If it's a trait method, this checks the stability attribute of the
method inside the trait definition. Otherwise, it checks the method
implementation itself.
This replaces the link meta attributes with a pkgid attribute and uses a hash
of this as the crate hash. This makes the crate hash computable by things
other than the Rust compiler. It also switches the hash function ot SHA1 since
that is much more likely to be available in shell, Python, etc than SipHash.
Fixes#10188, #8523.

This bug showed up because the visitor only visited the path of the implemented
trait via walk_path (with no corresponding visit_path function). I have modified
the visitor to use visit_path (which is now overridable), and the privacy
visitor overrides this function and now properly checks for the privacy of all
paths.
Closes#10857
**Note**: I only tested on top of my #10670 PR, size reductions come from both change sets.
With this, [more enums are shrinked](https://gist.github.com/eddyb/08fef0dfc6ff54e890bc), the most significant one being `ast_node`, from 104 bytes (master) to 96 (#10670) and now to 32 bytes.
My own testcase requires **200MB** less when compiling (not including the other **200MB** gained in #10670), and rustc-stage2 is down by about **130MB**.
I believe there is more to gain by fiddling with the enums' layouts.
Instead of forcibly always aborting compilation, allow usage of
#[warn(unknown_features)] and related lint attributes to selectively abort
compilation. By default, this lint is deny.

I've started working on this issue and pushed a small commit, which adds a range check for integer literals in `middle::const_eval` (no `uint` at the moment)
At the moment, this patch is just a proof of concept, I'm not sure if there is a better function for the checks in `middle::const_eval`. This patch does not check for overflows after constant folding, eg:
let x: i8 = 99 + 99;
