[1/2] Consolidate code to initialize nscd dataset header
Commit Message
Hi,
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.
Tested x86_64 with passwd, group and netgroup queries to verify that
there are no obvious regressions resulting from this change.

* nscd/nscd-client.h (datahead_init_common, datahead_init_pos,
datahead_init_neg): New functions.
* nscd/aicache.c (addhstaiX): Use them.
* nscd/grpcache.c (cache_addgr): Likewise.
* nscd/hstcache.c (cache_addhst): Likewise.
* nscd/initgrcache.c (addinitgroupsX): Likewise.
* nscd/netgroupcache.c (do_notfound): Likewise.
(addgetnetgrentX): Likewise.
(addinnetgrX): Likewise.
* nscd/pwdcache.c (cache_addpw): Likewise.
* nscd/servicescache.c (cache_addserv): Likewise.
