If COMPRESS_OK occurs but data is neither consumed nor generated,
treat it as a BUG and a COMPRESS_ERROR.
This change is meant to prevent infinite loops in the case where
we've made a mistake in one of our compression backends.
Closes ticket 22672.
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
Many places in our code assume that uint8_t is the same type as
unsigned char. Test this assumption in the configure script. This is
important because of the privileged aliasing properties of character
types in C.
Fixes#22410.
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.
