Release v1.1.0

Improved Support for Adding New Types
-------------------------------------

The primary focus of this release was improving the ergonomics of adding
support for new types in Diesel.

For implementing new SQL types, we've added `#[derive(SqlType)]` which
implements many traits that you need to implement for every SQL type.
See the documentation for `HasSqlType` for details on this derive.

For implementing new mappings, we've added `#[derive(FromSqlRow)]` and
`#[derive(AsExpression)]`. These derives will replace the majority of
the boilerplate that was previously required when supporting new types.
Adding support for new types in Diesel 1.1 should only require
implementing `FromSql` and `ToSql`. The derives will handle the rest.

We've also provided `FromSql` impls for `*const str` and `*const [u8]`.
Due to the design of `FromSql`, we can't provide impls for `&str` and
`&[u8]` without a breaking change. However many impls just need to parse
a string or some bytes, and don't need the allocation that would come
from `String` or `Vec<u8>`. This will require unsafe code to use, but
should make certain implementations more efficient.

Finally, we've restructured how our serialize/deserialize modules are
structured, and provided type aliases to make implementations of
`FromSql` and `ToSql` more consise.

`r2d2_diesel` is Now Part of Diesel
-----------------------------------

Finally, this release merges `r2d2_diesel` into Diesel itself. The main
benefit of doing this is that we can implement `Connection` for
`PooledConnection`, removing the need for explicit `&*` when using r2d2.
This should also help to prevent version mismatches when changing Diesel
versions.

To use the new r2d2 support, remove `r2d2` and `r2d2_diesel` from your
Cargo.toml. Add the `r2d2` to your enabled features on `diesel`. Replace
`extern crate r2d2` with `pub use diesel::r2d2`. Replace any
`r2d2_diesel::` with `diesel::r2d2::`.
