Protocol string is set has const char in fko_protocol_t.
New tests for rc file processing (SPA_SOURCE_PORT, FW_TIMEOUT).

Added spa source port variable to dump_transmit_options() and renamed port
to destination port.
Removed duplicate variable in the test suite (fake_spoof_ip/spoof_ip).
First attempt to not ovewrite some configuration variables with --save-rc-stanza.

At this time it only does not overwrite the KEY and HMAC variable without asking the user
what he wants to do.
Continued implementing a way to not overwrite KEY.. variables with --save-rc-stanza
mrash/fwknop#67
Fixed names of function for better understanding.
Merge remote-tracking branch 'upstream/master'
Ask the user whether he wants to overwrite a variable in the updated rc file or not.
Added --force-stanza command line arg to avoid prompting the user.
Added GPG_SIGNER and GPG_RECIPIENT to the list of important variables.
Merge remote-tracking branch 'upstream/master'
Added force-stanza to the client documentation.
Fixed command line arguments (key-base64-rijndael and key-base64-hmac).

The cmd_opts structure containing the command line args does not follow the
documentation. This update fix it.
Replaced printf() by log_msg().
Added new tests to the test suite to validate the --save-rc-stanza command line argument.
Merge remote-tracking branch 'upstream/master'
minor typo fix
[server] added --pcap-any-direction along with config file support

From the config file comments:

This variable controls whether fwknopd is permitted to sniff SPA packets
regardless of whether they are received on the sniffing interface or sent
from the sniffing interface.  In the later case, this can be useful to have
fwknopd sniff SPA packets that are forwarded through a system and destined
for a different network.  If the sniffing interface is the egress interface
for such packets, then this variable will need to be set to "Y" in order for
fwknopd to see them.  The default is "N" so that fwknopd only looks for SPA
packets that are received on the sniffin
