* build: use golangci-lint This changes build/ci.go to download and run golangci-lint instead of gometalinter. * core/state: fix unnecessary conversion * p2p/simulations: fix lock copying (found by go vet) * signer/core: fix unnecessary conversions * crypto/ecies: remove unused function cmpPublic * core/rawdb: remove unused function print * core/state: remove unused function xTestFuzzCutter * core/vm: disable TestWriteExpectedValues in a different way * core/forkid: remove unused function checksum * les: remove unused type proofsData * cmd/utils: remove unused functions prefixedNames, prefixFor * crypto/bn256: run goimports * p2p/nat: fix goimports lint issue * cmd/clef: avoid using unkeyed struct fields * les: cancel context in testRequest * rlp: delete unreachable code * core: gofmt * internal/build: simplify DownloadFile for Go 1.11 compatibility * build: remove go test --short flag * .travis.yml: disable build cache * whisper/whisperv6: fix ineffectual assignment in TestWhisperIdentityManagement * .golangci.yml: enable goconst and ineffassign linters * build: print message when there are no lint issues * internal/build: refactor download a bit
