Subject: [PATCH] Optimize the slabheader placement for certain RRTypes
Mark the infrastructure RRTypes as "priority" types and place them at
the beginning of the rdataslab header data graph. The non-priority
types either go right after the priority types (if any).
(cherry picked from commit 3ac482be7fd058d284e89873021339579fad0615)

Subject: [PATCH 1/2] Add a limit to the number of RRs in RRSets
Previously, the number of RRs in the RRSets were internally unlimited.
As the data structure that holds the RRs is just a linked list, and
there are places where we just walk through all of the RRs, adding an
RRSet with huge number of RRs inside would slow down processing of said
RRSets.
The fix for end-of-life branches make the limit compile-time only for
simplicity and the limit can be changed at the compile time by adding
following define to CFLAGS:
-DDNS_RDATASET_MAX_RECORDS=<limit>

Subject: [PATCH 1/2] Expand the list of the priority types
Add HTTPS, SVCB, SRV, PTR, NAPTR, DNSKEY and TXT records to the list of
the priority types that are put at the beginning of the slabheader list
for faster access and to avoid eviction when there are more types than
the max-types-per-name limit.
