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.

[breaking-change]
The `Index[Mut]` traits now have one less input parameter, as the return type of the indexing operation is an associated type. This breaks all existing implementations.
---
binop traits (`Add`, `Sub`, etc) now have an associated type for their return type. Also, the RHS input parameter now defaults to `Self` (except for the `Shl` and `Shr` traits). For example, the `Add` trait now looks like this:
``` rust
trait Add<Rhs=Self> {
type Output;
fn add(self, Rhs) -> Self::Output;
}
```
The `Neg` and `Not` traits now also have an associated type for their return type.
This breaks all existing implementations of these traits.
---
Affected traits:
- `Iterator { type Item }`
- `IteratorExt` no input/output types, uses `<Self as Iterator>::Item` in its methods
- `DoubleEndedIterator` no input/output types, uses `<Self as Iterator>::Item` in its methods
- `DoubleEndedIteratorExt` no input/output types, uses `<Self as Iterator>::Item` in its methods
- `RandomAccessIterator` no input/output types
- `ExactSizeIterator` no input/output types, uses `<Self as Iterator>::Item` in its methods
This breaks all the implementations of these traits.
