Thanks ghedo
* Definitions

and isDuplicate
* Goodbye lenient functions
Now private key=value pairs have to be defined as structs too. They are no longer automatically named as KeyNNNNN
* Encode/decode
* Experimental svc
* Read method
* Implement some of the methods, use trick...
to report where the error is while reading it. This should be applied to EDNS too. Todo: Find if case can only contain e := new(SVC_ALPN) and rest moved out
Also fix two compile errors
* Add SVC_LOCAL methods, reorder, remove alpn value, bugs
* Errors
* Alpn, make it build
* Correct testsuite
* Fully implement parser
Change from keeping a state variable to reading in one iteration until the key=value pair is fully consumed
* Simplify and document
EDNS should be simplified too
* Attempt to fix fuzzer
And Alpn bug
* A bug and change type values to match @ghedo's implementation
* IP bug
Also there are two ip duplicating patterns, one with copy, one with append. Maybe change it to be consistent.
* Check for strictly increasing keys as required
* Don't panic on invalid alpn
* Redundant check, don't modify original array
* Size calculation
* Fix the fuzzer, match the style
* 65535 is reserved too, don't delay errors
* Check keyNNN, check for aliasform having values
* IPvNHint is an array
* Fix ipvNHint
* Rename everything
* Unrecognized keys according to the updated specification
* Skip zero-length structs in generators. Fix CI
* Doc cleanup
* Off by one
* Add parse tests
* Check if private key doesn't collide with known key, invalid tests
* Disallow IPv4 as IPv6. More tests.
Related #1107
* Style fixes
* More consistency, more tests
* 🐛 Deep copy as in the documentation
a := make([]net.IP, 1)
a[0] = net.ParseIP("1.1.1.1").To4()
b := append(make([]net.IP, 0, 1), a...)
b[0] = net.ParseIP("3.1.1.1").To4()
fmt.Println(a[0][0])
* Make tests readable
* Move valid parse tests to different file
* 🐛 One of previous commits not fully committed
* Test binary single value encoding/decoding and full encode/decode
* Add worst-case grows to builders, 🐛 Wrong visible character range, redundant tests
* Testing improvements
And don't convert to IPv4 twice
* Doc update only
* Document worst case allocations
and ipv6 can be at most of length 39, not 40
* Redundant IP copy, consistent IPv6 behavior, fix deep copy
* isDuplicate for SVCB
* Optimizations
* echoconfig
* Svc => SVCB
* Fix CI
* Regenerate after REBASE (2)
Rebased twice on 15th and 20th May
* Rename svc, use escapeByte.
* Fix parsing whitespaces between quotes, rename ECHOHOConfig
* resolve
Remove svcbFieldLen
Use reverseInt
Uppercase SVCB
Rename key_value
"invalid" => bad

Replace all the private methods in the EDNS0 with public methods.
Additionally, as suggested in issue #857, made Pack receive a
pre-allocated byte array, introduce a Len method, and have Pack
and Unpack return the number of octets written and read (respectively)
if there was no error.
Closes#857
* - implement deep-copy for OPT records + simple UT
* - adding ztypes.go (generated).
* - properly comment the specific behavior for EDNS0
* - remove too narrow UT + down-scope copy() method to package level only
* - tune comment
Sorely missing from this library. Add it. As there is no presentation
format the String method for this type puts a comment in front of it.

