config.mk is now always read when parsing the configuration to prevent
this from reoccurring in the future, hopefully.
Replaced by adding extra imports, adding hidden code (`# ...`), modifying
examples to be runnable (sorry Homura), specifying non-Rust code, and
converting to should_panic, no_run, or compile_fail.

Remaining "```ignore"s received an explanation why they are being ignored.
Display actual args instead of two dots.
When bootstrap is executed with python not in `$PATH`, (e. g.
`c:\Python27\python.exe x.py test`) bootstrap cannot find python
and crashes.

This commit passes path to python in `BOOTSTRAP_PYTHON` env var.
Rustbuild passes --message-format=json to Cargo to learn about the
dependencies for a given build, which then makes Cargo steal the
stderr/stdout for the compiler process, leading to non colorful output.
To avoid this, detection of stderr being a tty is added to rustbuild,
and an environment variable is used to communicate with the rustc shim.
Add support for `-Z force-unstable-if-unmarked` to rustdoc.

Remove most "```ignore" doc tests.

Unconditional ` ```ignore ` doc tests lead to outdated examples (e.g. rust-lang#42729 (comment)). This PR tries to change all existing ` ```ignore ` tests into one of the following:

* Add import and declarations to ensure the code is run-pass
* If the code is not Rust, change to ` ```text `/` ```sh `/` ```json `/` ```dot `
* If the code is expected compile-fail, change to ` ```compile_fail `
* If the code is expected run-fail, change to ` ```should_panic `
* If the code can type-check but cannot link/run, change to ` ```no_run `
* Otherwise, add an explanation after the ` ```ignore `

The `--explain` handling is changed to cope with hidden lines from the error index.

Tidy is changed to reject any unexplained ` ```ignore ` and ` ```rust,ignore `.

Better Debug for Args and ArgsOs

Impl Clone for DefaultHasher

It's useful for a hasher to be `Clone`. It's also strange for any type to not be `Clone`. `DefaultHasher` is not meant to be used directly, but being in std it can be useful as a placeholder. I don't see any forward compatibility hazard if the hasher is changed since it's very rare for something to not be `Clone`.

Make rustc errors colorful.

Rustbuild passes --message-format=json to Cargo to learn about the
dependencies for a given build, which then makes Cargo steal the
stderr/stdout for the compiler process, leading to non colorful output.
To avoid this, detection of stderr being a tty is added to rustbuild,
and an environment variable is used to communicate with the rustc shim.

Fixes rust-lang#42801.

Pass path to python from bootstrap.py to bootstrap.rs

When bootstrap is executed with python not in `$PATH`, (e. g.
`c:\Python27\python.exe x.py test`) bootstrap cannot find python
and crashes.

This commit passes path to python in `BOOTSTRAP_PYTHON` env var.

rustbuild: Fix compiler docs yet again

Fixing basic typos in Doc Comments

Files checked : *.rs files inside 'src' directory.

Only Doc comments (/// and //!) are fixed.

Note: the non American-English spellings are left unchanged.

Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @arielb1 (or someone else) soon.

If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes.

Please see the contribution instructions for more information.
