[PATCH libnbd 0/2] generator: Preparatory changes to the generator.
These are some simplifications to the generator. They don't probably
make much sense on their own, but they are preparatory to better
handling of enums, and or'd lists of flags.

[PATCH libnbd v2 0/5] lib: Implement closure lifetimes.
v1 was here:
https://www.redhat.com/archives/libguestfs/2019-July/thread.html#00231
The changes address everything that Eric picked up in his review of
the first two patches. I have also added two more patches (4 and 5)
which respectively fix docs and change int status -> unsigned status,
as discussed.
Passes make, check, check-valgrind.
