This commit moves the libserialize crate (and will force the hand of the
rustc-serialize crate) to not require the `old_orphan_check` feature gate as
well as using associated types wherever possible. Concretely, the following
changes were made:
* The error type of `Encoder` and `Decoder` is now an associated type, meaning
that these traits have no type parameters.
* The `Encoder` and `Decoder` type parameters on the `Encodable` and `Decodable`
traits have moved to the corresponding method of the trait. This movement
alleviates the dependency on `old_orphan_check` but implies that
implementations can no longer be specialized for the type of encoder/decoder
being implemented.
Due to the trait definitions changing, this is a:

The casing transformations are left unstable (it is highly likely to be better to adopt the proper non-1-to-1 case mappings, per #20333) as are `is_xid_*`.
I've got a little todo list in the last commit of things I thought about/was told about that I haven't yet handled (I'd also like some feedback).
This commit introduces the syntax for negative implementations of traits
as shown below:
`impl !Trait for Type {}`

This "reexports" all the functionality of `core::char::CharExt` as
methods on `unicode::u_char::UnicodeChar` (renamed to `CharExt`).
Imports may need to be updated (one now just imports
`unicode::CharExt`, or `std::char::CharExt` rather than two traits from
either), so this is a

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.
