Removing the exported symbols is straightforward enough.
The only wrinkle is that PeerConnectionCtx.cpp gets compiled with and
without MOZILLA_INTERNAL_API. When compiling without
MOZILLA_INTERNAL_API, mozilla::services::Get*Service was redirected to
the _external_* symbol variants. But as the _external_* symbols no
longer exist, PeerConnectionCtx.cpp's code no longer worked.
Fortunately, PeerConnectionCtx.cpp already contains a few #ifdef
MOZILLA_INTERNAL_API blocks to handle internal/external compilation;
fixing this newest issue was just a matter of extending existing blocks
and adding new ones. The key observation is that we never added any
observers when compiling without MOZILLA_INTERNAL_API, so we can #ifdef
out the removals of observers, as those would have no effect, and simply
skip getting the observer service for the observer additions if we're
compiling without MOZILLA_INTERNAL_API.
... except when building with clang on Linux because gyp doesn't seem to recognize the clang static analysis or ASan builds as clang, thus ignoring the following warning suppressions in signaling.gyp. We must suppress the following -Winconsistent-missing-override clang warnings from an upstream webrtc header file to be able to compile webrtc/signaling as warnings-as-errors:

WINVER=0x0601 implies PSAPI_VERSION=2. We should not mix PSAPI_VERSION.
