rrd_random() is a wrapper around random() that ensures the PRNG is seeded
exactly ONCE per process.

rrd_utils.c is introduced for functions that do not have a better home. --kevin

This patch consolidates several aspects of the command handling in
rrdcached:

* all commands, help, and context information is reduced to a single data
structure.

* all checks for command validity (context and permission) are handled in
the main dispatch routine

This removes duplicate help/syntax text, and long if..elseif..else chains.
It facilitates the addition of new commands. -- kevin

Even though POSIX/XSI requires "strerror_r" to return an "int", some systems
(e.g. the GNU libc) return a "char *" _and_ ignore the second argument (user
provided buffer). The configure script now checks for that behavior using
AC_FUNC_STRERROR_R. rrd_strerror() in rrd_thread_safe.c has been updated to
(hopefully) handle all possible cases.

Previously, rrd_strerror() would have returned "strerror_r failed. sorry!" in
mostly any cases when using glibc, since "if (strerror_r())" had been used to
check for errors which evaluates to true if a (non-NULL) pointer was returned.

Now, we, at least, return the error number in case anything else fails.

Thanks to Alessandro Iurlano for reporting this issue after spotting it in
collectd <http://collectd.org>.

Attached a patch for the rrd-tool LIBDBI integration with the following improvements:

a) correct error handling in case of libdbi being unable to load the driver
   was producing segmentation faults.

b) better parsing of datasources

   * until now timestamp fields had to be integer and had to contain a unix
     timestamp - now you can now also use DateTime fields (you still need to
     specify it, as the time-range needs to be defined correctly)

   * data fields are now no longer limited to (var)char or DOUBLE fields -
     FLOAT, INTEGER,... are now also supported.

c) there is a bug with at least LIBDBI 0.8.1 in conjunction with mysql that
   can result in segmentation faults when BINARY/BLOB fields are accessed -
   rrdtool will now tell you about this fact before dying ;)

d) also the value of rrdderivemaxstep only gets applied if derive has been
   selected correctly.

e) "GROUP BY timestamp" has been removed from SQL statement.

f) "ORDER BY timestamp" will be added only in the case of fetching "derived" data.

This patch allows for multiple RRD writer threads to service the queue.

Now, rrdcached can have more simultaneous I/O requests into the kernel.
This may allow the kernel to re-order disk writes, resulting in better
disk throughput. In practice, throughput is increased by 2-3x.

The flush (-f) timer maintenance has been moved from queue_thread_main
into its own thread.

Be more careful about when to use pthread_cond_signal vs _broadcast, since
multiple threads may be waiting on &queue_cond.

rrdcached now frees all of its resources correctly.  This facilitates

them.

Also, use g_tree_replace instead of g_tree_insert.  This fixes a bug
