This patch adds:
* tests that we restart the TRR connection if it gets abnormally shut down
* a way to terminate the TRR connection when attempting to resolve closeme.com
* makes sure that resolving excluded domains with the DISABLE_TRR flag does
not fail. Before this we would return an error code without checking the
excluded domains first.

This test uses prefs added in Bug 1518730, but the pref is ignored when it
doesn't exist, so the test is still valid.

This patch uses the existing xpcshell test certificate infrastructure
(pycert/pykey) to manage the http2 test certificates (and gets rid of some uses
of nsIBadCertListener2 as a bonus).

... and before chasing a cname, check if the address record for that
CNAME is actually in fact already provided in the DNS packet that passed
on the CNAME!
Some existing tests ajusted for this. Two new tests added.

In the section of the response body parser that just skips over the
answer section, the code wrongly assumed there could only be a pointer
at the start, while in fact every label can be made as a pointer. Just
turned out to not be used very often.

RFC 1035 section 4.1.1 documents this bit as:
RD - Recursion Desired - this bit may be set in a query and is copied
into the response. If RD is set, it directs the name server to pursue
the query recursively. Recursive query support is optional.

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.
