Juan Quintela 1bfe5f0586 migration: Move check_migratable() into qdev.c
The function is only used once, and nothing else in migration knows
about objects.  Create the function vmstate_device_is_migratable() in
savem.c that really do the bit that is related with migration.

Ashijeet Acharya 7562f90707 migrate: Introduce a 'dc->vmsd' check to avoid segfault for --only-migratable
Commit a3a3d8c7 introduced a segfault bug while checking for
'dc->vmsd->unmigratable' which caused QEMU to crash when trying to add
devices which do no set their 'dc->vmsd' yet while initialization.
Place a 'dc->vmsd' check prior to it so that we do not segfault for
such devices.

NOTE: This doesn't compromise the functioning of --only-migratable
option as all the unmigratable devices do set their 'dc->vmsd'.

Introduce a new function check_migratable() and move the
only_migratable check inside it, also use stubs to avoid user-mode qemu
build failures.

Paolo Bonzini 24b9462544 tests: cleanup ptimer-test
1) ptimer-test is not a qtest---it runs the ptimer.c code directly in the
ptimer-test process

2) ptimer-test has its own stubs file, so there is no need to add more
stubs to stubs/vmstate.c

device models as well as by the QEMU core. Add QTests for the ptimer.
