David Crawshaw 3f5c1adeb8 plugin: document support for macOS
All plugins issues I would call bugs now closed, so
(with some amount of optimism) update the plugin documentation.

David Crawshaw d8ae2156fe runtime, plugin: error not throw on duplicate open
Along the way, track bad modules. Make sure they don't end up on
the active modules list, and aren't accidentally reprocessed as
new plugins.

Fixes #19004

Francesc Campoy 38b3661b45 plugin: remove unnecessary import "C" from example
It seems that it is not needed to import the pseudo package "C"
for the plugin to be built correctly.
Removing it to avoid confusion.

David Crawshaw c1ada22bc1 cmd/go, plugin: disable plugins on darwin
We are seeing a bad stack map in #18190. In a copystack, it is
mistaking a slot for a pointer.

Presumably this is caused either by our fledgling dynlink support on
darwin, or a consequence of having two copies of the runtime in the
process. But I have been unable to work out which in the 1.8 window,
so pushing darwin support to 1.9 or later.

David Crawshaw 9da7058466 cmd/link, plugin: use full plugin path for symbols
Plumb the import path of a plugin package through to the linker, and
use it as the prefix on the exported symbol names.

Before this we used the basename of the plugin file as the prefix,
which could conflict and result in multiple loaded plugins sharing
symbols that are distinct.
