@jongiddy noticed bad performance due to the lack of inlining on `then`
and `then_with`. I confirmed that inlining really is the culprit by
creating a custom `then` function and repeating his benchmark on my
machine with and without the `#[inline]` attribute.
The numbers were exactly the same on my machine without the attribute.
With `#[inline]` I got the same performance as I did with manually
inlined implementation.
Their relationship is:
* `resume_from = error_len.map(|l| l + valid_up_to)`
* error_len is always one of None, Some(1), Some(2), or Some(3).
When I started using resume_from I almost always ended up subtracting
valid_up_to to obtain error_len.
Therefore the latter is what should be provided in the first place.
We don't want a dynamic dependency in the library that we ship, so link it
statically by configuring curl-sys's build script to not pick up the system
version via pkg-config.
Primarily opened to address the concerns brought up in
https://github.com/rust-lang/rust/issues/40498.
* run rustfmt on code blocks
* use `DefaultHasher` instead of deprecated `SipHasher`
* rename `hash` to `calculate_hash` to prevent confusion with the `hash`
method
rustdoc: Fix string escaping in implementors js files
The generated HTML can contain quotes so we need to make sure they are
escaped before inserting into the js files.
rustbuild: Fix compiler docs
* Make sure std docs are generated before compiler docs so rustdoc uses
relative links.
* Don't document the rustc and rustdoc binary crates as they overwrite
the real rustc and rustdoc crates.

Update Cargo to fix nightly channel
This commit updates Cargo with rust-lang/cargo#3820 which includes a fix for
rust-lang/cargo#3819. At the same time this also slightly tweaks how rustbuild
builds cargo to ensure that all the build information (including git info and
such) makes its way into the binary.
Closesrust-lang/cargo#3819

Update mdbook to new version
This brings back playpen integration for the books.
It'd be nice to land this before beta, but realistically that's probably not going to happen...
LLVM: Update submodule to include SRet support patch for MSP430.
This patch is needed to fix#38824 on MSP430.
I know that LLVM 4 is coming soon, but it would be great to have at least one working nightly before the update.
