* Add names to the parameters and write documentation for the only exported

configure.ac: make finding java deterministic
The sort order of the `find` command proves to be dependent on external
factors, which makes `./configure` pick different java versions on
different systems, making the whole build non-reproducible (see
https://reproducible-builds.org/ for more details).
Adding a call to `sort`, with the locale forced, fixes this issue.

RRDCacheD plugin: Try to reconnect upon failed operations.
The RRD client library does not provide means to check the status of a
connection and there's no way to detect that the connection is broken after,
for example, the daemon restarted. To work around that, try to reconnect if
any client operation fails.
Assume, for example, the config `Key "*/foo"`. This config expects JSON
in the form:
{
"bar": {
"foo": 1337
}
}
If the available JSON is instead:
{
"error_code": 0,
"bar": {
"foo": 1337
}
}
the code will take a look at the zero associated with "error_code" and
determine that a map (with key "foo") is expected instead. Previously
the code would continue, eventually calling `cj_get_type()` which
expects that `key->type` is a valid pointer, resulting in a segmentation
fault.
This patch does three things to ensure that this segmentation fault does
not happen again:
1. `cj_get_type()` checks its argument to make sure it is valid before
dereferencing any pointers.
2. In case a non-map is found when a map is expected, the code will
return instead of limping on.
3. After calling `cj_cb_inc_array_index()`, which may update the key,
make sure that it actually did and that key is valid now.
network plugin: Initialize libgcrypt only when needed.
Previously, libgcrypt was initialized unconditionally in network_init(),
which may cause trouble on some systems. With this patch, gcrypt is
initialized if:
* A client socket as signing or encryption enabled, or
* a server socket has an auth_file configured.

Fix conceptual buglet in default_callback
The 'DERIVE' path in default_callback() increments the 'counter' field of
value instead of the 'derive' field. Since those fields have the same
type and offset within the value union this will still work fine, but
AFAICT it's conceptually incorrect. This corrects it.

network plugin: Fix heap overflow in parse_packet().
Emilien Gaspar has identified a heap overflow in parse_packet(), the
function used by the network plugin to parse incoming network packets.
This is a vulnerability in collectd, though the scope is not clear at
this point. At the very least specially crafted network packets can be
used to crash the daemon. We can't rule out a potential remote code
execution though.

librrd 1.6.0 is now threadsafe and librrd_th is gone.
Since there doesn't seem to be a way to detect that librrd
is threadsafe, use pkg-config to check for 1.6.0 or newer instead.
The logic is now as follows:
Check for librrd >= 1.6.0 with pkg-config
If not found, look for rrd_update_r in librrd_th.
If not found, look for rrd_update in librrd and assume librrd is not
thread safe.
