Given that these are almost exclusively called with <sal_uInt16>, I 
would simply un-template'ize the functions, substituting sal_uInt16 for 

For instantiations with prefix != sal_uInt16, I count four uses of 
read_lenPrefixed_uInt8s_ToOString<sal_uInt8>, two of 
read_lenPrefixed_uInt8s_ToOUString<sal_uInt8>, and one use of 
read_lenPrefixed_uInt8s_ToOString<sal_uInt32>.  All of them are reads, 
for which the functions in question are rather trivial, anyway.  I would 
just explicitly outline them at the call sites (or, if there are 
multiple calls from a single .cxx, add a local helper function).
