soup_form_request_new_from_hash can return NULL, e.g. if the given url
is malformed.

Where the checked version is < 2.36, which we now require

Quote from wikipedia: "Fire Eagle has closed as of February 2013".

priv->session was a SoupSession since the last commit, which also
removed every practical usage or priv->session_sync.

So make check is less annoying.

An equivalent _parse_token_response exists that does not contain a typo.

steal_oauth_params() creates a list of strdup'ed strings containing the
name of the ouath parameters which should be stolen from the call
arguments. However, the code makes sure to free the list, but never
frees its content, causing a leak. This commit makes sure the dup'ed
strings are freed.

This prevents a crash due to cur_node being NULL.

It can be helpful when handling the "authenticate" signal to allow
to cancel the authentication instead of failing with an error.

Calling soup_server_run in a new thread, and calling
soup_server_get_port() on the same SoupServer instance
right after creating the thread.
With recent libsoup, this sometimes causes a crash when the 2 threads
try to call soup_server_ensure_listening() at the same time.
Moving the call to soup_server_get_port() before the thread creation
avoids this race condition.

These errors should only be shown if REST_DEBUG=xml-parser is set.
