Characters should be casted as unsigned before use in functions from
<ctype.h>. Otherwise the compiler treats 8-bit characters (eg UTF-8) as
negative values (since it expects signed integers) and they no longer
match the comparison tables. Worse, the character 0xff gets interpreted
as -1 (like EOF). In turn, it helps to explicitly cast the result as a
signed integer, since this is what is expected. Characters in the range
0x80-0xff do keep their original values.

and fwknopd_utests binaries.
When profil coverage is enbaled, lcov filee are parsed by test-fwknop.pl and added
to the main profil coverage report in the output directory.
Running make from the main directory build the c-unit test suites if enabled.
This commit updates all authorship and copyright information to include a
standard header that references the AUTHORS and CREDITS file. This standard
header was written by the Debian legal team at the request of Franck Joncourt.
This commit replaces the separately implemented client/server
is_base64() check with a single libfko function, and libfko itself now
uses it as well before prepending Rijndael or GnuPG base64 encoded
prefixes.
Lots of places in the code were already using {0} to initialize stack char
arrays, but memset() was being used as well. This commit removes all
unnecessary memset() calls against char arrays that are already initialized
via {0} (which sets all members to zero for such arrays).
Significant merge from Franck Joncourt to add the ability to save command line
args to ~/.fwknoprc stanzas. This merge is in support of #4.

[client+server] Applied patch from Franck Joncourt to remove unnecessary
chmod() call when creating client rc file and server replay cache file.
The permissions are now set appropriately via open(), and at the same
time this patch fixes a potential race condition since the previous code
used fopen() followed by chmod().
- [client+server] Fernando Arnaboldi from IOActive found that strict
filesystem permissions for various fwknop files are not verified. Added
warnings whenever permissions are not strict enough, and ensured that
files created by the fwknop client and server are only set to user
read/write.
- [client] Fernando Arnaboldi from IOActive found a local buffer overflow
in --last processing with a maliciously constructed ~/.fwknop.run file.
This has been fixed with proper validation of .fwknop.run arguments.
Added --key-gen to allow KEY_BASE64 and HMAC_KEY_BASE64 keys to be created from
reading random data from /dev/random. These keys can be placed within server
access.conf files and corresponding client .fwknoprc files for SPA
communications. The HMAC key is not used yet with this commit, but that is
coming.
