As far as I can tell there is no single entry-point into C++ code on Android.
Instead, GeckoThread and GeckoLibLoader call various functions to load libraries one-by-one.
We want to capture all that library loading in the profiler, so we need to kick off the base profiler at the beginning of whichever function is called first.

When Android shuts down the ndk process, it doesn't call the registered
atexit() handlers, which is normally where the profile data gets written
to file. Since the PGO test suite closes the browser when it is
finished, the nativeRun routine can manually call out to
__llvm_profile_dump() before returning.
This method has a downside that only the profile data from the calling
library gets written out, rather than for the whole process. Since we
are most interested in optimizing libxul, a new hook is added in
Bootstrap to make sure we get the profile data for the right library.

Adding or removing an FD from this API currently requires changes in about a
half dozen places. Ignoring the Java side of things. This patch changes the
API to pass a struct, rather than additional arguments for each FD, so that
adding and removing FDs only requires changing one declaration, and the two
call sites that add and consume the FDs.

This patch replaces the large -intPrefs/-boolPrefs/-stringPrefs flags with
a short-lived, anonymous, shared memory segment that is used to pass the early
prefs.
Removing the bloat from the command line is nice, but more important is the
fact that this will let us pass more prefs at content process start-up, which
will allow us to remove the early/late prefs split (bug 1436911).
Although this mechanism is only used for prefs, it's conceivable that it could
be used for other data that must be received very early by children, and for
which the command line isn't ideal.
Notable details:
- Much of the patch deals with the various platform-specific ways of passing
handles/fds to children.
- Linux and Mac: we use a fixed fd (8) in combination with the new
GeckoChildProcessHost::AddFdToRemap() function (which ensures the child
won't close the fd).
- Android: like Linux and Mac, but the handles get passed via "parcels" and
we use the new SetPrefsFd() function instead of the fixed fd.
- Windows: there is no need to duplicate the handle because Windows handles
are system-wide. But we do use the new
GeckoChildProcessHost::AddHandleToShare() function to add it to the list of
inheritable handles. We also ensure that list is processed on all paths
(MOZ_SANDBOX with sandbox, MOZ_SANDBOX without sandbox, non-MOZ_SANDBOX) so
that the handles are marked as inheritable. The handle is passed via the
-prefsHandle flag.
The -prefsLen flag is used on all platforms to indicate the size of the
shared memory segment.
- The patch also moves the serialization/deserialization of the prefs in/out of
the shared memory into libpref, which is a better spot for it. (This means
Preferences::MustSendToContentProcesses() can be removed.)

Bug 1343075 - 1a. Add TextEventDispatcherListener::GetIMEUpdatePreference; r=masayuki
Add a GetIMEUpdatePreference method to TextEventDispatcherListener to
optionally control which IME notifications are received by NotifyIME.
This patch also makes nsBaseWidget forward its GetIMEUpdatePreference
call to the widget's native TextEventDispatcherListener.
Bug 1343075 - 1b. Implement GetIMEUpdatePreference for all TextEventDispatcherListener; r=masayuki
This patch implements GetIMEUpdatePreference for all
TextEventDispatcherListener implementations, by moving previous
implementations of nsIWidget::GetIMEUpdatePreference.
Bug 1343075 - 2. Allow setting a PuppetWidget's native TextEventDispatcherListener; r=masayuki
In PuppetWidget, add getter and setter for the widget's native
TextEventDispatcherListener. This allows overriding of PuppetWidget's
default IME handling. For example, on Android, the PuppetWidget's native
TextEventDispatcherListener will communicate directly with Java IME code
in the main process.
Bug 1343075 - 3. Add AIDL interface for main process; r=rbarker
Add AIDL definition and implementation for an interface for the main
process that child processes can access.
Bug 1343075 - 4. Set Gecko thread JNIEnv for child process; r=snorp
Add a JNIEnv* parameter to XRE_SetAndroidChildFds, which is used to set
the Gecko thread JNIEnv for child processes. XRE_SetAndroidChildFds is
the only Android-specific entry point for child processes, so I think
it's the most logical place to initialize JNI.
Bug 1343075 - 5. Support multiple remote GeckoEditableChild; r=esawin
Support remote GeckoEditableChild instances that are created in the
content processes and connect to the parent process GeckoEditableParent
through binders.
Support having multiple GeckoEditableChild instances in GeckoEditable by
keeping track of which child is currently focused, and only allow
calls to/from the focused child by using access tokens.
Bug 1343075 - 6. Add method to get GeckoEditableParent instance; r=esawin
Add IProcessManager.getEditableParent, which a content process can call
to get the GeckoEditableParent instance that corresponds to a given
content process tab, from the main process.
Bug 1343075 - 7. Support GeckoEditableSupport in content processes; r=esawin
Support creating and running GeckoEditableSupport attached to a
PuppetWidget in content processes.
Because we don't know PuppetWidget's lifetime as well as nsWindow's,
when attached to PuppetWidget, we need to attach/detach our native
object on focus/blur, respectively.
Bug 1343075 - 8. Connect GeckoEditableSupport on PuppetWidget creation; r=esawin
Listen to the "tab-child-created" notification and attach our content
process GeckoEditableSupport to the new PuppetWidget.
Bug 1343075 - 9. Update auto-generated bindings; r=me
Use the GeckoService load-libs action to load and extract new libraries
when we receive the update broadcast. This makes us not block the UI
thread to extract libs, and lets Fennec run normally if the user
launches Fennec right after updating.
Here, we also modify APKOpen to use the XPCOM glue loading process
instead of custom symbol resolution, so that the Bootstrap API can be
used in a more straightforward manner.
