1d807d84f1 Shrink decompression contexts
It's wasteful to use 20 bytes and a pointer indirection to represent
two bits of information, so turn the struct into an enum. And change
the names of the enumeration constants to make the intent more clear.

This change introduces some inline functions into another header,
which confuses `gcovr` when it is trying to collect code coverage
statistics. So, in the CI job, copy more header files into a directory
where `gcovr` looks for them.

129a522d88 There can no longer be multiple compression methods
The aim is to get rid of the obsolete term "GLOBAL14" and instead just
refer to DNS name compression.

This is mostly mechanically renaming

from	dns_(de)compress_(get|set)methods()
to	dns_(de)compress_(get|set)permitted()

and replacing the related enum by a simple flag, because compression
is either on or off.

20f0936cf2 Remove use of the inline keyword used as suggestion to compiler
Historically, the inline keyword was a strong suggestion to the compiler
that it should inline the function marked inline.  As compilers became
better at optimising, this functionality has receded, and using inline
as a suggestion to inline a function is obsolete.  The compiler will
happily ignore it and inline something else entirely if it finds that's
a better optimisation.

Therefore, remove all the occurences of the inline keyword with static
functions inside single compilation unit and leave the decision whether
to inline a function or not entirely on the compiler

NOTE: We keep the usage the inline keyword when the purpose is to change
the linkage behaviour.

bbaade23eb mem_maybedup() can no longer fail
mem_maybedup() calls isc_mem_allocate() if an mctx is supplied,
but that can no longer fail, so now the only way mem_maybedup()
could return NULL is if it was given a NULL source address by the
caller. this commit adds a REQUIRE to prevent that scenario, and
cleans up all the calling code that previously checked for NULL
return values.

this function is mostly used in rdata tostruct() implementations, so
the documentation for dns_rdata_tostruct() has been updated to
remove 'ISC_R_NOMEMORY' as a possible return value.

58bd26b6cf Update the copyright information in all files in the repository
This commit converts the license handling to adhere to the REUSE
specification.  It specifically:

1. Adds used licnses to LICENSES/ directory

2. Add "isc" template for adding the copyright boilerplate

3. Changes all source files to include copyright and SPDX license
   header, this includes all the C sources, documentation, zone files,
   configuration files.  There are notes in the doc/dev/copyrights file
   on how to add correct headers to the new files.

4. Handle the rest that can't be modified via .reuse/dep5 file.  The
   binary (or otherwise unmodifiable) files could have license places
   next to them in <foo>.license file, but this would lead to cluttered
   repository and most of the files handled in the .reuse/dep5 file are
   system test files.

b0a665d947 dns/rdata.c: Return void when ISC_R_SUCCESS is only returned value
With isc_mem_get() and dns_name_dup() no longer being able to fail, some
functions can now only return ISC_R_SUCCESS.  Change the return type to
void for the following function(s):

 * name_duporclone()

cd985d96e3 Add additional processing to HTTPS and SVBC records
The additional processing method has been expanded to take the
owner name of the record, as HTTPS and SVBC need it to process "."
in service form.

The additional section callback can now return the RRset that was
added.  We use this when adding CNAMEs.  Previously, the recursion
would stop if it detected that a record you added already exists.  With
CNAMEs this rule doesn't work, as you ultimately care about the RRset
at the target of the CNAME and not the presence of the CNAME itself.
Returning the record allows the caller to restart with the target
name.  As CNAMEs can form loops, loop protection was added.

As HTTPS and SVBC can produce infinite chains, we prevent this by
tracking recursion depth and stopping if we go too deep.

Both clang-tidy and uncrustify chokes on statement like this:

This commit uses a very simple semantic patch (below) to add braces around such
statements.

66af8713d8 lib/dns/rdata/*/*.c: Silence false positive nullPointerRedundantCheck warning from Cppcheck
Cppcheck gets confused by:

void bar(void *arg) {
    foo *data = arg;
    REQUIRE(source != NULL);
    REQUIRE(data->member != NULL);
}

and for consistency the DbC check needs to be changed to

void bar(void *arg) {
    foo *data = arg;
    REQUIRE(data != NULL);
    REQUIRE(data->member != NULL);
}
