clone for rhel5

+++ This bug was initially created as a clone of Bug #962394 +++

Description of problem:
Please, update xfs_io man page to include documentation for the following commands:
chproj
lsproj
setfl

Version-Release number of selected component (if applicable):
xfsprogs-3.1.1-10.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Run xfstests test no. 293 that checks for this behaviour.
2.
3.
  
Actual results:
The test fails reporting the missing documentation for the threee commands.

Expected results:
The commands are documented.

Additional info:
The test case seems to be written by Eric Sandeen. Hence, I searched the bugzilla for a similar report. However, I didn't find any RHEL 6 report for this lack of documentation.

xfs_io -c help already provides basic documentation for the three commands:

chproj [-D | -R] projid -- change project identifier on the currently open file
lsproj [-D | -R] -- list project identifier set on the currently open file
setfl [-adx] -- set/clear append/direct flags on the open file

    xfsprogs: document all commands in xfs_io
    
    Add missing command documentation to xfs_io(8) manpage.
    fiemap, fpunch, chproj, lsproj, and setfl are all missing.
    
    setfl seems to not work today in any case, and nothing
    in xfstests uses it; I will send another patch to simply
    remove it from xfs_io, as I don't think it's terribly useful,
    and hasn't worked forever anyway.
    
    Also fix references to the fallocate manpage, which is (now?)
    in section 2, not section 3 of the man pages.  (Since it's
    a syscall, not a library function).

    xfsprogs: remove setfl from xfs_io
    
    Doesn't seem to have worked for ages, and is (therefore)
    apparently not ever used:
    
    xfs_io> setfl
    xfs_io> help setfl
    setfl [-adx] -- set/clear append/direct flags on the open file
    xfs_io> setfl -a
    bad argument count 1 to setfl, expected 0 arguments
    xfs_io> setfl -d
    bad argument count 1 to setfl, expected 0 arguments
    xfs_io> setfl
    xfs_io>
    
    At best, it seems intended to toggle the flag state, but
    gives no feedback about current state.  -x is in help but
    not implemented, etc.
    
    Just remove it.

If we are allowed to update xfsprogs in 6.5 it'd be easy to include these 2 commits.
