- This patch makes sure that we don't create nsDNSService on both child process and middleman process.
- gNeckoChild won't be created in middleman process, so it's fine to create ChildDNSService on middleman process.
- Add some MOZ_DIAGNOSTIC_ASSERT in TRR, so we know where TRR is used on child process.

The DNS service was shutdown and restarted again in several scenarios,
for example when one of its prefs changed and by nsIOService when going
offline/online. The DNSService restart dragged the resolver, TRRService
and others with it and they too were thus restarted.
Most notably this hurt TRR resolving, as the restart caused short gaps
in time when there was no TRRService available and nsHostResolver
defaults to TRR Mode "native" if there's no TRRservice up, causing the
name resolver to occasionally use the wrong or unexpected resolver even
though TRR is enabled.
The resolver restart also flushed the DNS cache which is now avoided.
It is also a performance gain.

Provides an optional resolver mechanism for Firefox that allows running
together with or instead of the native resolver.
TRR offers resolving of host names using a dedicated DNS-over-HTTPS server
(HTTPS is required, HTTP/2 is preferable).
DNS-over-HTTPS (DOH) allows DNS resolves with enhanced privacy, secure
transfers and improved performance.
To keep the failure rate at a minimum, the TRR system manages a dynamic
persistent blacklist for host names that can't be resolved with DOH but works
with the native resolver. Blacklisted entries will not be retried over DOH for
a couple of days. "localhost" and names in the ".local" TLD will not be
resolved via DOH.
TRR is preffed OFF by default and you need to set a URI for an available DOH
server to be able to use it. Since the URI for DOH is set with a name itself,
it may have to use the native resolver for bootstrapping. (Optionally, the
user can set the IP address of the DOH server in a pref to avoid the required
initial native resolve.)
When TRR starts up, it will first verify that it works by checking a
"confirmation" domain name. This confirmation domain is a pref by default set
to "example.com". TRR will also by default await the captive-portal detection
to raise its green flag before getting activated.
All prefs for TRR are under the "network.trr" hierarchy.

This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

We have several different methods called OnLookupComplete, with similar but different arguments.
This makes it difficult to reason about the code, when lots of methods are called the same.
* renames nsResolveHostCallback.OnLookupComplete to nsResolveHostCallback.OnResolveHostComplete
* renames nsHostResolver.OnLookupComplete to nsHostResolver.CompleteLookup
