nscd can clear caches when certain files change. The list of files
was hardcoded so far and worked for nss_files and nss_dns and those
modules which need no monitoring. nss_db, for instance, has its
own set of files to monitor. Now the NSS modules themselves can
request that certain files are monitored.
No longer is Berkeley db used. Instead a simple hash function is used.
The database files are not updated once they are created and therefore
no complicated database is needed.
I changed the files NSS backend for networks because I thought the
getent use of getnetbyaddr is correct. But it isn't. Undo parts
of the last change and fix getent.
There were two problems in the getnetbyaddr implementation. The type
argument is pretty much useless since (almost) no input file contains
this information and the NSS backends make up the value they fill in
for the n_addrtype field. Therefore we now declare that passing AF_UNSPEC
is always recognized. Secondly, the files backend didn't compare the network
numbers with the correct endianess.
Also change getent to take advantage of the type parameter change.
