Disk space monitoring

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)
