b2e9fdc00f test: expect that files may disappear from /proc/PID/fd/ (Vasil Dimov)
Pull request description:
`get_socket_inodes()` calls `os.listdir()` and then iterates on the results using `os.readlink()`. However a file may disappear from the directory after `os.listdir()` and before `os.readlink()` resulting in a `FileNotFoundError` exception.
It is expected that this may happen for `bitcoind` which is running and could open or close files or sockets at any time. Thus ignore the `FileNotFoundError` exception.

`p2p_seednode.py` would try to connect to `0.0.0.1` and `0.0.0.2` as
seed nodes. This sends outbound TCP packets on a non-loopback interface
to the default router.
Configure an unavailable proxy for all executions of `bitcoind` during
this test. Also change `0.0.0.1` and `0.0.0.2` because connecting to
them would skip the `-proxy=` setting because for such an address:
* `CNetAddr::IsLocal()` is true, thus
* `CNetAddr::IsRoutable()` is false, thus
* `CNetAddr::GetNetwork()` is `NET_UNROUTABLE`, even though
`CNetAddr::m_net` is `NET_IPV4`.
This speeds up the execution time of `p2p_seednode.py`
from 12.5s to 2.5s.
`get_socket_inodes()` calls `os.listdir()` and then iterates on the
results using `os.readlink()`. However a file may disappear from the
directory after `os.listdir()` and before `os.readlink()` resulting in a
`FileNotFoundError` exception.
It is expected that this may happen for `bitcoind` which is running and

`FileNotFoundError` exception.
If requested, make the SOCKS5 Python proxy redirect each connection to a
given destination. Actually act as a real proxy, connecting the
client to a destination, except that the destination is not what the
client asked for.
This would enable us to "connect" to Tor addresses from the functional
tests.
I added two new tests that will cover the nNew and nTried tests which
add coverage to the if block by checking values larger than our range
since we only check for negative values now

The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.
