[Qemu-block] [RFC PATCH 17/56] migration: Make MigrationStats sizes unsigned in QAPI/QMP

[Markus Armbruster]

Sizes should use QAPI type 'size' (uint64_t).  MigrationStats members
@transferred, @remaining, @total, @normal-bytes, @page-size are 'int'
(int64_t).  populate_ram_info(), populate_disk_info() and and many
places that update them in global variable @ram_counters implicitly
convert from unsigned types.

Change these MigrationStats members to 'size'.

query-migrate now reports them correctly above 2^63-1 instead of their
(negative) two's complement.

HMP's "info migrate" already reported them correctly, because it
printed the signed integer with PRIu64.
