The ndr token code keeps a temporary store of tokens which are
referred to a small number of times (often once) before being
discarded. The access patterns are somewhat stack-like, with recently
placed tokens being accessed most often.
The old code kept these tokens in a linked list, which we replace with
a self-resizing array.
This keeps everything roughly the same in big-O terms, but makes it
all faster in practice by vastly reducing the amount of tallocing and
pointer-chasing.
The peak memory use is strictly reduced. On a 64 bit machine each core
token struct fits in 16 bytes (after padding) while the two pointers
used by the DLIST add another 16 bytes, so the overall list allocation
is the same as the peak 2n array allocation -- except in the list case
it is dwarfed by the talloc and malloc metadata overhead.
Before settling on the resized arrays, we tried red-black trees, which
are bound to be better for large ndr structures. As it happens, we
don't deal with large structures (the size of replication clumps is
limited to 400 objects) and the asymptotic benefits of the trees are
not realised in practice.
With luck you should find graphs comparing the performance of these
various techniques at:
https://www.samba.org/~dbagnall/perf-tests/ndr-token/
This necessarily breaks the ABI because the linked list implementation
was publicly exposed.

This call will be done in the idmap child. It is not 100% the right place,
but there is no better one available to me. It will become a replacement
for the "winbind nss info" parameter: This global parameter is good
for just one domain. It might be possible to have idmap backend AD for
different domains, and the NSS info like primary gid, homedir and shell
might be done with different policies per domain. As we already have a
domain-specific idmap configuration, doing the NSS info configuration
there also is the closest way to do it.
The alternative, if we did not want to put this call into the idmap child
would be to establish an equivalent engine like the whole "idmap config
*" just for the nss info. But as I believe this is closely related,
I'll just keep it in the idmap child.
This also extends the wbint_userinfo structure with pretty much all user
related fields. The idea is that the GetNssInfo call can do whatever it
wants with it.
