[SR-Users] force_send_socket

[Alex Balashov]

OK, I touched off a controversy with my use of the word "deprecated"
that I did not intend, as the implied intellectual or policy commitment
to that word is not really strong. :-) 

What I meant through that particular choice of words is that there is,
among those with some lengthy experience with the OpenSER pedigree, a
recognised set of core functions and ancient modules which correspond to
a different era of SER/OpenSER, and are not complementary to the ways of
doing things that are concomitant with the present generation of the
system. 

Examples from modules include most of the `avpops` module functions, as
well as the `usr_preferences` table - both take us back to a time before
generic SQL queries and arbitrary data sources were a first-class aspect
of Kamailio, as with the `sqlops` module, `htable`, etc. 

In the core, there are lots of functions such as strip(), prefix(),
rewritehostport(), and, in my view, force_send_socket(). These functions
don't take PV arguments, and are superceded by the more flexible direct
manipulation of the RURI, the destination set, and $fs, along with the
wealth of transformations available nowadays, which can be chained.

Not everyone shares this exact set of tacit assumptions, I imagine, and
I think that's what got folk exercised when I said "deprecated". These
functions will surely remain for backward compatibility.
