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