If a thread asks to stop the miner, m_stop will be set, and
that thread will wait to join. If the main thread is exiting
at that time, it will ask the miner to stop, but the miner
will claim it's not mining and early out since m_stop is
set. This will cause the database and other things to get
shutdown. If the miner happens to find a block at that time,
it will try to call core, and crash.
Instead, lock and check whether any threads are currently
in m_threads, since they'll only be cleared once the threads
are joined. Moreover, since we lock, the second thread will
have to wait for the first one to have finished. Calling
join twice on a thread seems fine as per pthread_join(3).
This avoids the annoying case where the shell prints its prompt
after the last line from Monero output, causing line editing to
sometimes go wonky, for lack of a better term
It's better to just ignore them, the user does not really need
to know they're here. If the mask is wrong, they'll fail to be
used, and sweeping will fail as it tries to use it.

- return the right output data when offset is not zero
- do not consider import failed if result height is zero
(it can be 0 if unknown)
- select the right tx pubkey when using subaddresses (it's faster,
and we might select the wrong one if we got an output using one
of the additional tx keys)
- account for skipped outputs for spent/unspent balance info
"spent" is arguably wrong, since it will count spent change
multiple times as it goes through receive/spend cycles.
RPC connections now have optional tranparent SSL.
An optional private key and certificate file can be passed,
using the --{rpc,daemon}-ssl-private-key and
--{rpc,daemon}-ssl-certificate options. Those have as
argument a path to a PEM format private private key and
certificate, respectively.
If not given, a temporary self signed certificate will be used.
SSL can be enabled or disabled using --{rpc}-ssl, which
accepts autodetect (default), disabled or enabled.
Access can be restricted to particular certificates using the
--rpc-ssl-allowed-certificates, which takes a list of
paths to PEM encoded certificates. This can allow a wallet to
connect to only the daemon they think they're connected to,
by forcing SSL and listing the paths to the known good
certificates.
To generate long term certificates:
openssl genrsa -out /tmp/KEY 4096
openssl req -new -key /tmp/KEY -out /tmp/REQ
openssl x509 -req -days 999999 -sha256 -in /tmp/REQ -signkey /tmp/KEY -out /tmp/CERT
/tmp/KEY is the private key, and /tmp/CERT is the certificate,
both in PEM format. /tmp/REQ can be removed. Adjust the last
command to set expiration date, etc, as needed. It doesn't
make a whole lot of sense for monero anyway, since most servers
will run with one time temporary self signed certificates anyway.
SSL support is transparent, so all communication is done on the
existing ports, with SSL autodetection. This means you can start
using an SSL daemon now, but you should not enforce SSL yet or
nothing will talk to you.
