* bump golang.org/x/tools to HEAD * fix: adapt linters to the new validation system.
Run all linters per package. It allows unloading package data when it's processed. It dramatically reduces memory (and CPU because of GC) usage. Relates: #337
This commit adds full support for bodyclose linter (https://github.com/timakin/bodyclose), which checks if an `http.Body` element is correctly closed after usage. Since it can be used via `go/analysis', I followed the `govet' example as suggested by https://github.com/golangci/golangci-lint/wiki/How-to-add-a-custom-linter. This commit is fully tested, and contains a (flawed) test program which calls `http.Get()' on `https://google.com' and does not closes its corresponding `http.Body'.
