[PATCH 0/3 V4] e2fsprogs/debugfs: do sparse copy when src is a sparse file

[Robert Yang <liezhi.yang@windriver.com>]

=== V4:
* Add a free(buf) in debugfs.c to fix a potential memory leak issue.

* Add the contrib/populate-extfs.sh to populate the ext2/3/4 filesystem
  from a given directory.

=== V3: 
* Use BUFSIZ (which is 8192 on Linux systems) for the max argument
  length as Ted suggested.

* Use ext2fs_get_memzero() and move it out of the while loop to get a
  better performance as Darrick suggested.

=== V2: 
* Use 64K for the IO_BUFSIZE and use malloc() to allocate the memory for 
  the buffer respect to Darrick's comments.

* Use calloc() and memcmp() to check the sparse block as Darrick
  suggested.

* Adjust the frame and remove a few un-needed code as Darrick
  suggested.

=== V1: 
* There are two patches, one is used for fixing the max length of the 
  argument, the other one is for sparsing copy when src is a sparse
  file.

  debugfs.c: the max length of debugfs argument is too short
