[SPARK-10903][SPARKR] R - Simplify SQLContext method signatures and use a singleton
Eliminate the need to pass sqlContext to method since it is a singleton - and we don't want to support multiple contexts in a R session.
Changes are done in a back compat way with deprecation warning added. Method signature for S3 methods are added in a concise, clean approach such that in the next release the deprecated signature can be taken out easily/cleanly (just delete a few lines per method).
Custom method dispatch is implemented to allow for multiple JVM reference types that are all 'jobj' in R and to avoid having to add 30 new exports.

Closes #9192 from felixcheung/rsqlcontext.
