go-1.12-bp151.2.1

- bump the package only to 1.12 for distros where this actually
  builds

- go1.12 (released 2019/02/25) includes changes in the implementation of the
  toolchain, runtime, and libraries. As always, the release maintains the Go 1
  promise of compatibility. Upstream expects almost all Go programs to continue
  to compile and run as before.
  * GO111MODULE=on enables module-aware operations outside of a module directory
  * GODEBUG=tls13=1 enables opt-in support for TLS 1.3 in the crypto/tls package
    per RFC 8446. Will be default in go1.13.
  * trace tool now supports plotting mutator utilization curves, including
    cross-references to the execution trace. These are useful for analyzing the
    impact of the garbage collector on application latency and throughput.
  * arm64 assembler platform register renamed from R18 to R18_PLATFORM
  * improvements to gc
  * race detector is now supported on linux/arm64
  * cgo is now supported on linux/ppc64
  * go1.12 is the last release that will support binary-only packages.

- go1.11.5 (released 2019/01/23) security release fixes CVE-2019-6486 (bsc#1123013).
  * go#29903 crypto/elliptic: CPU DoS vulnerability affecting P-521 and P-384

- go1.11.4 (released 2018/12/14) includes fixes to cgo, the compiler, linker,
  runtime, documentation, go command, and the net/http and go/types packages.
  It includes a fix to a bug introduced in Go 1.11.3 that broke go get for
  import path patterns containing "...". See the Go 1.11.4 milestone on our
  issue tracker for details.

- Update to Go 1.11.3 (released 2018/12/13). This includes fixes to
  the crypto/x509 and cmd/go packages. See the Go 1.11.3 milestone
  on upstream tracker for details:
  https://github.com/golang/go/issues?q=milestone%3AGo1.11.3
  * bsc#1118897 CVE-2018-16873
    go#29230 cmd/go: remote command execution during "go get -u"
  * bsc#1118898 CVE-2018-16874
    go#29231 cmd/go: directory traversal in "go get" via curly braces in import paths
  * bsc#1118899 CVE-2018-16875
    go#29233 crypto/x509: CPU denial of service
  * Upstream is aware of a functionality regression in "go get" when
    executed in GOPATH mode on an import path pattern containing "..."
    (e.g., "go get github.com/golang/pkg/..."), when downloading
    packages not already present in the GOPATH workspace. This is go#29241
    and will be resolved in the next minor patch release go-1.11.4

- Revert golang(API) removal since it turns out this breaks >= requires in
  certain cases. Instead we recommend that folks set Prefer: go in all of their
  projects. boo#1114209

- Update to version 1.11.1:
  * includes fixes to the compiler, documentation, go command, runtime,
    and the crypto/x509, encoding/json, go/types, net, net/http and reflect
    packages.
- cmd/compile:
  * bad walkinrange rewrites on constant above 2**63
  * function compiled without bounds checking and -1 index access
  * missing bounds checks in 1.11
  * panic in cmd/compile/internal/gc.typecheck1
  * race detector detects race with close(chan) and len(chan)
- cmd/go:
  * 'go test -gcflags=all=-l' appears not to disable inlining
  * GOMIPS environment variable does not affect caching of mipsle code
  * TestScript/mod_install_versioned consistently failing on macOS High Sierra
  * build fails when setting linker to lld using ldflags
  * go list -json -compiled -test -e upspin.io/test fails with non-zero exit status
- doc:
  * GOFLAGS environment variable not in 1.11 release notes
  * downloads page claims that Go 1.11 supports unsupported operating systems Documentation
- encoding/json:
  * empty fields in json.UnmarshalTypeError
- go/types:
  * assertion failure setting up composite literal with incomplete element type
  * some facts are missing after an error
- net/http:
  * WASM Roundtripper crash when using "no-cors" mode
- net:
  * LookupTXT bug
  * empty DNS answers should fail fast
  * testSpliceReaderAtEOF closed connection: got err = splice: invalid argument
- reflect:
  * MethodByName().Interface() leads to fatal error: sweep increased allocation count
- runtime:
  * invalid pointer found on stack
  * timeouts in os/signal tests

- Fix stray 1.10 version reference preventing 1.11 only package solutions

- Update to version 1.11:
  * Most of its changes are in the implementation of the toolchain,
    runtime, and libraries. As always, the release maintains the
    Go 1 promise of compatibility. We expect almost all Go programs
    to continue to compile and run as before.
  * For more details check: https://golang.org/doc/go1.11
- Use gcc8 instead of gcc7 for Factory/Tumbleweed.
- Update compiler-rt TSAN binary: the precompiled versions of
  LLVM's compiler-rt has updated to commit
  fe2c72c59aa7f4afa45e3f65a5d16a374b6cce26 in go1.11 source.
- Remove patch:
  * fix-sanitizer-build-against-latest-glibc.patch: upstream fixed.
- Add patch:
  * gcc8-go.patch: use gcc8 instead of gcc7 for Factory/Tumbleweed.

- Remove golang(API) provides, since the go<ver> packages now provide this and
  providing it here causes issues when building under SLE12 (not to mention
  being confusing -- since golang(API) is used to pin versions). boo#1114209

- Update to version 1.10.4:
  * go1.10.4 (released 2018/08/24) includes fixes to the go command,
    linker, and the net/http, mime/multipart, ld/macho, bytes, and
    strings packages. See the Go 1.10.4 milestone on our issue
    tracker for details.

- Update to version1.10.3:
  * go1.10.3 (released 2018/06/05) includes fixes to the go command,
    and the crypto/tls, crypto/x509, and strings packages. In particular,
    it adds minimal support to the go command for the vgo transition.
    See the Go 1.10.3 milestone on our issue tracker for details.

- Update to version 1.10.2:
  * includes fixes to the compiler, linker, and go command.
- Changes in version 1.10.1:
  * includes fixes to the compiler, runtime, and the archive/zip,
    crypto/tls, crypto/x509, encoding/json, net, net/http, and net/http/pprof packages.
- Changes in version 1.10:
  * This release improves caching of built packages, adds caching of successful
    test results, runs vet automatically during tests, and permits passing string
    values directly between Go and C using cgo. A new compiler option whitelist may
    cause unexpected invalid flag errors in code that built successfully with older releases.

- Provide golang(API) = 1.9, so that this symbol can be required
  and provided, as preferred one, by the unversioned go package.
