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.

Hex numbers in IDL are not parsed as numbers, resulting in warnings
like
Argument 0x2000 isn't numeric in numeric lt (<) at /home/douglas/src/samba/pidl/lib/Parse/Pidl/Samba4/NDR/Parser.pm line 981
not to mention problematic code. We add a utility function to convert
these numbers to numbers.
A typical difference this makes is:

Where the minimum ("0x2000" == 8192) was read as a string, thus
treated as zero.
The treatment as zero was introduced in 142b2a61f8a77b3065ce4c78b459ab714d6d190a
accidentially, which shows why warnings are important.
