69691dd0cd smbd: fix handling of sentinel timestamp values
This implements two core changes:

* use NTTIME instead of struct timespec at the database layer

* use struct timespec { .tv_nsec = SAMBA_UTIME_OMIT } as special sentinel
  value in smbd when processing timestamps

Using NTTIME at the database layer is only done to avoid storing the special
struct timespec sentinel values on disk. Instead, with NTTIME the sentinel value
for an "unset" timestamp is just 0 on-disk.

The NTTIME value of 0 gets translated by nt_time_to_full_timespec() to the
struct timespec sentinel value { .tv_nsec = SAMBA_UTIME_OMIT }.

The function is_omit_timespec() can be used to check this.

Beside nt_time_to_full_timespec(), there are various other new time conversion
functions with *full* in their name that can be used to safely convert between
different types with the changed sentinel value.

f2af647e7d lib: canonicalize pull_dos_date3()
Returns 0xFFFFFFFF as (time_t)-1. This avoids misenterpreting 0xFFFFFFFF as a
valid time_t value (0xFFFFFFFF = Sun 07 Feb 2106 06:28:15 AM GMT) on 64-bit
platforms where time_t is 64-bit.

Currently direct and indirect callers of pull_dos_date3() rely on the fact that
the resulting time_t is checked with null_time() which also checks for
0xFFFFFFFF as sentinel value amongst 0 and -1:

        return t == 0 ||
                t == (time_t)0xFFFFFFFF ||
                t == (time_t)-1;

By returning -1 instead of 0xFFFFFFFF, callers can safely pass the result to
unix_to_nt_time() which *doesn't* check for 0xFFFFFFFF, only -1.

d95be91358 s3:tests: add a blackbox test that confirms broken timestamp behaviour
This blackbox test confirms that Samba returns NTTIME=0 when a filesystem object
has a UNIX timestamp value of 0, ie UNIX epoch start 1.1.1970.

Here's an example output from running smbstatus allinfo on such a file:

  $ bin/smbclient -U slow%x //localhost/test -c "allinfo time_0_1970"
  altname: T11662~T
  create_time:    NTTIME(0)
  access_time:    NTTIME(0)
  write_time:     NTTIME(0)
  change_time:    NTTIME(0)
  attributes:  (80)
  stream: [::$DATA], 0 bytes

If you look at it with smbclient ls command, it munges the output to be 1970 so
you don't notice the problem:

  $ bin/smbclient -U slow%x //localhost/test -c "ls time_0_1970"
    time_0_1970                         N        0  Thu Jan  1 01:00:00 1970

The test also test other time_t values -1 and 4294967295 that are used as
sentinel values in Samba code and shows that handling these values is equally
broken.

Same for time_t values < -1.

Note that I'm adding a blackbox test *and* a torture test, as with this blackbox
test I can directly control the server side, but with smbtorture I have to go
through the SMB stack to create the files which doesn't work currently.

e30607aff3 s4/smb_server: Fix handling of SMB2 messages after Netbios session setup
On receiving a special NBT packet (e.g. session setup) the samba daemon
effectively sets up SMB1 as the negotiated protocol (in terms of
software handling of the messages) even though no SMB protocol
has yet been negotiated. If the next message after the nbt session setup
is a SMB2 message it will be handled by the SMB1 callbacks and will be
rejected. This is evident when using smbclient (with -p 139) option
in an env where SMB1 cannot be negotiated [*]

This change doesn't set up the SMB1 callbacks on receipt of NBT special
messages but lets the generic callback in place. Once either SMB1 (or)
SMB2 is established (by receipt of a 'real' SMB or >=SMB2 message) then
the proper callbacks will be set as normal.

On failure, we jump to the teardown function. The pointer for
debug_string isn't valid anymore, but the ldb debug system still points
to that address, and when we store the location of the allocated string,
we overwrite memory, in that case something from talloc and a
talloc_free() then jumps into the nirvana.
