RFR: 8087112 HTTP API and HTTP/1.1 implementation

[Michael McMahon]

Hi,

The following webrevs are for the initial implementation of JEP 110.
Most of it is in the jdk repository with some build configuration in the top
level repo for putting this code in its own module (java.httpclient).

The HTTP/2 implementation will come later.

Thanks,
Michael.
