rust: silence unknown warnings for the sake of old compilers

Occasionally, we may need to silence warnings and clippy lints that
were only introduced in newer Rust compiler versions. However, this
would fail when compiling with an older rustc:

error: unknown lint: `non_local_definitions`
--> rust/qemu-api/rust-qemu-api-tests.p/structured/offset_of.rs:79:17

So by default we need to block the unknown_lints warning. To avoid
misspelled lints or other similar issues, re-enable it in the CI job
that uses nightly rust.

linux-user: Allow custom rt signal mappings

Some applications want to use low priority realtime signals (e.g.,
SIGRTMAX). Currently QEMU cannot map all target realtime signals to
host realtime signals, and chooses to sacrifice the end of the target
realtime signal range.

Allow users to choose how to map target realtime signals to host
realtime signals using the new -t option, the new QEMU_RTSIG_MAP
environment variable, and the new -Drtsig_map=\"...\" meson flag.
To simplify things, the meson flag is not per-target, because the
intended use case is app-specific qemu-user builds.

The mapping is specified using the "tsig hsig count[,...]" syntax.
Target realtime signals [tsig,tsig+count) are mapped to host realtime
signals [hsig,hsig+count). Care is taken to avoid double and
out-of-range mappings.

device/virtio-nsm: Support for Nitro Secure Module device

Nitro Secure Module (NSM)[1] device is used in AWS Nitro Enclaves[2]
for stripped down TPM functionality like cryptographic attestation.
The requests to and responses from NSM device are CBOR[3] encoded.

This commit adds support for NSM device in QEMU. Although related to
AWS Nitro Enclaves, the virito-nsm device is independent and can be
used in other machine types as well. The libcbor[4] library has been
used for the CBOR encoding and decoding functionalities.

configure, meson: synchronize defaults for configure and Meson Rust options

If the defaults for --enable-rust ($rust in configure) and Meson's rust
option are out of sync, incremental builds will pick Meson's default.

This happens because, on an incremental build, configure does not run
Meson, Make does instead. Meson then gets the command line options
from either coredata.dat (which has everything cached in Python's pickle
format) or cmd_line.txt (slow path when Meson version is upgraded), but
neither knows about the rust option, and the meson_options.txt default
is used.

This will cause have_rust to be true if rustc is available; and the build
to fail because configure did not put a RUST_TARGET_TRIPLE in config-host.mak.

When in the Rust pull request I changed the $rust default from auto
to disabled, I should have made the same change to meson_options.txt;
do it now.

meson: Split --enable-sanitizers to --enable-{asan, ubsan}

We do not always want both address and undefined behavior
sanitizers running at the same time.

For the gitlab custom-runners, drop to only --enable-ubsan.
These jobs are not run by default, but as will be obvious in the
next patch, we don't run ASan on x86 either, and it seems wrong
to hold aarch64 and s390x to a different standard.
