commit: set whole manifest entries at once (node with its associated flags)
Add a new function manifest.set that sets whole manifest entries at once,
so the caller doesn't have to do two separate operations:
m[p] = n
m.set_flags(f)
becomes:
m.set(p, n, f)
This obviously saves an extra lookup by path, and it also lets the
underlying manifest implementation to be more efficient as
it doesn't have to deal with partially-specified entries.
It makes the interaction conceptually simpler, as well, since we don't
have to go through an intermediate state of incorrect
partially-written entry.
(the real motivation for this change is an alternative manifest
implementation where we batch pending writes, and dealing with
fully defined entries makes the batching logic muchsimpler while
avoiding slowdown due to alternating writes and reads)
