Before only one comparison was allowed. Let's make this more flexible:
ConditionKernelVersion = ">=4.0" "<=4.5"
Fixes#12881.
This also fixes expressions like "ConditionKernelVersion=>" which would
evaluate as true.
It is pretty hard to figure out what the problem actually is, esp. when the rule
is long.

Whenever I see EXTRACT_QUOTES, I'm always confused whether it means to
leave the quotes in or to take them out. Let's say "unquote", like we
say "cunescape".
This reverts a part of commit 49fe5c0996 ('tree-wide: port various places
over to STARTSWITH_SET()') that replaced a pair of startswith() calls
with STARTSWITH_SET().
They were in fact for a different strings (device vs. name), botching
the crypttap parsing.
Previous code was allocating an array of iovecs big enough to store all the
fields added later by various functions.
This forced us to calculate the size of the array in advance which is too error
prone if for example one wants to add new fields or simply rework the
code. Various assertions were added to make sure there's no overflow but it's
still more code for no good reasons.
Instead, this patch switches to the new iovec array handling interface so the
array is grown dynamically when needed.
The other contraint was that some iovecs were supposed to be freed whereas some
others were not. This makes the code hard to (re)organize. The new code always
allocates fields so it becomes easier to rework the code.
We'd skip any whitespace immediately after "=", but then we'd treat whitespace
that is between "|" or "!" and the value as significant. This is rather
confusing, let's ignore it too.
If hibernation is requested but /sys/power/resume and
/sys/power/resume_offset are not configured correctly, systemd-sleep
attempts to calculate swapfile offset using fstat and fiemap.
Btrfs returns virtual device number for stat and a virtual offset
for fiemap which results in incorrect offset calculations. In the
case where offset would be calculated and the user is using Btrfs,
log a debug message and fail to write device and offset values.
Use hibernation configuration as defined in
/sys/power/resume and /sys/power/resume_offset
if present before inspecting /proc/swaps and
attempting to calculate swapfile offset
