This patch adds a new implementation of locking function instead of mlockall() that may lock way too much memory (>100MB). New function instead uses mlock() system call and selectively locks memory areas from /proc/self/maps trying to avoid locking areas unused during lock-ed state. Patch also adds struct cmd_context to all memlock() calls to have access to configuration. For backward compatibility functionality of mlockall() is preserved with "activation/use_mlockall" flag. As a simple check, locking and unlocking counts the amount of memory and compares whether values are matching.
