This makes the `u16` in `Quality` private, since it only has a valid
range of 0-1000, and can't be enforced in public. The `q` function now
allows both `f32`s and `u16`s to construct a `Quality`.
BREAKING CHANGE: Any use of `Quality(num)` should change to `q(num)`.
1. index out of bounds if semicolon is the last character
2. not a char boundary on non-ASCII input (only allow ASCII now)

The new macro handles single value headers, list headers, and list
headers with at least one item.
It creates the item for the header and contains its documentation. The
new macro allows handling
more header cases in the future, it will also be possible to include
tests inside the macro.
BREAKING CHANGE: Removed impl_header!() and impl_list_header!() macros,
use new header!() macro.
Using floating point numbers is problematic because comparison is inexact.
They also take more space than integral numbers in this case.
Add `FromPrimitve`, `ToPrimitive` and `Default` traits to quality newtype.
Closes: #330
BREAKING_CHANGE: Replace f32 quality values in quality items with a
Quality(u16) newtype. Valid values are from 0 to 1000.
It is no longer required, as we can use `<H as Header>::header_name()`.
BREAKING CHANGE: Implementations of Header will need to adjust the
header_name method. It no longer takes any arguments.
Currently headers are exported at many places. For example you can access
`Transfer-Encoding` header at `header`, `header::common` and
`header::common::transfer_encoding`. Per discussion on IRC with
@seanmonstar and @reem, all contents of headers will be exposed at `header`
directly. Parsing utilities will be exposed at `header::parsing`. Header
macros can now be used from other crates.
This breaks much code using headers. It should use everything it needs
directly from `header::`, encodings are exposed at `header::Encoding::`,
connection options are exposed at `header::ConnectionOption`.
