Cédric Le Goater	e1d4ea53d6	vfio: Introduce a new header file for external migration services The migration core subsystem makes use of the VFIO migration API to collect statistics on the number of bytes transferred. These services are declared in "hw/vfio/vfio-common.h" which also contains VFIO internal declarations. Move the migration declarations into a new header file "hw/vfio/vfio-migration.h" to reduce the exposure of VFIO internals. While at it, use a 'vfio_migration_' prefix for these services. To be noted, vfio_migration_add_bytes_transferred() is a VFIO migration internal service which we will be moved in the subsequent patches.

Avihai Horon	38c482b477	migration: Add migration prefix to functions in target.c The functions in target.c are not static, yet they don't have a proper migration prefix. Add such prefix.

Avihai Horon	808642a2f6	vfio/migration: Reset bytes_transferred properly Currently, VFIO bytes_transferred is not reset properly: 1. bytes_transferred is not reset after a VM snapshot (so a migration following a snapshot will report incorrect value). 2. bytes_transferred is a single counter for all VFIO devices, however upon migration failure it is reset multiple times, by each VFIO device. Fix it by introducing a new function vfio_reset_bytes_transferred() and calling it during migration and snapshot start. Remove existing bytes_transferred reset in VFIO migration state notifier, which is not needed anymore.

Thomas Huth	43bd0bf30f	migration: Move populate_vfio_info() into a separate file The CONFIG_VFIO switch only works in target specific code. Since migration/migration.c is common code, the #ifdef does not have the intended behavior here. Move the related code to a separate file now which gets compiled via specific_ss instead.
