windowed post generation now returns faulty sectors

Depends on:

• windowed post generation now returns faulty sectors specs-storage#12
• feat: return faulty sectors filecoin-ffi#134

[Stebalien]

We'll need to fix Sealer.pubSectorToPriv in ffiwrapper/verifier_cgo.go to actually do this. Instead of simply skipping missing sectors, it needs to replace them with the first non-missing sector.

[magik6k]

We don't pass this bitfield straight to the submitPost message - we retry the whole thing (with the loop at L342), assembling the set of sectors from scratch. This bitfield is only used to subtract sectors we couldn't prove in the previous try (L358)

pls give this issue more gas... we need it to be merged ASAP.

Does this solution solve the problem “sanity check err” ?

@whyrusleeping @magik6k A new problem has arisen
I update the latest master, Log shows are done many times computing window PoSt and generate window PoSt skipped sectors, Resulting in timeout

[kwuaint]

@FIRST "computing window PoSt" then "generate window PoSt skipped sectors", and do "computing window PoSt" and "generate window PoSt skipped sectors" again...

consume a lot of time.

It there's 10 or 50 sectors, it's OK. But there's 2349 sectors in one deadline, so the procedure can finished in half hour. It cause timeout and no SubmitWindowedPoSt, and winpost fail, the 2349 sectors turn to faults totally.
I think the root cause(faulty sectors #3710, #3710) found ,but we should rewrite the code.
