Rect types.

The actual image representation is unchanged. A future change will
replace the {[][]color} with {[]color, stride int, r Rectangle} and
possibly a clip region.

The draw.Color, draw.Point and draw.Rect types will be removed in a
future change. Trying to do it in this one polluted the diff with
trivia.

Fixed:
* SetString calls in bitwise tests
* Aliasing problem with self bitwise test
* One test case that was just flat out wrong
* Slice panics in nat.or and nat.xor
* Aliasing problems in Int.And, Int.AndNot, Int.Or, Int.Xor

Generic text-based network protcol library for SMTP-like protocols.
HTTP and NNTP should be changed to use this package,

- float comparisons involving NaNs work

Basically these functions are implemented the same way as the
corresponding functions in the strings package.  Test functions
are implemented for IndexRune and FieldsFunc.

Additionally two typos are fixed in packages bytes and strings.

This implementation is simpler and more useful, since it can work

Plays more nicely with ELF ABI C code.
In particular, our signal handlers will no longer crash
when a signal arrives during execution of a cgo C call.
