/* NAME
/*	tls_proxy_print
/* SUMMARY
/*	write DSN structure to stream
/* SYNOPSIS
/*	#include <tls_proxy.h>
/*
/*	int     tls_proxy_context_print(print_fn, stream, flags, ptr)
/*	ATTR_PRINT_MASTER_FN print_fn;
/*	VSTREAM *stream;
/*	int     flags;
/*	void    *ptr;
/* DESCRIPTION
/*	tls_proxy_context_print() writes a TLS_SESS_STATE structure
/*	to the named stream using the specified attribute print
/*	routine. TLS_SESS_STATE() is meant to be passed as a call-back
/*	to attr_print(), thusly:
/*
/*	... SEND_ATTR_FUNC(tls_proxy_context_print, (void *) tls_context), ...
/* DIAGNOSTICS
/*	Fatal: out of memory.
