[Ocfs2-tools-devel] The ocfs2 configure file vertify tool, second modification.

[Xiaowei Hu]

1. Fixed a bug. When there is more than 255 entries in the
configure file there will be error messages like this:
./o2cb_verify.sh: line 263: ((: IP_address < 1024: syntax error in   
expression (error token is "part of ip address < 1024")

2. Changed the warning message,use "Please check this" instead of 
"Invalid".

3. Cleaned all end of line whitespaces.

4. When you run with a cluster.conf having 100 nodes, you will notice
that it takes a long time for the first feedback to appear. Now some
progress showed. 

5. Removed unnecessary messages like the following.For this information
you can use -v option now. 

The node whose ip address is ca-test96 is invalid.[SKIPED]

6. -o filename option is available now,it can dump the final output 
to a file. 

7. -s option is available now,that limits the checking to just pure 
syntax.Without ssh connection test.
