Backport patches to fix CVE-2019-6471 and CVE-2018-5743 for bind.
CVE-2019-6471 is fixed by 0001-bind-fix-CVE-2019-6471.patch and the
other 6 patches are for CVE-2018-5743. And backport one more patch to
fix compile error on arm caused by these 6 commits.

+Subject: [PATCH 1/6] fix enforcement of tcp-clients (v1)
+
+tcp-clients settings could be exceeded in some cases by
+creating more and more active TCP clients that are over
+the set quota limit, which in the end could lead to a
+DoS attack by e.g. exhaustion of file descriptors.
+
+If TCP client we're closing went over the quota (so it's
+not attached to a quota) mark it as mortal - so that it
+will be destroyed and not set up to listen for new
+connections - unless it's the last client for a specific
+interface.

+Subject: [PATCH 2/6] tcp-clients could still be exceeded (v2)
+
+the TCP client quota could still be ineffective under some
+circumstances. this change:
+
+- improves quota accounting to ensure that TCP clients are
+ properly limited, while still guaranteeing that at least one client
+ is always available to serve TCP connections on each interface.
+- uses more descriptive names and removes one (ntcptarget) that
+ was no longer needed
+- adds comments
+

+Subject: [PATCH 4/6] better tcpquota accounting and client mortality checks
+
+- ensure that tcpactive is cleaned up correctly when accept() fails.
+- set 'client->tcpattached' when the client is attached to the tcpquota.
+ carry this value on to new clients sharing the same pipeline group.
+ don't call isc_quota_detach() on the tcpquota unless tcpattached is
+ set. this way clients that were allowed to accept TCP connections
+ despite being over quota (and therefore, were never attached to the
+ quota) will not inadvertently detach from it and mess up the
+ accounting.
+- simplify the code for tcpquota disconnection by using a new function
+ tcpquota_disconnect().
+- before deciding whether to reject a new connection due to quota
+ exhaustion, check to see whether there are at least two active
+ clients. previously, this was "at least one", but that could be
+ insufficient if there was one other client in READING state (waiting
+ for messages on an open connection) but none in READY (listening
+ for new connections).
+- before deciding whether a TCP client object can to go inactive, we
+ must ensure there are enough other clients to maintain service
+ afterward -- both accepting new connections and reading/processing new
+ queries. A TCP client can't shut down unless at least one
+ client is accepting new connections and (in the case of pipelined
+ clients) at least one additional client is waiting to read.
+

+Subject: [PATCH 5/6] refactor tcpquota and pipeline refs; allow special-case
+ overrun in isc_quota
+
+- if the TCP quota has been exceeded but there are no clients listening
+ for new connections on the interface, we can now force attachment to the
+ quota using isc_quota_force(), instead of carrying on with the quota not
+ attached.
+- the TCP client quota is now referenced via a reference-counted
+ 'ns_tcpconn' object, one of which is created whenever a client begins
+ listening for new connections, and attached to by members of that
+ client's pipeline group. when the last reference to the tcpconn
+ object is detached, it is freed and the TCP quota slot is released.
+- reduce code duplication by adding mark_tcp_active() function.
+- convert counters to atomic.
+

+Subject: [PATCH 6/6] restore allowance for tcp-clients < interfaces
+
+in the "refactor tcpquota and pipeline refs" commit, the counting
+of active interfaces was tightened in such a way that named could
+fail to listen on an interface if there were more interfaces than
+tcp-clients. when checking the quota to start accepting on an
+interface, if the number of active clients was above zero, then
+it was presumed that some other client was able to handle accepting
+new connections. this, however, ignored the fact that the current client
+could be included in that count, so if the quota was already exceeded
+before all the interfaces were listening, some interfaces would never
+listen.
+
+we now check whether the current client has been marked active; if so,
+then the number of active clients on the interface must be greater
+than 1, not 0.
+
+(cherry picked from commit 0b4e2cd4c3192ba88569dd344f542a8cc43742b5)

Drop backports, rebase a couple of patches.
This is the second last release of py 2.x; upstream support ends on
1 January 2020, there will be one final 2.x afterwards.
Note that the only thing that still needs python 2.x in oe-core is
u-boot; when the next u-boot update arrives, we should find out
where the py3 migration is for that component before merging the
update.

-
-This change skips parsing of email addresses where domains include a "@" character, which can be maliciously used since the local part is returned as a complete address.
-
-(cherry picked from commit 8cb65d1381b027f0b09ee36bfed7f35bb4dec9a9)
-
-Excludes changes to Lib/email/_header_value_parser.py, which did not

+When cross compiling python, we used to need to install the Makefile, pyconfig.h
+and the python library to their final location before being able to compile the
rest of python. This change allows us to point python at its own source when
building, avoiding a variety of sysroot staging issues and simplifying the main
python recipe.

-Subject: [PATCH] bpo-30458: Disallow control chars in http URLs (GH-12755)
- (GH-13154) (GH-13315)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Disallow control chars in http URLs in urllib2.urlopen. This
-addresses a potential security problem for applications that do not
-sanity check their URLs where http request headers could be injected.
-
-Disable https related urllib tests on a build without ssl (GH-13032)
-These tests require an SSL enabled build. Skip these tests when
-python is built without SSL to fix test failures.
-
-Use httplib.InvalidURL instead of ValueError as the new error case's
-exception. (GH-13044)
-
-Backport Co-Authored-By: Miro Hrončok <miro@hroncok.cz>
-
-(cherry picked from commit 7e200e0763f5b71c199aaf98bd5588f291585619)
-
-Notes on backport to Python 2.7:
-
-* test_urllib tests urllib.urlopen() which quotes the URL and so is
- not vulerable to HTTP Header Injection.
-* Add tests to test_urllib2 on urllib2.urlopen().
-* Reject non-ASCII characters: range 0x80-0xff.
