Summary: /dev/urandom doesn't exist on FreeBSD

Initial Comment:
/dev/random is non-blocking on FreeBSD, like /dev/urandom on Linux. I changed to /dev/random, recompiled and things worked fine. 

Before:
an 20 20:43:54 sippan kamailio: WARNING:core:main: could not open /dev/urandom (2)
Jan 20 20:43:54 sippan kamailio: WARNING:core:main: using a unsafe seed for the pseudo random number generator

A good article here:
http://en.wikipedia.org/wiki/Urandom

Maybe the name should be depending on operating system. Seems like /dev/random is safe on FreeBSD, depending on how many bytes we read.

Hi Olle,

a easy solution would be to use some #define to differ between linux and
freebsd. Do you know the correct define for this OS?
