This implements a replacer for when all old strings are single
bytes, but new values are not.

When all old & new string values are single bytes,
byteReplacer is now used, instead of the generic
algorithm.

This is just a new API to do many replacements at once.
While the point of this API is to be faster than doing replacements one
at a time, the implementation in this CL has the optimizations removed
and may actually be slower.
Future CLs will bring back & add optimizations.

Case-insensitive strcmp without using ToLower.
(Using ToLower is not always correct, and it allocates.)

Change the signature of Split to have no count,
assuming a full split, and rename the existing
Split with a count to SplitN.
Do the same to package bytes.
Add a gofix module.

This is a core API change.
1) gofix misc src
2) Manual adjustments to the following files under src/pkg:
gob/decode.go
rpc/client.go
os/error.go
io/io.go
bufio/bufio.go
http/request.go
websocket/client.go
as well as:
src/cmd/gofix/testdata/*.go.in (reverted)
test/fixedbugs/bug243.go
3) Implemented gofix patch (oserrorstring.go) and test case (oserrorstring_test.go)
Compiles and runs all tests.

Also some cleanup, removing redundant code. Make more
things use NewRequest. Add some tests, docs.

The need for a LastIndexAny function has come up in the discussion
for https://golang.org/cl/3008041/. This function is
implemented analogously to lastIndexFunc, using functions from
the utf8 package.

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.

strings.ToTitle converts all characters to title case, which for consistency with the
other To* functions it should continue to do. This CL adds string.Title, which
does a proper title-casing of the string.
A similar function for package bytes will follow once this is settled.
Fixes#933.

This is the Replace I suggested in the review of CL 1114041.
It's true that we already have
regexp.MustCompile(regexp.QuoteMeta(old)).ReplaceAll(s, new)
but because this Replace is doing a simpler job it is
simpler to call and inherently more efficient.
I will add the bytes implementation and tests to the
CL after the strings one has been reviewed.

parsing and printing to new syntax.
Use -oldparser to parse the old syntax,
use -oldprinter to print the old syntax.
2) Change default gofmt formatting settings
to use tabs for indentation only and to use
spaces for alignment. This will make the code
alignment insensitive to an editor's tabwidth.
Use -spaces=false to use tabs for alignment.
3) Manually changed src/exp/parser/parser_test.go
so that it doesn't try to parse the parser's
source files using the old syntax (they have
new syntax now).
4) gofmt -w src misc test/bench
4th set of files.
