Winbind can ask rpcd_lsad for LookupNames etc. This can recurse back
into winbind for getpwnam. We have the "_NO_WINBINDD" environment
variable set in winbind itself for this case, but this is lost on the
way into rpcd_lsad. Use a flag in global_sid_Samba_NPA_Flags to pass
this information to dcerpc_core, where it sets the variable on every
call if requested.

These are produced by editing `python/samba/test/sddl.py to enable
`test_write_test_strings`, the running `make test TESTS='sddl\\b'`.
The windows executable from the C file added in a recent commit can
run these tests using the `-i` flag.
The Samba sddl.py tests can be induced to use them too, but that is
only useful for showing they are still in sync.

prior to this patch rights matching "FA", "FR", "FW", "FX" were
outputted as the hex string representing the bit value.
While outputting the hex string is perfectly fine, it makes it harder
to compare icacls output (which always uses the special string values)
Additionally adjust various tests to deal with use of shortcut access masks
as sddl format now uses FA, FR, FW & FX strings (like icalcs does) instead
of hex representation of the bit mask.
adjust
samba4.blackbox.samba-tool_ntacl
samba3.blackbox.large_acl
samba.tests.samba_tool.ntacl
samba.tests.ntacls

Our previous behaviour (at least with glibc) was to clip off the extra
bits, so that 0x123456789 would become 0x23456789. That's kind of the
obvious thing, but is not what Windows does, which is to saturate the
value, rounding to 0xffffffff. The effect of this is to turn on all
the flags, which quite possibly not what you meant.
Now we just return an error.

The string "S:D:P" is parsed by us and Windows into a valid struct,
which has an empty DACL with the PROTECTED flag, and an empty SACL.
This is reconstructed in canonical order as "D:PS:", which Windows
will correctly parse, but Samba has assumed the "S" is a bad DACL
flag. Now we don't make that assumption.

These occur canonically when the indentifier authority is > 2^32, but
also are accepted by Windows for any number.
There is a tricky case with an "O:" or "G:" SID that is immediately
followed by a "D:" dacl, because the "D" looks like a hex digit. When
we detect this we need to subtract one from the length.
We also need to do look out for trailing garbage. This was not an
issue before because any string caught by the strspn(...,
"-0123456789") would be either rejected or fully comsumed by
dom_sid_parse_talloc(), but with hex digits, a string like
"S-1-1-2x0xabcxxx-X" would be successfully parsed as "S-1-1-2", and
the "x0xabcxxx-X" would be skipped over. That's why we switch to using
dom_sid_parse_endp(), so we can compare the consumed length to the
expected length.
