b7ae514b3b fix out-of-tree mem_test
Previously changed mem_test (!10320) introduces a test which checks for
the value of `__FILE__`, which is different if the build is done
out-of-tree or not, even though this is not relevant for the test (only
the base filename is). This result in a broken test for out-of-tree
builds. Fix this by changing the way the "grep" is done in the test,
ignoring the optional path prefix in the filename.

4eb2cd364a copy __FILE__ when allocating memory
When allocating memory under -m trace|record, the __FILE__ pointer is
stored, so it can be printed out later in order to figure out in which
file an allocation leaked. (among others, like the line number).

However named crashes when called with -m record and using a plugin
leaking memory. The reason is that plugins are unloaded earlier than
when the leaked allocations are dumped (obviously, as it's done as late
as possible). In such circumstances, __FILE__ is dangling because the
dynamically loaded library (the plugin) is not in memory anymore.

Fix the crash by systematically copying the __FILE__ string
instead of copying the pointer. Of course, this make each allocation to
consume a bit more memory (and longer, as it needs to calculate the
length of __FILE__) but this occurs only under -m trace|record debugging
flags.

In term of unit test, because grepping in C is not fun, and because the
whole "syntax" of the dump output is tested in other tests, this simply
search for a substring in the whole buffer to make sure the expected
allocations are found.

ad2c3fa4f7 IPv6 case to isc_netaddr_masktoprefixlen tests
Unit test for isc_netaddr_masktoprefixlen were missing IPv6 mask cases.
Add those and few other IPv4 cases. Also, the test is refactored in
order to make it easy to add new cases.

Replace isc_mem_destroy() with isc_mem_detach()
Remove legacy isc_mem_destroy() and just use isc_mem_detach() as
isc_mem_destroy() doesn't play well with call_rcu API.

unify fips handling to isc_crypto and make the toggle one way
Since algorithm fetching is handled purely in libisc, FIPS mode toggling
can be purely done in within the library instead of provider fetching in
the binary for OpenSSL >=3.0.

Disabling FIPS mode isn't a realistic requirement and isn't done
anywhere in the codebase. Make the FIPS mode toggle enable-only to
reflect the situation.

Move the library init and shutdown to executables
Instead of relying on unreliable order of execution of the library
constructors and destructors, move them to individual binaries.  The
advantage is that the execution time and order will remain constant and
will not depend on the dynamic load dependency solver.

This requires more work, but that was mitigated by a simple requirement,
any executable using libisc and libdns, must include <isc/lib.h> and
<dns/lib.h> respectively (in this particular order).  In turn, these two
headers must not be included from within any library as they contain
inlined functions marked with constructor/destructor attributes.

77ec2a6c22 Cleanup the isc_counter unit

ISC_R_SUCCESS), use the macros to implement the reference counting,
little style cleanup, and expand the unit test.

53991ecc14 Refactor and simplify isc_symtab
This commit does several changes to isc_symtab:

1. Rewrite the isc_symtab to internally use isc_hashmap instead of
   hand-stiched hashtable.

2. Create a new isc_symtab_define_and_return() api, which returns
   the already defined symvalue on ISC_R_EXISTS; this allows users
   of the API to skip the isc_symtab_lookup()+isc_symtab_define()
   calls and directly call isc_symtab_define_and_return().

3. Merge isccc_symtab into isc_symtab - the only missing function
   was isccc_symtab_foreach() that was merged into isc_symtab API.

4. Add full set of unit tests for the isc_symtab API.

10accd6260 clean up uses of ISC_R_NOMEMORY
the isc_mem allocation functions can no longer fail; as a result,
ISC_R_NOMEMORY is now rarely used: only when an external library
such as libjson-c or libfstrm could return NULL. (even in
these cases, arguably we should assert rather than returning
ISC_R_NOMEMORY.)

code and comments that mentioned ISC_R_NOMEMORY have been
cleaned up, and the following functions have been changed to
type void, since (in most cases) the only value they could
return was ISC_R_SUCCESS:

- dns_dns64_create()
- dns_dyndb_create()
- dns_ipkeylist_resize()
- dns_kasp_create()
- dns_kasp_key_create()
- dns_keystore_create()
- dns_order_create()
- dns_order_add()
- dns_peerlist_new()
- dns_tkeyctx_create()
- dns_view_create()
- dns_zone_setorigin()
- dns_zone_setfile()
- dns_zone_setstream()
- dns_zone_getdbtype()
- dns_zone_setjournal()
- dns_zone_setkeydirectory()
- isc_lex_openstream()
- isc_portset_create()
- isc_symtab_create()

(the exception is dns_view_create(), which could have returned
other error codes in the event of a crypto library failure when
calling isc_file_sanitize(), but that should be a RUNTIME_CHECK
anyway.)

6691a1530d TLS SNI - add low level support for SNI to the networking code
This commit adds support for setting SNI hostnames in outgoing
connections over TLS.

Most of the changes are related to either adapting the code to accept
and extra argument in *connect() functions and a couple of changes to
the TLS Stream to actually make use of the new SNI hostname
information.

eec30c33c2 Don't enable SO_REUSEADDR on outgoing UDP sockets
Currently, the outgoing UDP sockets have enabled
SO_REUSEADDR (SO_REUSEPORT on BSDs) which allows multiple UDP sockets to
bind to the same address+port.  There's one caveat though - only a
single (the last one) socket is going to receive all the incoming
traffic.  This in turn could lead to incoming DNS message matching to
invalid dns_dispatch and getting dropped.

Disable setting the SO_REUSEADDR on the outgoing UDP sockets.  This
needs to be done explicitly because `uv_udp_open()` silently enables the
option on the socket.

cc167266aa Support ISO timestamps with timezone information
This commit adds support for timestamps in iso8601 format with timezone
when logging. This is exposed through the iso8601-tzinfo printtime
suboption.
It also makes the new logging format the default for -g output,
hopefully removing the need for custom timestamp parsing in scripts.

63659e2e3a
complete removal of isc_loop_current()
isc_loop() can now take its place.

This also requires changes to the test harness - instead of running the
setup and teardown outside of th main loop, we now schedule the setup
and teardown to run on the loop (via isc_loop_setup() and
isc_loop_teardown()) - this is needed because the new the isc_loop()
call has to be run on the active event loop, but previously the
isc_loop_current() (and the variants like isc_loop_main()) would work
even outside of the loop because it needed just isc_tid() to work, but
not the full loop (which was mainly true for the main thread).

use a thread-local variable to get the current running loop
if we had a method to get the running loop, similar to how
isc_tid() gets the current thread ID, we can simplify loop
and loopmgr initialization.

remove most uses of isc_loop_current() in favor of isc_loop().
in some places where that was the only reason to pass loopmgr,
remove loopmgr from the function parameters.
