This patch converts it to use Gecko strings instead of C strings, which makes
it much nicer.

This was created for B2G and isn't really useful otherwise. It only works on
Linux, and it's behind the memory.system_memory_reporter pref, which is false
by default.
The patch also removes LinuxUtils.{h,cpp}, which is no longer used.

This is needed for local developer builds to enable extended
telemetry recording by default. As a consequence, other subsystems
relying on this prefs will turn on (e.g. experiments, BHR, ...).

In Unified Telemetry toolkit.telemetry.enabled controls whether we send base
collection data or extended collection. The difference is mostly in volume, not
in kind (though extended collection has a little stricter testing and monitoring
requirements).
Since the Preferences UI change in Firefox 56, users no longer have the ability
to change toolkit.telemetry.enabled. This is a good thing as for pre-release
users very few disabled extended collection, and even fewer release users
enabled it. This provides uniform collection based on channel which should
eventually net us some efficiencies.
Until then we need to align our use of the toolkit.telemetry.enabled pref with
the UI change that has already shipped. This is accomplished by locking t.t.e
to 'true' on pre-release channels and locking it to 'false' on everything else.
This doesn't apply to Android as it doesn't (yet) use Unified Telemetry. t.t.e
means something rather different there.

This makes the code nicer. In particular, it removes many getter_Copies()
calls. The patch also converts a lot of nsCStrings to nsAutoCString, which will
avoid heap allocation in the common case.
The patch also renames PREF_CopyCharPref() as PREF_GetCStringPref(), because
it's actually getting a string, not a char, and that matches the existing
GetCString() and GetDefaultCString() methods. Correspondingly, it also renames
PREF_SetCharPref() as PREF_SetCStringPref().
The |aPrefName| arguments in nsIPrefBranch.idl remain as |string| because they
almost always involve passing in C string literals, and passing "foo" is much
nicer than passing NS_LITERAL_CSTRING("foo").
It's worth noting that early versions of this patch used |AUTF8String| instead
of |ACString|. But it turns out that libpref stores prefs internally as Latin1.
And |ACString| is compatible with Latin1 but |AUTF8String| isn't, because
non-ASCII Latin1 strings are not valid UTF-8!

First, the patch removes the return values from PrefTypeFlags::Set*(). They
allow chained calls, but they're barely used and they just make the code harder
to read.
Second, the patch changes pref_SetValue() to not modify and return the pref
flags. It's clearer if the flags changing is done separately. This requires
passing pref_SetValue() the old type instead of the flags.

At present, the "layout.css.stylo-blocklist.blocked_domains" pref is empty. It
is probably meaningless to set "layout.css.stylo-blocklist.enabled" pref to true
by default. We can set "layout.css.stylo-blocklist.enabled" pref to true by the
styloblocklist system add-on once the "layout.css.stylo-blocklist.blocked_domains"
pref is non-empty.

Right now, NS_GENERIC_FACTORY_SINGLETON_CONSTRUCTOR expects singleton
constructors to return already-addrefed raw pointers, and while it accepts
constructors that return already_AddRefed, most existing don't do so.
Meanwhile, the convention elsewhere is that a raw pointer return value is
owned by the callee, and that the caller needs to addref it if it wants to
keep its own reference to it.
The difference in convention makes it easy to leak (I've definitely caused
more than one shutdown leak this way), so it would be better if we required
the singleton getters to return an explicit already_AddRefed, which would
behave the same for all callers.
This also cleans up several singleton constructors that left a dangling
pointer to their singletons when their initialization methods failed, when
they released their references without clearing their global raw pointers.

Some odd touchpad utils give focus to window under mouse cursor when user tries
to scroll the content with swiping or something.
This is really odd behavior because some windows like popup windows doesn't
want focus. However, such ones do actually. For making easier to check such
device's behavior, we should have a pref to emulate such behavior.
