#16 Improve const-correctness

[Markus Elfring]

Would you like to apply the advices from the article "http://en.wikipedia.org/wiki/Const_correctness" to more places in your sources?
I suggest to add the key word "const" to the type specifiers for parameters like the following.
- http://sipp.svn.sourceforge.net/viewvc/sipp/sipp/trunk/auth.c?revision=154&view=markup
base64, hexa (global "variables")
user, password, method, uri, msgbody, auth, algo (function "createAuthHeaderMD5")
http://cvs.sourceforge.net/viewcvs.py/sox/sox/src/FFT.h?rev=1.1&view=markup

- http://sipp.svn.sourceforge.net/viewvc/sipp/sipp/trunk/rijndael.c?revision=27&view=markup
ft_tab, fl_tab (global "variables")

Hi Markus, as many other Open Source projects, SIPp is contribution driven. I will be very happy to receive a patch from you that implements this and check it in after review. Thanks a lot.

Would you like to provide a clear distinction between input and output parameters as an easy documentation aid?
