The following changes have been checked into napali:

1. The is some template voodoo in KM_fileio.h to ward off the D_FILE_OFFSET_BITS=64 bug
2. KM_log.cpp now uses mutex protection for the global default LogSink
3. I added Kumu::Version (uses the same value as ASDCP::Version()). I did this because...
4. I modified Makefile.am so that  kmfilegen, kmrandgen, and kmuuidgen only link against libkumu, as nature intended.
