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.

In plugins and every program that opens a plugin, include a hash of
every imported package.
There are two versions of each hash: one local and one exported.
As the program starts and plugins are loaded, the first exported
symbol for each package becomes the canonical version.
Any subsequent plugin's local package hash symbol has to match the
canonical version.

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.

Until a few weeks ago, bionic, the Andoid libc, incorrectly
returned const char* (instead of char*) from dlerror(3).
