Namjae Jeon f1dcf49c11 shared/005: Test multiple fallocate collapse
We execute collapse range multiple times on same file.  Each
collapse range call collapses a single alternate block.  After the
test execution, file will be left with 80 blocks and as much number
of extents.  We also check for file system consistency after the
completion.

# Test multiple fallocate collapse range calls on same file.
# For different blocksizes, collapse a single alternate block multiple times
# until the file is left with 80 blocks and as much number of extents.
# Also check for file system consistency after completing this operation
# for each blocksize.
