www/{pecl|php}-http: Convert port
ext-http extension aims to provide a convenient and powerful set of
functionality for one of PHPs major applications. It eases handling of
HTTP URLs, dates, redirects, headers and messages, provides means for
negotiation of clients preferred language and charset, as well as a
convenient way to send any arbitrary data with caching and resuming
capabilities. It provides powerful request functionality too.
Please note that pecl infrastructure is being deprecated so create a
different port which is not dependent on pecl infrastructure.
This commit also removes pecl-http ports in lieu of this port.
