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.
