This gives us the flexibility we need to also handle regular downloads
and uploads in gitlab-workhorse.

Accomodate broken HTTP clients

HTTP header lookups are supposed to be case-insensitive but some
clients do a case insensitive lookup, which breaks because of Go's
header canonicalization.

Pass LD_LIBRARY_PATH to the git command

As gitlab-shell does in https://gitlab.com/gitlab-org/gitlab-shell/blob/master/lib/gitlab_shell.rb#L126

LD_LIBRARY_PATH is needed when using Software Collections for instance but there are probably many other scenarios that need it as well. It was passed to git (and from git to hooks) by gitlab-shell, and still is for SSH access, but it was not the case anymore for HTTP access with the introduction of gitlab-git-http-server/git-workhorse.

"git archive" download support

See merge request !2
