Use wp_remote_retrieve_* functions where appropriate

[aaroncampbell]

There are quite a few places where we're not using these:

• wp_remote_retrieve_headers()
• wp_remote_retrieve_header()
• wp_remote_retrieve_response_code()
• wp_remote_retrieve_response_message()
• wp_remote_retrieve_body().

Also removes useless $raw_response var

Old habits die hard? It looks like there are other places in core where this should be done as well:

• wp-admin/includes/plugin-install.php
• wp-admin/includes/theme.php
• wp-include/class-feed.php
• wp-include/class-wp-http-ixr-client.php
• wp-include/comment.php
• wp-include/functions.php
• wp-include/rss.php
• wp-include/update.php

I'll just expand this ticket and make a new patch.

I can't guarantee I caught them all, but that's all that I saw.

In [17928]:

Use wp_remote_retrieve_* helper functions instead of the raw HTTP response array. props aaroncampbell, fixes #17416.
