Test several scenarios for RWF_NOWAIT writes, to verify we don't regress
on btrfs specific behaviour (snapshots, cow files, reflinks, holes,
prealloc extent beyond eof).
We had some bugs in the past related to RWF_NOWAIT writes not failing on
btrfs when they should or failing when they shouldn't, these were fixed by
the following kernel commits:
4b1946284dd6 ("btrfs: fix failure of RWF_NOWAIT write into prealloc extent beyond eof")
260a63395f90 ("btrfs: fix RWF_NOWAIT write not failling when we need to cow")

Starting with version 2.41 of libcap, the output of the getcap program
changed and therefore some existing tests fail when the installed version
of libcap is >= 2.41 (the latest version available at the moment is 2.44).
The change was made by the following commit of libcap:
commit 177cd418031b1acfcf73fe3b1af9f3279828681c

A more compact form for the text representation of capabilities.
While this does not change anything about the supported range of
equivalent text specifications for capabilities, as accepted by
cap_from_text(), this does alter the preferred output format of
cap_to_text() to be two characters shorter in most cases. That is,
what used to be summarized as:
"= cap_foo+..."
is now converted to the equivalent text:
"cap_foo=..."
which is also more intuitive.
So add a filter to change the old format to the new one, an helper that
calls getcap with that filter, make existing tests use the new helper and
update their golden output to match the new output format of getcap.

This test essentially creates an existing COW extent which
covers the first 1M, and then does another IO that overlaps it,
but extends beyond it. The bug was that we did not trim the
new IO to the end of the existing COW extent, and so the IO
extended past the COW blocks and corrupted the reflinked files(s).
The bug came and went upstream. It was introduced by:
78f0cc9d55cb "xfs: don't use delalloc extents for COW on files with extsize hints"
and (inadvertently) fixed as of:
36adcbace24e "xfs: fill out the srcmap in iomap_begin"

In Linux v5.6, f2fs added support for per-file compression. f2fs
compression can be used in combination with the existing f2fs encryption
support (a.k.a. fscrypt), in which case the compressed data is encrypted
rather than the uncompressed data.
We need to verify that the encryption is actually being done as expected
in this case. So add a test which verifies it.
For now this is a f2fs-specific test. It's possible that ext4 will
implement compression in the same way as f2fs (in which case this could
be made a generic test), but for now there are no plans for that.
This complements the existing ciphertext verification tests, e.g.
generic/548, which don't handle compression. Encryption+compression has
some unique considerations, so it requires its own test.

Currently fscrypt-crypt-util assumes that the number of the first block
encrypted/decrypted is 0. I.e., it replicates either contents
encryption from the start of a file, or encryption of a filename.
However, to easily test compression+encryption on f2fs, we need the
ability to specify a different starting block number.
Add a --block-number option which does this.

fscrypt-crypt-util treats the "block number" part of the IV as 64-bit
when incrementing it. That's wrong for --iv-ino-lblk-32 and
--iv-ino-lblk-64, as in those cases the block number should be 32-bit.
Fix this by using the correct length for the block number.
For --iv-ino-lblk-64 this doesn't actually matter, since in that case
the block number starts at 0 and never exceeds UINT32_MAX.
But for --iv-ino-lblk-32, the hashed inode number gets added to the
original block number to produce the IV block number, which can later
wrap around from UINT32_MAX to 0. As a result, this change fixes
generic/602, though since the wraparound case isn't specifically tested
currently, the chance of failure was extremely small.

1) If underlying filesystem is ext4, the lower overlay inodes do not
have the MSB set (e.g. file ino 8590721028 = 0x2000C0004) because
ext4 has a known inode number limit of 32bit (see ovl_can_decode_fh).
2) With nested xino feature, the nested overlay inodes have the MSB set
(e.g. file ino 9223372045445496836 = 0x80000002000C0004).
It is expected different inode numbers which casue the failure of
overlay/071, so fix this failure by removing the unneeded comparision.
