Add extable autotest while initialization
Add kernel text segment limits finder
Add LSM security_ops find method implementation
Add LSM security_ops cross-reference scanner

This adds an example of how to dealt with LSM hooks while scanning
kernel's memory for the patterns. We'll try to find all the xrefs to
security_ops that looks like:

    security_ops->inode_permission(...)

So, to solve this task we scan all the kernel's text memory for the
patterns and then analyze such entries for the 'call ...' command.
