536a84935c ndr_orpc: properly allocate empty DUALSTRINGARRAY
When there is no data we still need to allocate for the terminating NULL.

Found by Michael Hanselmann using Honggfuzz and an fuzzer for Samba's
NDR layer.

83b1c21dd0 librpc: Do not return an NDR table for a zero GUID
The source3 RPC server will do a lookup by GUID and should
not be returned a table for a zero GUID.

Thankfully such a pipe would also need to have been registered
but regardless this is not a determinsitic result so should
be avoided.

6ef6ddce5a shift read_hex_bytes() and parse_guid_string() into lib/util
read_hex_bytes() is going to be used in lib/util/rfc1738.c.

parse_guid_string() is shifted for two reasons: Firstly, it is called
very often in some operations, sometimes constituting a few percent of
the CPU load, and it makes several calls to read_hex_bytes(). We want
the compiler to be able to inline those calls if it thinks that is
wise. Secondly, there are other places that could do with fast GUID
parsing.

70923b7521 ndr: Use resizing array instead of linked lists (breaking ABI)
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.
