/**
* Send a HTTP request to a URI.
*
* The body and headers are part of the arguments. The 'body' argument is for the body and will
* accept either a string or an array. The 'headers' argument should be an array, but a string
* is acceptable. If the 'body' argument is an array, then it will automatically be escaped
* using http_build_query().
*
* The only URI that are supported in the HTTP Transport implementation are the HTTP and HTTPS
* protocols. HTTP and HTTPS are assumed so the server might not know how to handle the send
* headers. Other protocols are unsupported and most likely will fail.
*
* The defaults are 'method', 'timeout', 'redirection', 'httpversion', 'blocking' and
* 'user-agent'.
*
* Accepted 'method' values are 'GET', 'POST', and 'HEAD', some transports technically allow
* others, but should not be assumed. The 'timeout' is used to sent how long the connection
* should stay open before failing when no response. 'redirection' is used to track how many
* redirects were taken and used to sent the amount for other transports, but not all transports
* accept setting that value.
*
* The 'httpversion' option is used to sent the HTTP version and accepted values are '1.0', and
* '1.1' and should be a string. Version 1.1 is not supported, because of chunk response. The
* 'user-agent' option is the user-agent and is used to replace the default user-agent, which is
* 'WordPress/WP_Version', where WP_Version is the value from $wp_version.
*
* 'blocking' is the default, which is used to tell the transport, whether it should halt PHP
* while it performs the request or continue regardless. Actually, that isn't entirely correct.
* Blocking mode really just means whether the fread should just pull what it can whenever it
* gets bytes or if it should wait until it has enough in the buffer to read or finishes reading
* the entire content. It doesn't actually always mean that PHP will continue going after making
* the request.
*
* @access public
* @since 2.7.0
* @todo Refactor this code. The code in this method extends the scope of its original purpose
* and should be refactored to allow for cleaner abstraction and reduce duplication of the
* code. One suggestion is to create a class specifically for the arguments, however
* preliminary refactoring to this affect has affect more than just the scope of the
* arguments. Something to ponder at least.
*
* @param string $url URI resource.
* @param str|array $args Optional. Override the defaults.
