Consolidate code to initialize nscd dataset header
This patch consolidates the code to initialize the header of a dataset into a single set of functions (one for positive and another for negative datasets) primarily to reduce repetition of code. The secondary reason is to simplify Patch 2/2 which fixes the problem of an uninitialized byte in the header by initializing an unused field in the structure and hence preventing a possible data leak into the cache file.
