FS#6357, patch 1: let iramcopy and bss share the same space in codecs and

Browse source 
plugins. Currently, in case of plugins using IRAM bss is cleared twice,
once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only
during codec initialization. Also, removed double variables in codecs
storing a pointer to codec_api.
