This commit introduces the syntax for negative implementations of traits
as shown below:
`impl !Trait for Type {}`
cc #13231
Part of RFC rust-lang/rfcs#127

TODOs:
- ~~Entry is still `<'a, K, V>` instead of `<'a, O, V>`~~
- ~~BTreeMap is still outstanding~~.
- ~~Transform appropriate things into `.entry(...).get().or_else(|e| ...)`~~
Things that make me frowny face:
- I'm not happy about the fact that this `clone`s the key even when it's already owned.
- With small keys (e.g. `int`s), taking a reference seems wasteful.

Use autoderef for call notation. This is consistent in that we now autoderef all postfix operators (`.`, `[]`, and `()`). It also means you can call closures without writing `(*f)()`. Note that this is rebased atop the rollup, so only the final commit is relevant.

After 8b3c67690c the `make install`
command fails if docs are not disabled through CFG_DISABLE_DOCS,
because now the `install` target uses
../../tmp/dist/$(DOC_PKG_NAME)-$(CFG_BUILD)/install.sh
Instead of explicitly depending on
dist/$(PKG_NAME)-$(CFG_BUILD).tar.gz, the `prepare_[un]install`
targets now depend on `dist-tar-bins`, which packages the appropriate
dist archives depending on the configuration.
This removes a large array of deprecated functionality, regardless of how
recently it was deprecated. The purpose of this commit is to clean out the
standard libraries and compiler for the upcoming alpha release.
Some notable compiler changes were to enable warnings for all now-deprecated
command line arguments (previously the deprecated versions were silently
accepted) as well as removing deriving(Zero) entirely (the trait was removed).
The distribution no longer contains the libtime or libregex_macros crates. Both
of these have been deprecated for some time and are available externally.
