4f3327cd41 Extend dns_db_allrdatasets to control interation results
Add an options parameter to control what rdatasets are returned when
iteratating over the node.  Specific modes will be added later.

79b7804ce8 Consistenly use UNREACHABLE() instead of ISC_UNREACHABLE()
In couple places, we have missed INSIST(0) or ISC_UNREACHABLE()
replacement on some branches with UNREACHABLE().  Replace all
ISC_UNREACHABLE() or INSIST(0) calls with UNREACHABLE().

b624be2544 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as a suggestion to inline a function is obsolete.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.

75f9dd8e82 Simplify way we tag unreachable code with only ISC_UNREACHABLE()
Previously, the unreachable code paths would have to be tagged with:

    INSIST(0);
    ISC_UNREACHABLE();

There was also older parts of the code that used comment annotation:

    /* NOTREACHED */

Unify the handling of unreachable code paths to just use:

    UNREACHABLE();

The UNREACHABLE() macro now asserts when reached and also uses
__builtin_unreachable(); when such builtin is available in the compiler.

2bf7921c7e 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.

f0989bdf03 The dns_message_create() cannot fail, change the return to void
The dns_message_create() function cannot soft fail (as all memory
allocations either succeed or cause abort), so we change the function to
return void and cleanup the calls.

14fe6e77a7 Always check the return from isc_refcount_decrement.
Created isc_refcount_decrement_expect macro to test conditionally
the return value to ensure it is in expected range.  Converted
unchecked isc_refcount_decrement to use isc_refcount_decrement_expect.
Converted INSIST(isc_refcount_decrement()...) to isc_refcount_decrement_expect.

af14091f65 Refactor the isc_log API so it cannot fail on memory failures
The isc_mem API now crashes on memory allocation failure, and this is
the next commit in series to cleanup the code that could fail before,
but cannot fail now, e.g. isc_result_t return type has been changed to
void for the isc_log API functions that could only return ISC_R_SUCCESS.

b984a4b647 disable adding keys to keytable; only DS trust anchors can now be added
the internal keytable structure has not yet been changed, but
insertion of DS anchors is the only method now available.

NOTE: the keytable unit test is currently failing because of tests
that expect individual keynode objects to contain single DST key
objects.

854af5a353 allow DS trust anchors to be set in keytable
note: this is a frankensteinian kluge which needs further refactoring.

the keytable started as an RBT where the node->data points to a list of
dns_keynode structures, each of which points to a single dst_key.
later it was modified so that the list could instead point to a single
"null" keynode structure, which does not reference a key; this means
a trust anchor has been configured but the RFC 5011 refresh failed.

in this branch it is further updated to allow the first keynode in
the list to point to an rdatalist of DS-style trust anchors.  these will
be used by the validator to populate 'val->dsset' when validating a zone
key.

a DS style trust anchor can be updated as a result of RFC 5011
processing to contain DST keys instead; this results in the DS list
being freed.  the reverse is not possible; attempting to add a DS-style
trust anchor if a key-style trust anchor is already in place results
in an error.

later, this should be refactored to use rdatalists for both DS-style
and key-style trust anchors, but we're keeping the existing code for
old-style trust anchors for now.

5efa29e03a The final round of adding RUNTIME_CHECK() around dns_name_copy() calls
This commit was done by hand to add the RUNTIME_CHECK() around stray
dns_name_copy() calls with NULL as third argument.  This covers the edge cases
that doesn't make sense to write a semantic patch since the usage pattern was
unique or almost unique.

89b269b0d2 Add RUNTIME_CHECK() around result = dns_name_copy(..., NULL) calls
This second commit uses second semantic patch to replace the calls to
dns_name_copy() with NULL as third argument where the result was stored in a
isc_result_t variable.  As the dns_name_copy(..., NULL) cannot fail gracefully
when the third argument is NULL, it was just a bunch of dead code.

Couple of manual tweaks (removing dead labels and unused variables) were
manually applied on top of the semantic patch.

50e109d659 isc_event_allocate() cannot fail, remove the fail handling blocks
isc_event_allocate() calls isc_mem_get() to allocate the event structure.  As
isc_mem_get() cannot fail softly (e.g. it never returns NULL), the
isc_event_allocate() cannot return NULL, hence we remove the (ret == NULL)
handling blocks using the semantic patch from the previous commit.

4. Remove unused code: isc_appctx_set{taskmgr,sockmgr,timermgr}
