Consider a situation where the user passes "--status-fd 3" but file
descriptor 3 is not open.
During the course of executing the rest of the commands, it's possible
that gpg itself will open some files, and file descriptor 3 will get
allocated.
In this situation, the status information will be appended directly to
whatever file happens to have landed on fd 3 (the trustdb? the
keyring?).
This is a potential data destruction issue for all writable file
descriptor options:
--status-fd
--attribute-fd
--logger-fd
It's also a potential issue for readable file descriptor options, but
the risk is merely weird behavior, and not data corruption:
--override-session-key-fd
--passphrase-fd
--command-fd
Fixes this by checking whether the fd is valid early on before using
it.

This patch allows the user to modify the behavior of the
--faked-system-time option: by appending a '!' to the parameter,
time in GnuPG will be frozen at the specified time, instead of
advancing normally from that time onward.

When removing not a simple socket file but the entire directory the
old code missed most events and thus did not worked properly.
IN_DELETE_SELF has also been added to the watch list to detect a
removal of the directory. However, in all tests that event was not
triggered. The only way it could be triggered was by not watching
the socket dir but an arbitary directory and rmdir that.
