14 test cases use _test_generic_punch(), and they work well as long
as the ext4/xfs blocksize or btrfs sectorsize is below 4K.
In the system with 64K pagesize, as the blocksize can be upto 64K or the
sectorsize can be 64K so 13/14 test cases fail, because the
test-file-size (20k) and thus the extent boundary offsets aren't
big enough to fit the larger than 4k extent size.
Commit 2f194e4e82 (generic/009: don't run
for btrfs if PAGE_SIZE > 4096) tried to address this by calling the
not_run in generic/009.
And in the function _test_generic_punch() we use multiple=4 to address
the similar problem but its limited to the subcommand fcollapse.
Now to run these test cases successfully on systems with pagesize 64k,
this patch propose to increase the default multiple=1 to multiple=16.
With this we increase the test file size from 20k to 320k and thus it
encapsulates maximum extent size of 64k here. And we can drop the
multiple=4 which is just being done similar for the cases of fcollapse
subcommand only. And it appears to me there is no harm in increasing
the file size and offsets in general for all commands instead of just
fcollapse command.
This change is tested on ext4, xfs and btrfs on system with pagesize
4K and 64K.
With this patch, these 14 test cases runs fine on system with 64K
pagesize as well as pagesize 4K. However we may hit the same
limitation at some point when we want to validate the FSs with
pagesizes -gt 64K. And this patch does not address that part as of
now.

The first test may start with the file from the previous test, and
that is in an unknown state. Hence always remove the test file
before the first test so that it doesn't have extents inside the
test range as it is supposed to be testing into a hole.

Test 17 of _test_generic_punch uses the filesystem block size to do
a sub-single block punch. The result of this is a files of
different sizes and md5sums when the filesystem block size changes.
However the only difference in file contents if the length of the
file - the zeroed region is always in the same place. Hence we can
use hexdump rather than md5sum to check the output remains
consistent and the hole remains in the correct place despite the
changing block sizes.
Fix up all the golden output for all the tests that use this
function, too.

After applied this commit (864688d3), xfstests #255 will not test a
file system that cannot support fallocate(2), such as a indirect-based
file in ext4. So we need to add a new generic test case to test it.
The difference between #255 and this test case is only to use pwrite to
allocate blocks. Other filesystems should survive in this test case.
In the mean time, a new argument '-u' is added into _test_generic_punch
not to run unwritten tests.
