future as we start supporting supervisor-level extensions.
