The SR register in the `CPUM68KState` struct does not contain the value
of the lower 5 flags. To compute them, we must OR the CCR values with
the SR register to get the true SR value.

ci(rust): rework workflow
The notable changes are migrating to
`actions-rust-lang/setup-rust-toolchain` for setting up Rust as it's
maintained, and using `katyo/publish-crates` for publishing crates in a
workspace

fix(rust): correct unsound pointer cast
The size of `T` is not guaranteed to be the size of `i32` - all we know
is that `T` is `Into<i32>`, so we should first copy them over into an
`i32` array

fix(mips): lowercase enum name `uc_mips_reg`
This aligns with other architectures
Co-authored-by: Amaan Qureshi <amaanq12@gmail.com>
uc_query expects a size_t *, while we are passing uc_arch *. This has
been working for a while as gcc just warned about this, however with
latest gcc this changed into an error:
unicorn.c:122:34: error: passing argument 3 of ‘uc_query’ from incompatible pointer type [-Wincompatible-pointer-types]
206 | uc_query(_uc, UC_QUERY_ARCH, &arch);
unicorn.h:689:60: note: expected ‘size_t *’ {aka ‘long unsigned int *’} but argument is of type ‘uc_arch *’
689 | uc_err uc_query(uc_engine *uc, uc_query_type type, size_t *result);
Fix this issue by querying the result into a size_t and later downcast
the result into an uc_arch enum.
- Use full code length (instead of subtracting 1) when writing instructions.
- Uniformly zero-pad addresses in logs and print hexadecimal.
- Correct the instruction-hook callback in test_riscv2.
* arm64 python: Avoid nested class in insn hook for 10x hook speedup
Promote CpReg to a module-level class to address unnecessary performance
reduction. In a real-world use case tracing the emulation of real-world
machine code, this change reduces time spent in CpReg namedtuple
construction from 10% of overall time to below 1%, for a 10x speedup of
the insn hook itself, or a 10% overall speedup. Measured using
cProfile, python 3.13.
* upgrade distro to 22.04
* revert to 22.04 for now
* also revert for wheels

Unlike some other architectures, RISC-V does not expose the current
privilege mode in any architecturally-defined register. That is intentional
to make it easier to implement virtualization in software, but a Unicorn
caller operates outside of the emulated hart and so it can and should be
able to observe and change the current privilege mode in order to properly
emulate certain behaviors of a real CPU.
The current privilege level is therefore now exposed as a new
pseudo-register using the name "priv", which matches the name of the
virtual register used by RISC-V's debug extension to allow the debugger
to read and change the privilege mode while the hart is halted. Unicorn's
use of it is conceptually similar to a debugger.
The bit encoding of this register is the same as specified in RISC-V Debug
Specification v1.0-rc3 Section 4.10.1. It's defined as a "virtual"
register exposing a subset of fields from the dcsr register, although here
it's implemented directly inside the Unicorn code because QEMU doesn't
currently have explicit support for the CSRs from the debug specification.
If it supports "dcsr" in a future release then this implementation could
change to wrap reading and writing that CSR and then projecting the "prv"
and "v" bitfields into the correct locations for the virtual register.
