Changes of V2:
* Rebase the code to the up to date master branch

Here are the test info:
1) set the following variables in conf/local.conf for testing:
   BB_DISKMON_DIRS = "${TMPDIR} ${DL_DIR} ${SSTATE_DIR} /home/lyang1"
   BB_DISKMON_MINSPACE = "200G"
   BB_DISKMON_MININODES = "20M"
   BB_DISKMON_INTERVAL = "30s"

   The TMPDIR, DL_DIR and SSTATE_DIR are in the same disk(/dev/sdb4) in
   my build, so I added another direcotory /home/lyang1 to test the
   ability of monitoring multi mount points.

2) bitbake core-image-sato
   WARNING: The free space of /dev/sdb5 is running low (25.915GB left)
   WARNING: The free inode of /dev/sdb5 is running low (1788.202K left)
   WARNING: The free space of /dev/sdb4 is running low (189.309GB left)
   WARNING: The free inode of /dev/sdb4 is running low (18005.443K left)

3) Aalso have tested about the following items:
   a) Use ctrl-c to stop the monitor
   b) The monitor should stop when the build stops
   c) Test the space unit G, B, K(case in-sensitive) and the time unit
      h, m, s(case-sensitive)

I would think it'd be more useful to be able to specify the thresholds
on a per-mountpoint or per-path basis. The space needed by sstate,
downloads, and the rest of the build can be quite different. Further,
the space requirements for DL_DIR and sstate both are dependent upon
the current contents of the directories, as if we already have all our
downloads, the free space there isn't much of a concern..
