I've been working with some archives generated by MSVC's `lib.exe` tool lately,
and it looks like the embedded name of the members in those archives sometimes
have slahes in the name (e.g. `foo/bar/baz.obj`). Currently the compiler chokes
on these paths as it assumes that each file in the archive is only the filename
(which is what unix does).
This commit interprets the name of each file in all archives as a path and then
only uses the `file_name` portion of the path to extract the file to a separate
location and then reassemble it back into a new archive later. Note that
duplicate filenames are already handled, so this won't introduce any conflicts.
This fixes#24922 and #25017, and reduces the number of error messages that talk about "methods" when associated constants rather than methods are involved.
I will admit that I haven't thought very carefully about the error messages. My goal has been to make more of the messages technically correct in all situations, and to avoid ICEs. But in some cases we could probably talk specifically about "methods" rather than "items".

I just noticed this while talking to someone who was using
`os.environ['FOO'] = 'BAR'` in Python and since I'm learning Rust, I
was curious if it did anything special here. It looks like Rust has
an internal mutex, which helps for apps that are pure Rust, but it
will be an evil trap for someone later adding in native code (apps
like Servo and games will be at risk).
Java got this right by disallowing `setenv()` from the start.
I suggest Rust program authors only use `setenv()` early in main.
This also updates the error messages for both. For E0066, it removes mention
of "managed heap", which was removed in 8a91d33. For E0069, I just tweaked
the wording to make it a bit more explicit.
This commit is an implementation of [RFC 1040][rfc] which is a redesign of the
currently-unstable `Duration` type. The API of the type has been scaled back to
be more conservative and it also no longer supports negative durations.
[rfc]: https://github.com/rust-lang/rfcs/blob/master/text/1040-duration-reform.md
The inner `duration` module of the `time` module has now been hidden (as
`Duration` is reexported) and the feature name for this type has changed from
`std_misc` to `duration`. All APIs accepting durations have also been audited to
take a more flavorful feature name instead of `std_misc`.
Closes#24874
The code takes a prefix of the MD5 hash of the version string.
Since the hash command differs across GNU and BSD platforms, we scan for
the right one in the configure script.
Closes#25007
Also change several error messages to refer to "items" rather than
"methods", since associated items that require resolution during type
checking are not always methods.
