Exported headers shouldn't be included as "foo.h" by code from the same module, it should only do so for module-internal headers. This is because the symlinking of exported headers (from include/openssl/foo.h to crypto/foo/foo.h) is being removed, and the exported headers are being moved to the include/openssl/ directory instead.
