Tomasz Malesinski 80da8b141c FS#6357, patch 1: let iramcopy and bss share the same space in codecs and
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.
