3a2c02424d Cache network interface information
Whenever getaddrinfo needed network interface information it used the
netlink interface to read the information every single time.  The
problem is that this information can change at any time.

The patch implements monitoring of the network interfaces through
nscd.  If no change is detected the previously read information can
be reused (which is the norm).  This timestamp information is also
made available to other processes using the shared memory segment
between nscd and those processes.

319b9ad4bc Generalize framework to register monitoring of files in nscd
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.

ea547a1a6e Fix a few asserts and IO calls in nscd.
The nscd/*cache.c files contain assert()s, writeall() and sendfileall() calls
that invalidly use together &dataset->resp and total where either dataset or
dataset->head.recsize should be used instead one of the components. In the
writeall() and sendfileall() cases, it is unlikely to matter in practice, but
the assertions can fail sometimes without a proper reason.

137028b4d7 Fix lock handling in memory hander of nscd.
The commit 20e498bd removes the pthread_mutex_rdlock() calls, but not the
corresponding pthread_mutex_unlock() calls. Also, the database lock is never
unlocked in one branch of the mempool_alloc() if.

I think unreproducible random assert(dh->usable) crashes in prune_cache() were
caused by this. But an easy way to make nscd threads hang with the broken
locking was.

nscd uses lockfree lists and we need to ensure the correct release
semantics is used when adding to the list.

5078fff6c4 Fix forced loop termination in nscd database lookup.
There are two issues with the forced loop exit in the nscd lookup:
1. the estimate of the entry size isn't pessimistic enough for all
   databases, resulting potentially is too early exits
2. the combination of 64-bit process and 32-bit nscd would lead to
   rejecting valid records in the database.

fa546abe9d Move BLOCK_ALIGN* macros back.
The move to nscd-client.h was only needed for some interim version
of the patch.  The final version doesn't need it.  Undo the change.

831a40494d Further robustify nscd database lookup.
We can compute an absolute maximum for the number of elements which
can fit into the currently mapped database.  Stop after that many
iterations.

cfe1fc1013 Robustify libc-side nscd database reader.
The nscd database mapped in processes can change at any time.  We
have to be more vigilant when it comes to using that memory.  Test
the data entries are valid in their entire size, don't read data
again from memory once we verified it, and make sure the trailing
pointer is not going off the deep end.

9e471dad8e Don't try to cleanup libselinux and libaudit.
Because we are not shutting down the other threads first another
thread might work on a query before the process shuts down.  In this
case the now uninitialized libselinux and libaudit might be used.
Just don't free the resources.  It's not necessary anyway because
the process is about to terminate.
