Timo Tijhof 456a3b1009 lockmanager: Clean up file headers and @ingroup
Follows similar commits to the objectcache, rdbms, profiler,
filerepo components and other areas [1].

* Remove duplicate descriptions from file blocks in favour of class
  doc blocks. This reduces needless duplication and was often
  incorrect or outdated, and helps (ironically) to make the file header
  more consistently visually ignorable.

* Remove `ingroup` from file blocks in class files as otherwise
  the file is indexed twice (e.g. in Doxygen) which makes navigation
  more messy.

* Remove use of AtEase.
