The advantage of the new functions is there (except for print, which
is unchanged) is an error raised when the token is not found, so
we can be confident in the changes to the token behaviour.

603f23b19c pidl: Generate and consume the switch level token for both NDR_SCALARS and NDR_BUFFERS in ndr_pull()
This means what was previously a list becomes a single variable that
could be passed as a function paraemter, but this is avoided for now
because it would change the ABI and be more intrusive.

Before this, a client could cause a NDR token containing the swith level
to be allocated for each and every element in the array that they
promised they were sending (without having to actually send them).

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

This NDR fuzzer links with each "interface" in the IDL files to

It started as a copy of ndrdump but very little of that remains

The fancy build rules try to avoid needing a lof of boilerplate
in the wscript_build files and ensure new fuzzers are generated

aefce8e7c0 pidl s4::NDR::Parser: correct has_fast_array logic
Here we fix two bugs that cancelled each other out completely, so this
patch leaves us with exactly the same functionally as before.

Bug 1: In perl, return is *syntactically* a function.

That means 'return X or Y' is read as 'return(X) or Y', as in the
'open(X) or die "..."' construct -- Y is only evaluated if return
returns false. But return never returns, so Y is dead code. If in
doubt, try these:

perl -e "sub x {return 0 or die;} x"
perl -e "sub x {return (0 or die);} x"

What we *meant* here is 'return (X or Y)', BUT it turns out we were
confused -- the Y case was bogus.

Bug 2: string arrays never had "fast array logic" in the first place.

The fast array logic is for arrays of bytes, and can be fast (i.e.
memcpy) because there is no endianness to worry about. A string array
is an array of pointers not bytes.
