A simple samba-tool shell, can be quite useful to play around with the ldb database and models.
All models get imported and the samdb connection variable made available.
Example usage:
bin/samba-tool shell -H <host> --workgroup <workgroup> --realm <realm>
>>> silos = AuthenticationSilo.query(ldb)
>>> for silo in silos:
... print(silo)

This method is now consistent with the other ‘add_*_record()’ methods.

As with the previous commit, though not addressing the particular fuzz
case, zero hex numbers need to be explicitly written as "0x0", or the
round-trip will fail.

The string "00" will decode into an integer tagged as octal, but
`snprintf("%#oll")` will write the string "0", which would decode as
decimal, so the in the SDDL1->SD1->SDDL2->SD2 round trip, SD1 would
not be the same as SD2.
The effect is really only relevant to SDDL, which wants to remember
what base the numbers were presented in, though the fuzzers and tests
don't directly compare SDDL, which can have extra spaces and so forth.

For this purpose, "too many" means we know for sure that it won't fit
in packet format, even if all the ACEs are minimum size. This would
fail anyway.
Credit to OSS-Fuzz, who found that 50 thousand ACEs that took more
than 60 seconds to decode. This will now fail after 4096 ACEs which
should be about 150 times faster than 50k (because the realloc loop in
quadratic), so ~0.5 seconds in the fuzz context with sanitisers
enabled. That is still slowish, but SDDL parsing is not a critical
path and without address sanitisers it will be many times faster.

When translating a Unix ID to a SID the module calls get[pwu|grg]id() but the
name returned by some NSS modules might be a UPN instead of a plain name. If
the new parameter is enabled the returned name will be parsed and correctly
handled.
On the other hand, when translating a SID to a Unix ID the module first
resolves the SID to a domain + name, and then calls get[pw|gr]name() with the
plain name, or the UPN if the new parameter is enabled.
