qemu-char: General chardev "memory" code cleanup
Inline trivial cirmem_chr_is_empty() into its only caller. Rename qemu_chr_cirmem_count() to cirmem_count(). Fast ring buffer index wraparound. Without this, there's no point in restricting size to a power two. qemu_is_chr(chr, "memory") returns *zero* when chr is a memory character device, which isn't what I'd expect. Replace it by the saner and more obviously correct chr_is_cirmem(). Also avoids encouraging testing for specific character devices elsewhere.
