This modification is necessary for userfault fd features which are required to be requested from userspace. UFFD_FEATURE_THREAD_ID is a one of such "on demand" feature, which will be introduced in the next patch. QEMU have to use separate userfault file descriptor, due to userfault context has internal state, and after first call of ioctl UFFD_API it changes its state to UFFD_STATE_RUNNING (in case of success), but kernel while handling ioctl UFFD_API expects UFFD_STATE_WAIT_API. So only one ioctl with UFFD_API is possible per ufd.

That tiny refactoring is necessary to be able to set UFFD_FEATURE_THREAD_ID while requesting features, and then to create downtime context in case when kernel supports it.

Fill postcopy-able pending only if ram postcopy is enabled. It is necessary because of there will be other postcopy-able states and when ram postcopy is disabled, it should not spoil common postcopy related pending.

Now postcopy-able states are recognized by not NULL save_live_complete_postcopy handler. But when we have several different postcopy-able states, it is not convenient. Ram postcopy may be disabled, while some other postcopy enabled, in this case Ram state should behave as it is not postcopy-able. This patch add separate has_postcopy handler to specify behaviour of savevm state.

Provide helpers to convert bitmaps to little endian format. It can be used when we want to send one bitmap via network to some other hosts. One thing to mention is that, these helpers only solve the problem of endianess, but it does not solve the problem of different word size on machines (the bitmaps managing same count of bits may contains different size when malloced). So we need to take care of the size alignment issue on the callers for now.

The only prototype doesn't need anything from the lib header, and not including it here allows files that include this header, for example vl.c, to compile without the libseccomp cflags. The breakage is since c3883e1f for environments where `pkg-config --cflags libseccomp" is non-empty.
