The new tests in CL 28494 exposed a bug: the ObjC generator does
not avoid reserved names and names with special meaning ("init").
Generalize the name sanitizer from the Java generator and use that.
Also, move the lowerFirst function to gen.go since it is now used
by both generators.

There was a discussion a year ago about making methods and types
lowercase in ObjC (https://github.com/golang/go/issues/12889),
which was done (https://go-review.googlesource.com/#/c/15780/),
alas the suggested Java lower casing was never addressed.
This CL converts all generated Java methods to lower case.
