3bc195659a pkg/vm: fix error handling in XDROP() 
Found by GolangCI:
  Error return value of ctx.Estack.Remove is not checked (from errcheck)
  nilness: impossible condition: nil != nil (from govet)

06f9e1d123 pkg/(crypto|vm): fix GolangCI errcheck warnings 
Like:
  Error return value of alg.Write is not checked (from errcheck)

Actually even though the hash.Hash implements an io.Writer interface (that
return meaningful things on .Write()) it has this comment in its
documentation:

// Write (via the embedded io.Writer interface) adds more data to the running hash.
// It never returns an error.

so it should be OK to ignore return results here.

depend on the Chain package.

[PeerMgr] Add Caching and Re-processing system (#263) 
[peermgr]

- Add request cache with tests
- Add requestCache to peermgr
- refactored peer manager tests
- Added blockInfo struct, to allow sorting on the blockIndex
- added helper methods for cache, pickItem, pickFirstItem, removeHash,
findHash and refactored tests
- renamed requestcache to blockcache
- refactored peer manager to use block cache for block requests *only*
- added blockCallPeer function to handle block requests only
- refactored onDisconnect to add back any pending peer requests that the
disconnected peer did not complete into the peer manager queue

[peermgr/server]

- Modify onBlock handler in server, to send peermgr a BlockInfo struct

[peermgr/syncmgr/server]

- Modified blockIndex in BlockInfo to be uint32 and not uint64
- RequestBlocks in syncmgr now takes an index along with the hash
- modified syncmgr code to pass index along with hash in all methods
