Bring more attention to short reads/slices on Buff/BuffMut ( #231 )
...
The property the Buff and BuffMut can return shorter slice is quite an
important detail. Nevertheless, while it is mentioned in the
documentation, the wording makes it relatively easy to overlook. This
tries to bring more attention to it.

Improve performance of Buf::get_*() ( #195 )
...
The new implementation tries to get the data directly from bytes() (this is
possible most of the time) and if there is not enough data in bytes() use the
previous code: copy the needed bytes in a temporary buffer before returning
the data
Here the bench results:

Improvement on the basic std::Cursor implementation are clearly visible.
Other implementations are specific to the bench tests and just map a static
slice. Different variant are:
- tbuf_1: only one call of 'bytes()' is needed.
- tbuf_2: two calls of 'bytes()' is needed to read more than one byte.
- _costly version are implemented with #[inline(never)] on 'bytes()',
'remaining()' and 'advance()'.
The cases that are slower (slightly) correspond to implementations that are not
really realistic: more than one byte is never possible in one time

Fix copy_to_slice to use correct increment var
...
This patch fixes the `copy_to_slice` function, rectifying the logic.
However, the incorrect code does not result in incorrect behavior as the
only case `cnt != src.len()` is during the final iteration, and since
`src.len()` is greater than `cnt` in that case, `off` will be
incremented by too much, but this will still trigger the `off <
dst.len()` condition.
The only danger is `src.len()` could cause an overflow.

Remove ByteOrder generic methods from Buf and BufMut ( #187 )
...
* make Buf and BufMut usable as trait objects
- All the `get_*` and `put_*` methods that take `T: ByteOrder` have
a `where Self: Sized` bound added, so that they are only usable from
sized types. It was impossible to make `Buf` or `BufMut` into trait
objects before, so this change doesn't break anyone.
- Add `get_n_be`/`get_n_le`/`put_n_be`/`put_n_le` methods that can be
used on trait objects.
- Deprecate the export of `ByteOrder` and methods generic on it.
* remove deprecated ByteOrder methods
Removes the `_be` suffix from all methods, implying that the default
people should use is network endian.

Remove buf::Source in favor of buf::IntoBuf
...
The `Source` trait was essentially covering the same case as `IntoBuf`,
so remove it.
While technically a breaking change, this should not have any impact due
to:
1) There are no reverse dependencies that currently depend on `bytes`
2) Source was not supposed to be implemented externally
3) IntoBuf provides the same implementations as `Source`
Given these points, the change should be safe to apply.
