Rust 1.49.0 needed the 0001-rustc_target-Fix-dash-vs-underscore-mismatches-in-op.patch
patch and newer versions not.

The rust patches for riscv64 have been upstreamed
and are not needed anymore.
The riscv64 patches for libstd-rs need to be
applied to libc-0.2.93 to work. Some slight
modifications are necessary.

* Convert to new override syntax
This is the result of automated script (0.9.0) conversion:
oe-core/scripts/contrib/convert-overrides.py .
converting the metadata to use ":" as the override character instead of "_".
Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>
* Manually fix the conversion

* layer.conf: Update layer compatibility with only dunfell and newer.
Add honister to mark the layers as compatible with honister now that it uses
the new override syntax.
Drop zeus and older which are missing a support for newer override syntax which
was backported only to 1.46 branch (used by dunfell) and newer, e.g.:

* CI: use YOCTO_BRANCH instead of yocto-${YOCTO_VERSION} for poky checkout
* using latest revision in branch is often better than sticking to
some point releases
Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>
* CI: switch to hardknott branch
* gatesgarth is already EOL, better to use something supported
Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>
* nativesdk: Add some tools in a separate recipe
This brings ATM:
- clippy
- rustfmt
Another approach might be to include these into the existing rust recipe,
but as we can't really use PACKAGECONFIG here it might just overload it.
This way, the tools will be built in parallel and still can be excluded
from the packgae group, if desired.

This mimics what rustup packages into the toolchain contents. The
presence of the sources for the exact std lib can be useful for the
development and IDE integration.

This addition closes#236 requesting the SDK support. The implementation
consists on a yet minimum set of worky functionality;
- Includes rustc, rustdoc and cargo.
- Includes libstd and accompanying lib archives for host and for target.
- Integrates with the standard environment setup script.
- Integrates configurations automatically build for target.
The supported build host is still AMD64 only.
Note that there's no need on introducing crosssdk package as the
official snapshot package serves same way as a non SDK build.
Possible future directions:
- Offline build:
- Support pre-cached set of crates that can be vendored.
- Support pre-filled cargo registry.
- Support further tools like cargo-fmt, cargo-clippy, GDB support and so
on.

Needed when compiling with options such as "-C profile-generate" or
"-Z instrument-coverage", e.g. when generating coverage reports or doing
profile guided optimization.
Building for "+v8.1a" breaks on (at least) Cortex A53 (Armv8-A) on
startup with `Illegal instruction`.
Fixes: 26609f46d9 ("rust.inc: use 'v8.1a' feature when building for aarch64 instead of 'v8'")
* get rid of annoying
'+v8' is not a recognized feature for this target (ignoring feature)
messages in aarch64 builds, they are shown in the log very often:
$ grep -c 'is not a recognized feature for this target (ignoring feature)' cargo/1.49.0-r0/temp/log.do_compile.76960
3824
and sometimes the formatting looks strange as well e.g.:
| ''+v8' is not a recognized feature for this target (ignoring feature)
| +v8' is not a recognized feature for this target (ignoring feature)
| '+v8' is not a recognized feature for this target (ignoring feature)

* not sure when it was changed (if 'v8' ever was valid feature for aarch64)

Normally all *-native packages needs to depend on cargo-native in order
to be able to use cargo. When building cargo-native however, this is not
available and we use a snapshot.
Fixes#302.
* move common stuff from rust-source to rust.inc and from rust-snapshot to rust-target.inc
* 1.34.2 checksums were changed because unified SRC_URI is using tar.xz
for this version as well (instead of tar.gz used before here)

* rust-llvm.inc sets LICENSE and corresponding LIC_FILES_CHKSUM
for Apache-2.0-with-LLVM-exception, but the recipes which include
rust-llvm-ncsa.inc need to change it to NCSA.
