Draft: libvlc: return the amount of buffer read in size_t in imem callback
This is a more logical way to do. It may also work if we change the Read API of access modules to allow symmetrical types between requested and returned types.
Maybe we need to change the libvlc_media_new_callbacks()
name as well to signal an API change.
Alternative solution of !1507 (closed)
