This removes the unnecessary setting of c-basic-offset from all
python-mode files.
This was automatically generated using
perl -pi -e 's/; *c-basic-offset: *[0-9]+//'
... on the affected files.
The bulk of these files are moz.build files but there a few others as
well.

Bluetooth availability depends on available driver; not the base system's
version. This patch separates both. Following other modules, it also moves
search-path setup for BT header files into the affected moz.build scripts.

The new helper |DBusConnectionDelete| deletes instances of |DBusConnection|
that are stored in a |UniquePtr|. It will close open connections before un-
ref'ing them.
For shared DBus connections, continue to use |RefPtr|.

The I/O helpers for DBus are based on |RawDBusConnection|'s |Send*| and
|Watch| methods. Moving them out of this class will make them available
to other modules.
The header files for DBus IPC forward declare several DBus types in
a way that interferes with the actual declarations. It's better to
include the DBus headers directly
The class template |ScopedFreePtrTrais| has been removed. This patch
updates |RawDBusConnection| to not refer to it any longer. Instead, the
provided helper method |empty| is implemented directly.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

The patch removes 455 occurrences of FAIL_ON_WARNINGS from moz.build files, and
adds 78 instances of ALLOW_COMPILER_WARNINGS. About half of those 78 are in
code we control and which should be removable with a little effort.

This patch removes the constant BLUEZ_DBUS_BASE_IFC from the file
RawDBusconnection.cpp. The constant is specific to BlueZ, and that's
where it's located now.
DBusWatcher is a helper for RawDBusConnection. This patch moves
both classes into the same file. Calling RawDBusConnection::Watch
installs a DBusWatcher for the connection.
This patch removes the internal tasks from the implementation of
RawDBusConnection. All calls to RawDBusConnection are invoked on
the I/O thread, so the sender tasks only impose an overhead.
Currently DBusWatcher registers read and write watchers on
the I/O thread unconditionally. Thus for read-only DBusWatch
structures, the write watcher on the I/O thread generates a
significant amount of CPU overhead by constantly reporting
success via calls to OnFileCanWriteWithoutBlocking.
This patch changes DBusWatcher to respect the status flags
of supplied DBusWatch structures. It will only poll for
read or write status if the DBus watch has the corresponding
flag set.
DBus keeps track of these flags and calls the toggle callback
when it needs to wait on a certain DBusWatch.
This patch converts DBusWatcher to run on the I/O thread. When a
caller starts DBus, StartDBus creates a new connection and adds
it to the I/O thread's poll loop. DBusWatchers are created and
removed automatically by the DBus libary.
The I/O thread provides all features of the DBus thread. So most
of the existing code has been removed or rewritten. The former
includes the control socket and the DBus thread, the latter is in
the DBusWatcher code.
Using a private DBus connection gives each of its users, such as
Bluetooth, its own connection to the DBus server. This simplifies
the use of DBusWatch structures and ensures that all resources of
a connection are free'd when the connection gets closed.
Bluetooth maintains two connections to the DBus server and the DBus
system itself maintains a third one. This implies some overhead and
makes the code more difficult to understand.
This patch changes the Bluetooth code to use the connection that is
established by the DBus system.
DBusWatcher::Poll currently breaks after reading DBus data from the
socket. Thus, it never processes the data and dispatches the DBus
messages. This patch fixes the code to dispatch DBus messages after
reading the DBus socket.
This patch changes the DBus shutdown to only cleanup the DBus
thread from the main thread after DBusWatcher has completed.
This should ensure that the main thread will not have to wait
for the DBus thread.
