The shims in the lazy libs bypass the stubs and hence the vetted
exported APIs in the .map.txt files. To avoid inadvertently giving
external access to internal APIs that way, let's apply the .map.txt
files as version scripts to the lazy libs instead, so that any
functions added there just don't become available to external code
unless the .map.txt files get updated.
This hack doesn't work if the lazy libs are linked statically, so
restrict them to be shared libs (although ideally they should be static
instead to avoid the shared lib overheads).
Also drop the shims for the two functions added in
https://r.android.com/2689969 and https://r.android.com/3022103,
because they're only used internally in ART and don't go through the
shims.

Add a function to native bridge that generates trampolines
for guest pointers and call it for native-bridged namespaces.

NativeBridge needs to know if JNI call is @CriticalNative, starting with
v7 getTrampoline2 is used in place of getTrampoline.

exported symbols.
The APEX stubs don't have any practical effect on the lazy loading
library wrappers. Add notes about that and update the function wrappers
to keep them in sync.
Also add tests for the lazy libraries. That necessitated some
reshuffling in libnativeloader tests to reuse the mocks.

It's required to clean-up the emulated enviroment (e.g. close file
descriptors) after emulated execution in doPreload() in app-zygote.
