b03553737c Separate the flags for logging use bias. 
I think we want both sets of messages to appear independently to help us know
what needs tuning.

266419d244 Tolerate curve25519 backends where the high bit of the pk isn't ignored 
Right now, all our curve25519 backends ignore the high bit of the
public key. But possibly, others could treat the high bit of the
public key as encoding out-of-bounds values, or as something to be
preserved. This could be used to distinguish clients with different
backends, at the cost of killing a circuit.

As a workaround, let's just clear the high bit of each public key
indiscriminately before we use it. Fix for bug 8121, reported by
rransom. Bugfix on 0.2.4.8-alpha.

2e9cd4b724 Quick fix on 5956 for authorities 
Authorities don't set is_possible_guard on node_t, so they were
never deciding that they could build enough paths.  This is a quick
and dirty fix.

Bug not in any released version of Tor

b64dc35b5c Reinstate some fixes/tweaks from 6e4a4002 
These seem to have gotten conflicted out of existence while mike was
working on path bias stuff.

Thanks to sysrqb for collecting these in a handy patch.

7cde094fd5 Fix a warning when building with --disable-curve25519 
It appears that the code for 7291 gave an unused-value warning when
built with --disable-curve25519.

5ea9a90d68 Fix compilation with --disable-curve25519 option 
The fix is to move the two functions to format/parse base64
curve25519 public keys into a new "crypto_format.c" file.  I could
have put them in crypto.c, but that's a big file worth splitting
anyway.

Fixes bug 8153; bugfix on 0.2.4.8-alpha where I did the fix for 7869.

4eff8b6530 When we mark a node as a sybil, mark it down and reset its uptime to 0 
This prevents bug 8147, where such nodes would accrue points towards
Guard, Fast, HSDir, and so on.

b442930789 Fix serious breakage in connection_handle_write_impl 
When we first implemented TLS, we assumed in conneciton_handle_write
that a TOR_TLS_WANT_WRITE from flush_buf_tls meant that nothing had
been written. But when we moved our buffers to a ring buffer
implementation back in 0.1.0.5-rc (!), we broke that invariant: it's
possible that some bytes have been written but nothing.

That's bad.  It means that if we do a sequence of TLS writes that ends
with a WANTWRITE, we don't notice that we flushed any bytes, and we
don't (I think) decrement buckets.

Fixes bug 7708; bugfix on 0.1.0.5-rc
