[Qemu-devel] [PATCH 10/17] migration/qemu-file: add qemu_put_counted_string()

2017-02-13 Thread Vladimir Sementsov-Ogievskiy 
Add function opposite to qemu_get_counted_string.
qemu_put_counted_string puts one-byte length of the string (string
should not be longer than 255 characters), and then it puts the string,
without last zero byte.
