Feature Proposal: Remove the homegrown Foswiki::Net code that

Motivation

As pointed out in Item14023, our homegrown code is quite fragile, and doesn't handle the https:// implementation of the extensions repository. There really is no reason to maintain this when LWP is pretty much universally available.

The limitations of the fallback implementation are significant:

1. can only really be trusted for HTTP/1.0 urls. If HTTP/1.1 or another protocol is required, you are strongly recommended to require LWP.
2. Will not parse multipart content
3. Will not process redirects (configure relies on this)

Description and Documentation

• Remove the fallback implementation in Foswiki::Net::getExternalResource
• Remove lib/Foswiki/Net/HTTPResponse.pm from the MANIFEST
• Change LWP and LWP::Protocol::https to "required" dependencies
• Remove the unit tests for the fallback implementation.

Impact

No loss of functionality in Foswiki, and a more robust implemetation for support of external resources.
