o Dynamically load all the .so files found in /libexec/nvmecontrol and
o Link nvmecontrol -rdynamic so that its symbols are visible to the
libraries we load.
o Create mirrored linker sets that we dynamically expand.
o Add the linked-in top and logpage linker sets to the mirrors for them
and add those sets to the mirrors when we load a new .so.
o Add some macros to help hide the names of the linker sets.
o Update the man page.