* Stop compressing names in RT records
Although RFC 1183 allows names in the RT record to be compressed with:
"The concrete encoding is identical to the MX RR."
RFC 3597 specifically prohibits compressing names in any record not
defined in RFC 1035.
* Add comment to RT struct regarding compression
* Remove fullSize return from compressionLenSearch
This wasn't used anywhere but TestCompressionLenSearch, and was very
wrong.
* Add generated compressedLen functions and use them
This replaces the confusing and complicated compressionLenSlice
function.
* Use compressedLenWithCompressionMap even for uncompressed
This leaves the len() functions unused and they'll soon be removed.
This also fixes the off-by-one error of compressedLen when a (Q)NAME
is ".".
* Use Len helper instead of RR.len private method
* Merge len and compressedLen functions
* Merge compressedLen helper into Msg.Len
* Remove compress bool from compressedLenWithCompressionMap
* Merge map insertion into compressionLenSearch
This eliminates the need to loop over the domain name twice when we're
compressing the name.
* Use compressedNameLen for NSEC.NextDomain
This was a mistake.
* Remove compress from RR.len
* Add test case for multiple questions length
* Add test case for MINFO and SOA compression
These are the only RRs with multiple compressible names within the same
RR, and they were previously broken.
* Rename compressedNameLen to domainNameLen
It also handles the length of uncompressed domain names.
* Use off directly instead of len(s[:off])
* Move initial maxCompressionOffset check out of compressionLenMapInsert
This should allow us to avoid the call overhead of
compressionLenMapInsert in certain limited cases and may result in a
slight performance increase.
compressionLenMapInsert still has a maxCompressionOffset check inside
the for loop.
* Rename compressedLenWithCompressionMap to msgLenWithCompressionMap
This better reflects that it also calculates the uncompressed length.
* Merge TestMsgCompressMINFO with TestMsgCompressSOA
They're both testing the same thing.
* Remove compressionLenMapInsert
compressionLenSearch does everything compressionLenMapInsert did anyway.
* Only call compressionLenSearch in one place in domainNameLen
* Split if statement in domainNameLen
The last two commits worsened the performance of domainNameLen
noticably, this change restores it's original performance.

* Remove stray newline from TestMsgCompressionMultipleQuestions
* Remove stray newline in length_test.go
This was introduced when resolving merge conflicts.
copyHeader() is redundant, we allocate a header and then copy the
non-pointer elements into it; we don't need to do this, because if we
just asssign rr.Hdr to something else we get the same result.
Remove copyHeader() and the generation and use of it in ztypes.go.
This was missing and generated the wrong code for TKEY; it adds a +1 to
the amount. This should happen (technically).
I think the fallout is not super bad (of the +1) as we allocate a byte
more for when pack a message.
Implement the CSYNC record.
Fixes#290
Long overdue, lets add this record. Similar in vain as NSEC/NSEC3, we
need to implement len() our selves. Presentation format parsing and
tests are done as well.
This is CoreDNS running with CSYNC support, `dig` doesn't support this
at the moment, so:

1) Refactoring of tlsa.go
- moved routine to create the certificate rdata to its own go module
as this is shared between TLSA and SMIMEA records
2) Added support for creating an SMIMEA domain name
3) Developed in accordance with draft-ietf-dane-smime-12 RFC
Miek,
Submitting for your review. Happy to make any recommended changes or
address omissions.
Lightly tested against our internal DNS service which hosts DANE
SMIMEA records for our email certificates.
Parse tests are added.
Update the size-xxx-member tags to point to another field in the struct
that should be used for the length in that field. Fix NSEC3/HIP and TSIG
to use to this and generate the correct pack/unpack functions for them.
Remove IPSECKEY from the lib and handle it as an unknown record - it is
such a horrible RR, needed kludges before - now just handle it as an
unknown RR.
All types now use generated pack and unpack functions. The blacklist is
removed.
Remove the use of reflection when packing and unpacking, instead
generate all the pack and unpack functions using msg_generate.
This will generate zmsg.go which in turn calls the helper functions from
msg_helper.go.
This increases the speed by about ~30% while cutting back on memory
usage. Not all RRs are using it, but that will be rectified in upcoming
PR.
Most of the speed increase is in the header/question section parsing.
These functions *are* not generated, but straight forward enough. The
implementation can be found in msg.go.
The new code has been fuzzed by go-fuzz, which turned up some issues.
All files that started with 'z', and not autogenerated were renamed,
i.e. zscan.go is now scan.go.
Reflection is still used, in subsequent PRs it will be removed entirely.
