[reSIProcate] librecon: calling loadAllDynCodecs

[Daniel Pocock]

I notice a recent commit removed the call to loadAllDynCodecs

It seems this really is needed on Linux, I'll put it back with some comments

Below is an example of what happens when it is invoked with directory =
NULL and filter = ""

I'm not sure if the sipX problem is in the default filter string or in
the way the comparisons are being made.  The regex looks correct in
MpCodecFactory.h:
#  define CODEC_PLUGINS_FILTER "^codec_.*\\.so$"


pCodecFactory->loadAllDynCodecs(NULL, "");

ConversationManager.cxx:104 | No statically linked codecs or no codecs
found with default filter, trying without a filter

SipXHelper.cxx:41 | SIPxua:Anon:3FFFF44F5010:
MpCodecFactory::loadAllDynCodecs("/usr/lib/powerpc64le-linux-gnu/sipxtapi/codecs",
"")

SIPxua:Anon:3FFFF44F5010:
MpCodecFactory::loadDynCodec("/usr/lib/powerpc64le-linux-gnu/sipxtapi/codecs/codec_l16.so")
