Subject: [PATCH] Do not include symlink_state in 5.10 content
The symlink_test, object and state were added in OVAL 5.11. These
elements should not be included in OVAL 5.10 content because they break
validation.

Subject: [PATCH] Restrict the symlink test to OVAL 5.11
The symlink_test was added in OVAL 5.11 and is not availble in 5.10.
The 5.10 version of the sysctl template will not check for sysctl
options defined in more than on file.

Subject: [PATCH 1/3] Add tests to ensure valid symlinks are checked
These sysctl tests help check cases when:
- A symlink points to a file out of the default default dirs
- Multile symlinks point to the same file in the default dirs
Symlinks are a valid use case how to configure sysctls.

Subject: [PATCH 2/3] Filter out symlinks referencing default dirs
Apply a filter on the collected symlinks and exclude the ones that
don't point to the default dirs.
In other words, only remove ignore options in symlinks if the files they
reference will be scanned anyway, because they are in the one of the
default dirs.

Subject: [PATCH] Don't scan dir with preconfigured sysctls in RHEL
With the introduction of checks for options defined in multiple
files
the pre-configured sysctls became prominent and started to cause
rules
to fail.
In /usr/lib/sysctl.d there are sysctl options defined by systemd and
other packages. The files in witch these options are defined are not
meant to be edited, these options should be overriden by options in
dirs of higher priorrity, like /etc/sysctl.d, or /etc/sysctl.conf.
Remediating these files will cause problems with rule
rpm_verify_hashes,
as these files are not RPM config files.
As the sysctl remediations don't edit the pre-configured files the
rule will always result in error.
This commit removes the checks for the pre-configured directory,
i.e. /usr/lib/sysctl.d/.
The end result is that any sysctl option that is pre-configured in
/usr/lib/sysctl.d will be defined in two files, the pre-configured
one
ane /etc/sysctl.conf.
The sysctl option in effect should be the one configured in
/etc/sysctl.conf as this file has the highest priority for sysctl.

This avoids directly referencing a variable that may have no values.
If no symlinks are found, 'local_var_symlinks_{{{ SYSCTLID }}}' will
have "no values".
Using this variable in the state comparison will automatically cause the
definition to evaluate to "unknown".
What we do here is inject a blank string with the use of <set>, this
way, when no symlinks are found, the variable has a single blank string.
