This converts the project to allow btcd to be used with the glide
package manager in order to provide stable and reproducible builds
without the user having to jump through all of the hoops as they do
today.
It consists of adding a glide.yaml file which identifies the project
dependencies and locations along with a glide.lock file which contains
the complete dependency tree pinned to specific versions. Glide uses
these files to download the packages (or updates) to a local vendor
directory and checkout the correct pinned versions. The go tool, in
turn, is used to build/install btcd and will use the pinned versions in
the vendor directory.
This also updates TravisCI to build using glide, removes some of the
exceptions in the lint checks which are no longer required, and updates
the README.md with the new instructions needed to build the project with
glide.
Also, update TravisCI goclean script to remove the special casing which
ignored 'Id' from the lint output since that exception is no longer
needed. It was previously required due to the old version of btcjson,
but that is no longer in the repo.
This commit causes TravisCI to run several tools on each pull request and
commit to help ensure the code quality remains high. This includes gofmt,
goimports, golint, go vet, the race detector, and coverage stats.
Also, it instructs TravisCI to use nicer container-based builds.
