MS-DNSP uses the term "EntombedTime" in e.g. "2.2.2.2.4.23 DNS_RPC_RECORD_TS"
which is more descriptive than the generic "timestamp", and less likely to be
confused with dwTimestamp, which has been our curse. Let's make it grep-able,

Move of strcasecmp redefine to lib/util/safe_string.h in
https://gitlab.com/samba-team/samba/-/merge_requests/1507 broke build on
Fedora 33 with GCC 10.2.1 for those compilation units that use
ldb_att_cmp().
The reason for that is that ldb_attr_cmp() defined as
#define ldb_attr_cmp(a, b) strcasecmp(a, b)
because attribute names restricted to be ASCII by RFC2251 (LDAPv3 spec).
A solution is to add

Add new for_selftest option to SAMBA_BINARY() and SAMBA3_BINARY()
This allows us to be much more consistent (at least in the core Samba)
and documents clearly why the binary should not be installed.
Not modified are
- test_lp_load
- notifyd-tests
- gendrandperf
- test* from examples/libsmbclient
- dbwrap_torture
- split_tokens
- locktest2
- msgtest
- msg_sink
- msg_source
- versiontest
- rpc_open_tcp
- test_headers
As these are not tested in selftest so any change would also be
untested. Of course they probably should be added in a different
MR.
Also not modified (because they are not tests, nor part of the
build system) are:
- smb2mount
- notifydd
- log2pacp
- debug2html
- smbfilter
- destroy_netlogon_creds_cli
- spotlight2*
- tevent_glib_tracker
These do however appear to be untested.
For now, the source4 forked client tools are left unchanged:
- smbclient4
- nmblookup4
Finally, the heimdal binaries are left as install=False as
they are either part of the build system or end-user tools
that we just don't want to install. These are however tested.
The motivation is commit like c34ec003b7
and da87fa998a, which are both totally
correct but are not needed if the selftest is not run on MacOS.
There are likely other platforms or build environments where building
our test binaries is more pain than valuable, see for example also

EnumDomainUsers currently takes too long, significantly slowing down
calls to winbind's getpwent which is a core unix API. The time is taken
up by a GUID lookup for every record in the cached result. The advantages
of this approach are:
1. It meets the specified requirement that if a record yet to be returned
by a search in progress (with a resume handle) is deleted or
modified, the future returned results correctly reflect the
new changes.
2. Memory footprint for a search in progress is only 16 bytes per record.
But, those benefits are not worth the significant performance hit
of the lookups, so this patch changes the function to run the search
and cache the RIDs and names of all records matching the search when
the request is made. This makes the memory footprint around 200 bytes
per record or up to 2MB per concurrent search for a 100k user database.
The speedup achieved by this change is around 50%, and in tandem with
some winbindd improvements as part of the same task has achieved around
15x speedup for getpwent.
The lost specification compliance is unlikely to cause a problem for any
known usage of this RPC call.

It's enough to check the auth_type for DCERPC_AUTH_TYPE_SCHANNEL,
there's no need to also check the auth_level for integrity or privacy.

Note: This fixes the failing test added previously, but that test still fails

- prefork process model, inhibit_pre_fork = true
immediately after the task_init
- prefork process model, inhibit_pre_fork = false
after each service worker has forked. It is not run on the service
master process.
The post fork hook is not called in the standard model if a new process
is forked on a new connection. It is instead called immediately after
the task_init.
The task_init hook has been changed to return an error code. This ensures
the post_fork code is only run if the task_init code completed successfully.
