Subject: [PATCH 1/3] 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 2/3] Add a limit to the number of RR types for single name
Previously, the number of RR types for a single owner name was limited
only by the maximum number of the types (64k). As the data structure
that holds the RR types for the database node is just a linked list, and
there are places where we just walk through the whole list (again and
again), adding a large number of RR types for a single owner named with
would slow down processing of such name (database node).
Add a hard-coded limit (100) to cap the number of the RR types for a single
owner. The limit can be changed at the compile time by adding following
define to CFLAGS:
-DDNS_RBTDB_MAX_RTYPES=<limit>

Subject: [PATCH] Expand the list of the priority types and move it to db_p.h
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.

Subject: Be smarter about refusing to add many RR types to the database
Instead of outright refusing to add new RR types to the cache, be a bit
smarter:
1. If the new header type is in our priority list, we always add either
positive or negative entry at the beginning of the list.
2. If the new header type is negative entry, and we are over the limit,
we mark it as ancient immediately, so it gets evicted from the cache
as soon as possible.
3. Otherwise add the new header after the priority headers (or at the
head of the list).
4. If we are over the limit, evict the last entry on the normal header
list.

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)
