rrdcached: add options to drop privileges after daemonize
Some init systems have an interface to run daemons as unprivileged
accounts, but they conflict with rrdcached's expectations of creating
pid files and sockets in privileged areas when following Filesystem
Hierarchy Standard namings. Add options that are used to drop to
unprivileged group and accounts after all activities that require
privilege have been completed.

rrdcached: arrange option flags in order
To make it easier to determine which argument flags are available, the
getopt optstring is sorted into ASCII order. Checking this against the
documentation indicated several supported flags were not present in the
synopsis. Also make all flags bold for consistency.

rrdcached: support new option to listen on all addresses at default port
This functionality can be achieved with "-l ''" (specifying an empty
string for host:port) but empty strings may be dropped during option
processing in scripts. A separate option to support this capability is
much more clear.

misc doc: fix erronous use of section qualifier in intra-package links
rrdxport and rrdcached do belong in section 1 of the Unix manpages, but
they are documented within the RRDTool hierarchy and use of the
qualifier prevents them from being found. Note also the need to
override the substitute text or modify the context so that the generated
HTML content reads correctly.

rrd_daemon: move include of arpa/inet.h to avoid use on Windows
arpa/inet.h may not be available on Windows systems; since I can't test
that, avoid trying to include it there. Since the code that depends on
it is conditional on a define that would be provided by it, there should
be no impact from its absence except that somebody who uses Windows
would have to rework the fix for ipv4-over-ipv6 for that platform.

added PREDICTPERC function
there is one still open question: should we interpolate to get the final value?
Say: if we have 8 values, and we want thd 95th percventile, then
we should actually take the 6.65th 0-based index value (=95/100*(8-1)).
with the current implementation we round, so we return actually the 100th percentile.
what we could also do is:
value=val[floor(idx)]+(idx-floor(idx))*(val[floor(idx)+1]-val[floor(idx)])
