If the ruleset source has been changed, it has to be configured again.
This happens because of different rule categories, filenames rule ID's etc.
In case suricata currently is running it has to be stopped and after the configuration
has been done by the user, it can be launched again.

This function is used to write the corresponding file which
tells oinkmaster to alter the whole ruleset and finally
switches suricata into an IPS or IDS.

Now each of both have their own corresponding configuration areas.
The taken settings will be saved in "/var/ipfire/suricata/settings" for
all IDS/IPS related settings and in "/var/ipfire/suricata/rules-settings" for
ruleset related settings.

Currently, the wget call only uses proxy information for HTTP.
Since rulesets are downloaded via HTTPS now, the same information
also needs to be applied for HTTPS.

Only set the state of a used rulefile to "on" if it is present in
the %idsrules hash. This happens if it contains at least one rule.
This prevents from showing a rulefile in the ruleset section if, it
does not exist anymore or does not contains any rules at all.

Create this file on first execution of the script if it does not exist yet.
This will allow suricata to imediately be started. Otherwise the ruleset has
to be downloaded and configured before this file has been created and suricata
could be launched.

Now the enabled or disabled sids are stored in a single
hash instead of two arrays, which easily can be modified.
When saving the ruleset, the new read_enabled_disabled_sids() function
will be used to read-in the current (old) saved enabled or disabled sids
and add them to the new hash structure.
After adding or modifiying sids to the hash, the entries will be written
to the corresponding files.

This commit adds the required backend code to allow switching
between IDS and IPS mode of suricata.
Technically the behaviour of suricata is specified by the rules -
each of them can contain the action "alert" or "drop" (There are
more actions supported but these two are currently the important one)
When running in IDS mode, the ruleset does not need to be touched,
because the default action is "alert". When switching to IPS mode,
the CGI writes a single line to "oinkmaster-modify-sids.conf" which
is included by oinkmaster and modify the action for each single rule
from alert to drop.

The Emerging Threats ruleset server supports HTTPS. It should
be used for downloading the ruleset in IPFire, too.
This also needs to be applied on the upcoming ids.cgi file for Suricata
which I will do in a second patch.
The third version of this patch superseds the first and
second one which were broken due to bugs in the MUAs GPG
implementation.
