* Remove calls to rrdset_next().
* Rm checks plugin
* Update documentantion
* Call rrdset_next from within rrdset_done
This wraps up the removal of rrdset_next from internal collectors, which
removes a lot of unecessary code and the need for if/else clauses in
every place.
The pluginsd parser is the only component that calls rrdset_next*()
functions because it's not strictly speaking a collector but more of a
collector manager/proxy.
With the current changes it's possible to simplify the API we expose
from RRD significantly, but this will be follow-up work in the future.
* Remove stale reference to checks.plugin
* Fix RRD unit test
rrdset_next is not meant to be called from these tests.
* Fix db engine unit test.
* Schedule rrdset_next when we have completed at least one collection.
* Mark chart creation clauses as unlikely.
* Add missing brace to fix FreeBSD plugin.
|

* fix kickstart message
* workaround for agent UI

By default functions are declared as extern in C/C++ headers. The goal
of this PR is to reduce the wall of text that many headers have and,
more importantly, to make the declaration of extern'd variables - of
which we have many dispersed in various places - easily and quickly
identifiable.
Automatically generated with:
$ git grep -l '^extern.*(' '**.h' | \
grep -v libjudy | \
grep -v 'sqlite3.h' | \
xargs sed -i -e 's/extern \(.*(.*$\)/\1/'
This is a NFC.

Currently, we add the repository's top-level dir in the compiler's
header search path. This means that code in every top-level directory
within the repo can include headers sibling top-level directories.
This patch makes header inclusion consistent when it comes to files
that are included from sibling top-level directories within the repo.

Before:
```
struct foobar {
avl avl;
...
}
```
After:
```
struct foobar {
avl_t avl;
...
};
```
Which makes figuring out the type from field name easier.

The default cloud url has been updated to app.netdata.cloud ready for the release. The claiming process now checks the current user executing claiming and refuses to perform the claim for the wrong user. If the current UID is 0 then claiming proceeds but the file ownership is adjusted to be the correct netdata user. The default expected user is `netdata` unless the script can identify the user from the current configuration. After the claiming script is executed the CLI is used to reload the claiming state.

Our default configuration includes:
allow connections from = localhost *
allow management from = localhost
The problem occurs when a connection is received that passes the `allow connections` pattern
match, but fails the ACL check for `allow management`. During the failure processing path the
DNS lookup is triggered to allow the FQDN to be checked against the pattern. On a FreeBSD
system this lookup fails more slowly than linux and causes a visible performance problem
during stress-testing.
The fix adds a heuristic to analyse the patterns and determine if it is possible to match a DNS name,
or only match a numeric IP address (either IPv4 or IPv6), or only match a constant value. This
heuristic is used to disable the DNS checks when they cannot produce anything that may match
the pattern. Each heuristic is evaluated once, when the configuration is loaded, not per-connection to the agent.
Because the heuristic is not exact it can be overridden using the new config options for each of the ACL connection filters to set it to "yes", "no" or "heuristic". The default for everything *except* the netdata.conf ACL is "heuristic". Because of the numeric-patterns in the netdata.conf ACL the default is set to "no".
