[svn-r1929] Added the srcdir option to support concurrent tests by different
hosts. Below is the help output for srcdir.
srcdir: Use srcdir option (does not imply other commands)"
"snapshot srcdir" is equivalent to "snapshot srcdir all"
"snapshot srcdir checkout" is equivalent to "snapshot checkout"
Also used shell variables to hold directory paths for easier maintenance.
