* Speed up buffer.swap16 and swap32 by using builtins. Up to ~6x gain.
Drop transition point between JS and C++ implementations accordingly.
Amount of performance improvement not only depends on buffer size but
also memory alignment.
* Fix tests: C++ impl tests were testing 0-filled buffers so were
always passing.
* Add similar buffer.swap64 method.
* Make buffer-swap benchmark mirror JS impl.
doc/api/buffer.markdown has an entry of "added: REPLACEME" that should
be changed to the correct release number before tagged.
Because node is currently using a very old version of cpplint.py it
doesn't know that std::swap() has moved from <algorithm> to <utility> in
c++11. So until cpplint.py is updated simply NOLINT the line.
Technically it should be NOLINT(build/include_what_you_use), but that
puts the line over 80 characters causing another lint error.

When node began using the OneByte API (f150d56) it also switched to
officially supporting ISO-8859-1. Though at the time no new encoding
string was introduced.
Introduce the new encoding string 'latin1' to be more explicit. The
previous 'binary' and documented as an alias to 'latin1'. While many
tests have switched to use 'latin1', there are still plenty that do both
'binary' and 'latin1' checks side-by-side to ensure there is no
regression.

* Remove unnecessary templating from SearchString
SearchString used to have separate PatternChar and SubjectChar template type
arguments, apparently to support things like searching for an 8-bit string
inside a 16-bit string or vice versa. However, SearchString is only used from
node_buffer.cc, where PatternChar and SubjectChar are always the same. Since
this is extra complexity that's unused and untested (simplifying to a single
Char template argument still compiles and didn't break any unit tests), I
removed it.
* Use Boyer-Hoore[-Horspool] for both indexOf and lastIndexOf
Add test cases for lastIndexOf. Test the fallback from BMH to
Boyer-Moore, which looks like it was totally untested before.

Can now call fill() using following parameters if value is a String:
fill(string[, start[, end]][, encoding])
And with the following if value is a Buffer:
fill(buffer[, start[, end]])
The encoding is ignored if value is not a String. All other non-Buffer
values are coerced to a uint32.
A multibyte strings will simply be copied into the Buffer until the
number of bytes run out. Meaning partial strings can be left behind:
Buffer(3).fill('\u0222');
// returns: <Buffer c8 a2 c8>
In some encoding cases, such as 'hex', fill() will throw if the input
string is not valid.

Known issues:
* Not every JSON / object notation has been improved. Should
make another run for this.
* Some example functions break hightlighting due to various

When v8 implemented proper one-byte string support Node's internal
"binary" encoding implementation was removed in favor of it. The result
was that "binary" encoding effectively became "latin-1" encoding.
Because of this and because one-byte strings are natively supported by
v8 the buffer encoding is not deprecated and will not be removed.
