page_cache: dup memory on insert

The page cache frees all data on finish, on resize and
if there is collision on insert. So it should be the caches
responsibility to dup the data that is stored in the cache.

migration: merge qemu_popen_cmd with qemu_popen

There is no reason for outgoing exec migration to do popen manually

migration: move rate limiting to QEMUFile

Rate limiting is now simply a byte counter; client call
qemu_file_rate_limit() manually to determine if they have to exit.
So it is possible and simple to move the functionality to QEMUFile.

This makes the remaining functionality of s->file redundant;...
