information. This shouldn't normally be needed/used, but it's
occasionally helpful for writing code that passes toolstash -cmp.

The net/http/internal package contains a PEM-encoded private key used in
tests. This key is initialized at init time, which prevents it from
being stripped by the linker in non-test binaries.
Move the certificate and key to a new net/http/internal/testcert
package to ensure it is only included in binaries that reference it.

In 1.17, //go:build lines are fully supported. This entails changes to
the go command, vet, and gofmt. Document all of them.
I'm not Russ, but this is a significant change, it slipped under the
radar, and we're trying to get the release out. So here's what I got.
I wasn't sure where to put the go command change. On the one hand,
it's pretty significant. On the other, it certainly affects fewer
people than lazy loading. So it probably shouldn't be first, but I also
didn't want to bury it the middle of all the other module changes. Open

The compiler machinery that generates "map.zero" symbols marks them as
RODATA and DUPOK, which is problematic when a given application has
multiple map zero symbols (from different packages) with varying
sizes: the dupok path in the loader assumes that if two symbols have
the same name, it is safe to pick any of the versions. In the case of
map.zero, the link needs to select the largest symbol, not an
arbitrary sym.
To fix this problem, mark map.zero symbols as content-addressable,
since the loader's content addressability processing path already
supports selection of the larger symbol in cases where there are dups.

markInlBody/markObject/markType don't fully work as they stand for
generic functions/methods, since markInlBody can't understand method
calls on generic types. Those method calls will be resolved to concrete
methods in a full instantiation, but markInlBody on a generic
function/method can't understand those method calls. So, we won't
necessarily cause export of the appropriate extra method/function bodies
needed for inlining in an instantiated function.
One way to do this is just to make sure that we call markType
on all generic types that are exported (whether explicitly exported via
a capitalized name or unexported types that are referenced by a generic
function body). That way, we will call markInlBody on all possible
generic methods that might be called.
