This prevents us from calling
allowed_anonymous_connection_compression_method() on the unused
guessed method (if any), and rejecting something that was already
safe to use.
Rationale: When use a guessed compression method, we already gave a
PROTOCOL_WARN when our guess differed from the declared method,
AND we gave a PROTOCOL_WARN when the declared method failed. It is
not a protocol problem that the guessed method failed too; it's just
a recovery attempt that failed.
A cached_dir_t object (for now) is always compressed with
DEFLATE_METHOD, but in handle_get_status_vote() to we were using the
general compression-negotiation code decide what compression to
claim we were using.
This was one of the reasons behind 22502.
Fixes bug 22669; bugfix on 0.3.1.1-alpha
Move the HTTPProxy option to the deprecated list so for now it will only warn
users but feature is still in the code which will be removed in a future
stable version.

On an hidden service rendezvous circuit, a BEGIN_DIR could be sent
(maliciously) which would trigger a tor_assert() because
connection_edge_process_relay_cell() thought that the circuit is an
or_circuit_t but is an origin circuit in reality.

This fixes an assertion failure in relay_send_end_cell_from_edge_() when an
origin circuit and a cpath_layer = NULL were passed.
A service rendezvous circuit could do such a thing when a malformed BEGIN cell
is received but shouldn't in the first place because the service needs to send
an END cell on the circuit for which it can not do without a cpath_layer.

Apparently, the unit tests relied on being able to make ed->x509
link certs even when they hadn't set any server flags in the
options. So instead of making "client" mean "never generate an
ed->x509 cert", we'll have it mean "it's okay not to generate an
ed->x509 cert".
(Going with a minimal fix here, since this is supposed to be a
stable version.)
