A major discoverability issue with rustdoc is that all crates have their
documentation built in isolation, so it's difficult when looking at the
documentation for libstd to learn that there's a libcollections crate with a
HashMap in it.
This commit moves rustdoc a little closer to improving the multiple crate
experience. This unifies all search indexes for all crates into one file so all
pages share the same search index. This allows searching to work across crates
in the same documentation directory (as the standard distribution is currently
built).
This strategy involves updating a shared file amongst many rustdoc processes, so
I implemented a simple file locking API for handling synchronization for updates
to the shared files.
cc #12554
This patch replaces all `crate` usage with `krate` before introducing the
new keyword. This ensures that after introducing the keyword, there
won't be any compilation errors.
krate might not be the most expressive substitution for crate but it's a
very close abbreviation for it. `module` was already used in several
places already.
rustdoc:
- fix search-bar layout
doc: CSS:
- switch to native pandoc toc depth
- rm some dead code
- clamp width to be readable (we're not Wikipedia!)
- don't background-color titles, it's bloating
- make syntax-highlighting colors inline with rust-lang.org
- space indents

All items have source links back to their actual code. Source files can be
omitted with the doc(html_no_source) attribute on the crate. Currently there is
no syntax highlighting, but that will come with syntax highlighting with all
other snippets.
Closes#2072
Removes old rustdoc, moves rustdoc_ng into its place instead (plus drops the _ng
suffix). Also shreds all reference to rustdoc_ng from the Makefile rules.
