[Users] avpops updates

Hello, the avpops module was refurbished to benefit better of pseudo-variables. In addition, the avp and hdr pseudo-variables can have dynamic names. Here are some details: - all parameters being avp names in avpops functions MUST be specified in the same format as pseudo-variables: - $avp(i:23) - refers to the avp having the integer id 23 - $avp(s:test) - refers to the avp having the name 'test' - $avp($aliasid) - refers to the avp defined by avp alias 'aliasid' - example: avp_write("i:10", "$avp(i:30)") - write integer value 10 into the avp having the id 30 - avps and hdrs pseudo-variables can have dynamic names: -$avp($pvar) refers to the avp having the name the value of $pvar -$hdr($pvar) refers to the hdr having the name the value of $pvar - please note that the pseudo-variables specifiers have priority over avp aliases (if you define an avp alias $ru, $avp(ru) will refer to the avp having the name the value of R-URI) - in all parameters of avpops module can be used pseudo-variables where are expected values - avp_check("$fd", "eq/$td") returns true if the domain of From uri is the same with domain part of To uri - avp_write("$tU", "$avp($fU)") - writes the username in To header in the avp having the name the username from From header - avp_pushto() - cannot add anymore headers - same functionality is provided by the textops module via append_hf() and append_to_reply() functions - the format of the first parameter of avp_pushto() follows the pseudo-variables names as well. - avp_pushto("$ru[/username|domain]", "...") to rewrite parts of R-URI - avp_pushto("$du", "...") to rewrite dst_uri - for developers, internal structure int_str has changed from (int, str*) to (int,str) to avoid extra reference - the documentation will be updated soon (module readme and avpops tutorial) Still to come: - support for global avps: avps shared between all processes during the openser lifetime - support for script avps: avps specific per process with life time only during the script execution (temporary avps, which do not need to last too much, using private memory) - support for local avps: avps specific per process kept during openser lifetime (avps which need to be kept for each process, without synchronized access, using private memory) - avp_db_query() - ability to send a raw query (simple, joins, unions ...) to database and load the result in avps (e.g., avp_db_query("select first_name, last_name from subscriber where username='$tU' and domain='$td'", "$avp(first_name);$avp(last_name)")) Testing and feedback are more than welcome.
