Reject feature flags in a virtual workspace. This generates an error if feature flags are used in the root of a virtual workspace. Previously these flags were completely ignored. In the interest of avoiding confusion, I think it would be good to be explicit that these don't currently work. This could alternatively be a warning, but I think it is better to reject it outright. cc #4753, #3620, #5015, #6195, etc.

…hton Allow --all-features in root of virtual workspace. Accidentally restricted in #7507, pointed out by @hjmallon, `--all-features` flag is allowed in the root of a virtual workspace. Added a test to demonstrate its strange behavior. For anyone that is curious, [this line](https://github.com/rust-lang/cargo/blob/3a9abe3f065554a7fbc59f440df2baba4a6e47ee/src/cargo/ops/resolve.rs#L302) is the code responsible for this behavior.

Version 1.40.0 (2019-12-19)
===========================
Language
--------
- [You can now use tuple `struct`s and tuple `enum` variant's constructors in
`const` contexts.][65188] e.g.
```rust
pub struct Point(i32, i32);
const ORIGIN: Point = {
let constructor = Point;
constructor(0, 0)
};
```
- [You can now mark `struct`s, `enum`s, and `enum` variants with the `#[non_exhaustive]` attribute to
indicate that there may be variants or fields added in the future.][64639]
For example this requires adding a wild-card branch (`_ => {}`) to any match
statements on a non-exhaustive `enum`. [(RFC 2008)]
- [You can now use function-like procedural macros in `extern` blocks and in
type positions.][63931] e.g. `type Generated = macro!();`
- [Function-like and attribute procedural macros can now emit
`macro_rules!` items, so you can now have your macros generate macros.][64035]
- [The `meta` pattern matcher in `macro_rules!` now correctly matches the modern
attribute syntax.][63674] For example `(#[$m:meta])` now matches `#[attr]`,
`#[attr{tokens}]`, `#[attr[tokens]]`, and `#[attr(tokens)]`.
Compiler
--------
- [Added tier 3 support\* for the
`thumbv7neon-unknown-linux-musleabihf` target.][66103]
- [Added tier 3 support for the
`aarch64-unknown-none-softfloat` target.][64589]
- [Added tier 3 support for the `mips64-unknown-linux-muslabi64`, and
`mips64el-unknown-linux-muslabi64` targets.][65843]
\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.
Libraries
---------
- [The `is_power_of_two` method on unsigned numeric types is now a `const` function.][65092]
Stabilized APIs
---------------
- [`BTreeMap::get_key_value`]
- [`HashMap::get_key_value`]

Cargo
-----
- [Cargo will now always display warnings, rather than only on
fresh builds.][cargo/7450]
- [Feature flags (except `--all-features`) passed to a virtual workspace will
now produce an error.][cargo/7507] Previously these flags were ignored.
- [You can now publish `dev-dependencies` without including
a `version`.][cargo/7333]
Misc
----
- [You can now specify the `#[cfg(doctest)]` attribute to include an item only
when running documentation tests with `rustdoc`.][63803]
Compatibility Notes
-------------------
- [As previously announced, any previous NLL warnings in the 2015 edition are
now hard errors.][64221]
- [The `include!` macro will now warn if it failed to include the
entire file.][64284] The `include!` macro unintentionally only includes the
first _expression_ in a file, and this can be unintuitive. This will become
either a hard error in a future release, or the behavior may be fixed to include all expressions as expected.
- [Using `#[inline]` on function prototypes and consts now emits a warning under
`unused_attribute` lint.][65294] Using `#[inline]` anywhere else inside traits
or `extern` blocks now correctly emits a hard error.

This generates an error if feature flags are used in the root of a virtual workspace. Previously these flags were completely ignored. In the interest of avoiding confusion, I think it would be good to be explicit that these don't currently work. This could alternatively be a warning, but I think it is better to reject it outright.
