Changes in this CL:
1. 'exports' attribute renamed to roots
2. Removed restrictions for exporting a rule in a different repository
3. Kept restrictions for rules in the same repository but not in the same
package or subpackages
4. To get around restrictions, instead of the exported_by tag, one can use the
cc_shared_library_permissions rule
5. Added exports_filter that will match libraries in the transitive closure of
a root. Anything matched by the exports_filter will also be exported.
Restrictions as in 4. still apply.

Any library should be exportable by any cc_shared_library target regardless of whether the cc_shared_library target is in the same package or a parent package as long as the library author gives permission.
The library author can now do this by writing tags=["exported_by=//foo,//baz"].

For now we will restrict allowed exports to the same package. At the same time
static_deps should be used to take into account what should be linked into a
shared library.
