* Removed LLCurlRequest and replaced it's last usage with LLHTTPClient API calls.
* Deleted dead code.
* Renamed all the get4/post4/put4/getByteRange4 etc, back to their
original name without the '4'.
Since curl 7.21.2 - (October 13 2010), curl_escape (a deprecated
function that will be removed in the future) changed it's behavior
and no longer escapes the characters '-', '.', '_' and '~'.
The only reasonable solution for us is to stop using it and
use our own version that mimics the old behavior. The only
other alternative would be to rename every .xml file with
escaped characters in their name upon installation, depending
on the behavior of the installed libcurl (on standalone anyway).
However, if you add to that in the future curl_escape has to
be replaced with curl_easy_escape, which is far from easy to
call as it requires a CURL to be passed for which LL invented
a wrapper in libllmessage, but did hide that (Curl::Easy is
only defined in a .cpp file), then we're better of just using
our own function, which I named LLWeb::curlEscape.
Message Builder is removed entirely as per requested
Message Log was updated to be less dependent on the message builder for later removal
Version reporting was fixed - Missed some tidbits from Inertia removal
