back ports of #2008 and #2043 for 19.03

go1.12.8 (released 2019/08/13) includes security fixes to the net/http and net/url packages.
See the Go 1.12.8 milestone on our issue tracker for details:

https://github.com/golang/go/issues?q=milestone%3AGo1.12.8

  • net/http: Denial of Service vulnerabilities in the HTTP/2 implementation
    net/http and golang.org/x/net/http2 servers that accept direct connections from untrusted
    clients could be remotely made to allocate an unlimited amount of memory, until the program
    crashes. Servers will now close connections if the send queue accumulates too many control
    messages.
    The issues are CVE-2019-9512 and CVE-2019-9514, and Go issue golang.org/issue/33606.
    Thanks to Jonathan Looney from Netflix for discovering and reporting these issues.
    This is also fixed in version v0.0.0-20190813141303-74dc4d7220e7 of golang.org/x/net/http2.
    net/url: parsing validation issue
  • url.Parse would accept URLs with malformed hosts, such that the Host field could have arbitrary
    suffixes that would appear in neither Hostname() nor Port(), allowing authorization bypasses
    in certain applications. Note that URLs with invalid, not numeric ports will now return an error
    from url.Parse.
    The issue is CVE-2019-14809 and Go issue golang.org/issue/29098.
    Thanks to Julian Hector and Nikolai Krein from Cure53, and Adi Cohen (adico.me) for discovering
    and reporting this issue.

This allows overriding the version of Go without making modifications in the
source code, which can be useful to test against multiple versions.

For example:

    make GO_VERSION=1.13beta1 -f docker.Makefile binary

waiting for Golang-cross image to become available on Docker Hub docker/golang-cross#36

For now, just verifying that an error is returned, but not checking the
error message itself, because those are not under our control, and may
change with different Go versions.

```
