rustdoc: escape shown input to prevent injection
libsyntax: Add `box PAT` to the pattern grammar. RFC #14.
Refactor `rslt` to `Result::new`
shootout-mandelbrot rewrite

- removed warning
- improved performances
- parallelization
Temporary patch to accept arbitrary lifetimes (behind feature gate) in bound lists. This is needed to bootstrap fix for #5723.
Remove comment about semicolons for inner attributes from docs and adjust comments.
shootout-spectralnorm tweaks

- using libgreen to optimize CPU usage
- less tasks to limit wasted resources

Here, on a one core 2 threads CPU, new version is ~1.2 faster.  May
be better with more core.
