incr.comp.: Don't crash in DepGraph::try_mark_green() when encountering a removed input node.
Fixes a small regression that was introduced in #45867.

This changes macro expansion to format the path of a macro directly
instead of usng the pprust infrastructure. The pprust infrastructure
tries to perform line-breaking in a slow fashion, which is undesired
when formatting the path of a macro.
This should to speed up expansion by a fair amount (I saw 20% on a
profiler on `rustc_mir`, and 50% of the time marked as "expansion" in
the profiler/time-passes is actually spent loading dependencies).
check::method - unify receivers before normalizing method signatures
Normalizing method signatures can unify inference variables, which can
cause receiver unification to fail. Unify the receivers first to avoid
that.
Fixes#36701.
Fixes#45801.
Fixes#45855.

beta-nominating because #43880 made this ICE happen in more cases (the code in that issue ICEs post-#43880 only, but the unit test here ICEs on all versions).
On some systems, the bash command could be available in another
directory than /bin. As such, to offer an env shebang is more
convenient.
This make sense even for docker scripts, as you can use Docker
on FreeBSD or SmartOS for example.
deduplicate projection error (E0271) messages
The `ErrorId` variant takes a u16 so that `DiagnosticMessageId` can retain
its `Copy` status (the present author's first choice having been the "EXXX"
code as a string).
The duplicated "type mismatch resolving `{}`" literal is unfortunate, but
the `struct_span_err!` macro (which we want to mark that error code as
used) is fussy about taking a literal, and the one-time-diagnostics set
needs an owned string.
This is concerning #33941 and probably #45805!

MIR-borrowck: fix diagnostics for closures
Emit notes for captured variables in the same manner as AST borrowck.

compiletest: Fix a couple of test re-run issues
* Re-run rustdoc tests if rustdoc or htmldocck.py was updated.
* Put stamp files in the correct subdirectories to avoid clashes when
the file names match but the subdirectory doesn't.
Fix test case header parsing code in presence of multiple revisions.
The previous code would parse the TestProps, and then parse them again with a revision set, adding some elements (like aux_builds) a second time to the existing TestProps.
Redox: Use futex timeout to implement CondVar::wait_timeout
`CondVar::wait_timeout` is implemented by supplying a `TimeSpec` pointer to `futex`. In addition, all calls to `unimplemented!()` have been removed from the Redox `sys` module.

Redox: Return true from Path::is_absolute if a Path contains root or a scheme
In Redox, different subsystems have different filesystem paths. However, the majority of applications using the `Path::is_absolute` function really only want to know if a path is absolute from the perspective of the scheme it is currently running in, usually `file:`. This makes both `file:/` and `/` return `true` from `Path::is_absolute`, meaning that most code does not have to check if it is running on Redox.
Code that wants to know if a path contains a scheme can implement such a check on its own.

Bump cargo to master
Includes a few bugfixes, and updates the Cargo book.
Critically includes https://github.com/rust-lang/cargo/pull/4716. This
unblocks (in theory) crater runs.
Improve SubSupConflict with a named and an anonymous lifetime parameter #42701
Hello!
This fixes#42701.
## UPDATE 01
Tests are producing different results between different env builds.
This inconsistency might take a long time to investigate and fix. So, be patient
## UPDATE 02
Changed an `FxHashMap` with a `BTreeMap`. Inconsistency seems to be resolved for now.
