Clarify the doc index
With regards to the unstable book, the reference, and the
processes involved.
Also, fix up a link by pointing to the new tracking issue rather than
the older one.

Specify behavior of `write_all` for `ErrorKind::Interrupted` errors
Also spell out that read and write operations should be retried on
`ErrorKind::Interrupted` errors.
Fixes#38494.
Adds rust-windbg.cmd script
Adds rust-gdb/rust-lldb equivalent for windbg that loads the Rust .natvis files on start.
This change modifies the bootstrap code to add rust-windbg to bin and the .natvis files to lib/rustlib/etc.
Example usage from cmd or PowerShell:
```
rust-windbg -c "bu rs_f442289d74765418!rs::main;g" target\debug\rs.exe
```
Check privacy of trait items in all contexts
Fixes https://github.com/rust-lang/rust/issues/28514
This is a sufficiently rare scenario and it's currently guarded by `private_in_public` lint, so it shouldn't be a [breaking-change] in practice.
Run tests for the cargo submodule in tree
Previously the `cargotest` suite would run some arbitrary revision of Cargo's
test suite, but now that we're bundling it in tree we should be running the
Cargo submodule's test suite instead.
Implement Vec::splice and String::splice (RFC 1432)
RFC: rust-lang/rfcs#1432, tracking issue: #32310
A rebase of https://github.com/rust-lang/rust/pull/32355 with a few more tests.
Let me know if you have any ideas for more tests.

Fixes#41285
ASan and TSan are supported on macOS, and this commit enables their
support.
The sanitizers are always built as *.dylib on Apple platforms, so they
cannot be statically linked into the corresponding `rustc_?san.rlib`. The
dylibs are directly copied to `lib/rustlib/x86_64-apple-darwin/lib/`
instead.
Note, although Xcode also ships with their own copies of ASan/TSan dylibs,
we cannot use them due to version mismatch.
There is a caveat: the sanitizer libraries are linked as @rpath, so the
user needs to additionally pass `-C rpath`:
rustc -Z sanitizer=address -C rpath file.rs
^~~~~~~~
Otherwise there will be a runtime error:
dyld: Library not loaded: @rpath/libclang_rt.asan_osx_dynamic.dylib
Referenced from: /path/to/executable
Reason: image not found
Abort trap: 6
The next commit includes a temporary change in compiler to force the linker
to emit a usable @rpath.
