[v4] Rust Oe-Selftest implementation

The patch implements Rust testing framework similar to other selftest,
specifically the gcc selftest in OE. It uses the client and server
based method to test the binaries for cross-target on the image.
The test framework is a wrapper around the Rust build system as ./x.py test.
It tests many functionalities of Rust distribution like tools,
documentation, libraries, packages, tools, Cargo, Crater etc.
Please refer the following link for detailed description of Rust
testing:-
https://rustc-dev-guide.rust-lang.org/tests/intro.html#tool-tests

To support the rust tests in oe-core, the following functions were
added:-
setup_cargo_environment(): Build bootstrap and some early stage tools.
do_rust_setup_snapshot(): Install the snapshot version of rust binaries.
do_configure(): To generate config.toml
do_compile(): To build "remote-test-server" for qemu target image.

Approximate Number of Tests Run in the Rust Testsuite :- 18000
Approximate Number of Tests that FAIL in bitbake environment :- 100-150
Normally majority of the testcases are present in major folder "test/"
It contributes to more than 80% of the testcases present in Rust test
framework. These tests pass as expected on any Rust versions without
much fuss. The tests that fail are of less important and contribute to
less than 2% of the total testcases. These minor tests are observed to
work on some versions and fail on others. They have to be added, ignored
or excluded for different versions as per the behavior.
These tests have been ignored or excluded in the Rust selftest environment
to generate success of completing the testsuite.

With Rust-1.54.0 only 4 test modules were excluded (rustc-main, tiny).
However with Rustc-1.58.1 the following issue required excluding many more
test modules.
These tests can be included in Oe-selftest after fixing the issue.
===============================================================
"build-st/tmp/work/core2-64-poky-linux/rust-testsuite/1.58.1-r0/
rustc-1.58.1-src/build/bootstrap/debug/rustc -vV` (exit status: 101)
--- stderr
thread 'main' panicked at '
kind: NotFound, message: "No such file or directory" }',
src/bootstrap/bin/rustc.rs:175:37
===============================================================
It mentions that the rustc binary is not present inspite of it being present.

There are many tests in Rust which just checks the documents, formatting,
documentation etc. These tests can be ignored and not run as some FAILS
most of the times.

These tests work in parallel mode even in the skipped test mode as expected.
Although the patch to disable tests is large, it is very simple in that it
only disables tests. When updating to a newer version of Rust, the patch can
usually be rebased in under a day.

To give people some context for the tests, the output format is:

running 12415 tests
test [ui] ui/abi/stack-protector.rs#no-ssp ... ignored
test [ui] ui/abi/stack-protector.rs#ssp ... ignored
...
test [ui] ui/asm/x86_64/interpolated-idents.rs ... ok
test [ui] ui/asm/x86_64/bad-clobber-abi.rs ... ok
test [ui] ui/assign-imm-local-twice.rs ... ok

...


Filtering that:
$ rg "test \[" /tmp/oe-selftest-results-1-b.log | cut -d" " -f2 | uniq -c

     133 [assembly]
     305 [codegen]
      42 [codegen-units]
     150 [incremental]
     166 [mir-opt]
      70 [pretty]
      17 [run-pass-valgrind]
     485 [rustdoc]
   12483 [ui]

and in alphabetical order, the overall summary is:

$ rg "test \[" /tmp/oe-selftest-results-1-b.log | cut -d" " -f2 | sort | 
uniq -c

     133 [assembly]
     305 [codegen]

     166 [mir-opt]
      70 [pretty]
      17 [run-pass-valgrind]
     485 [rustdoc]
   12483 [ui]

and expanding to get, not only the number of tests, but also the test 
result:

$ rg "test \[" /tmp/oe-selftest-results-1-b.log | rg -v " should" | cut 
-d" " -f2,5 | sort | uniq -c

      29 [assembly] ignored
     104 [assembly] ok

      70 [pretty] ok
      17 [run-pass-valgrind] ok
      71 [rustdoc] FAILED
      56 [rustdoc] ignored
     354 [rustdoc] ok
      12 [ui] FAILED
     150 [ui] ignored
   12317 [ui] ok

Note the 'should' filter omits 10 tests that didn't fit my filter such as:
       test [ui] ui/loud_ui.rs - should panic ... ok
that I didn't want to deal with.


I'm not sure if the FAILED tests should be skipped here but it looks 
like it is failing:

Naveen,

Am I looking at the right log file? ( 
.../ngowda/.../oe-selftest/oe-selftest-results-1.log )

Also, when you have time, can you find out if the test that are 
"ignored" in our environment
are also ignore when building natively?


Thanks for updating the commit log, it is better.
