lsfd: revise the code disabling hyperlinks
In the original code, the code was at file.c. This change lifts up
the code to upper layer. As a result the fill_column method of struct
file becomes simple.
As a side effect. this change disables hyperlinks for the entries of
UNKN type (e.g. eventpool, or pidfd). This is a bug fix.

zramctl: ignore ENOENT when setting max_comp_streams
The `max_comp_streams` attribute of zram devices has been deprecated and
all writes were silently ignored by the kernel since 2016. It was
finally removed in 6.15, causing zramctl to fail on ENOENT, when it
should just ignore the error.

Add reflink support for ZFS.
OpenZFS has added the block cloning feature, which implements reflinks for its copy-on-write filesystem. It is now stable and enabled by default on OpenZFS 2.3.0.
This feature addition will add the '-U' and '--unknown' options
It'll allow getopt to ignore unknown options and leave them untouched.
Additionally, it will surpress any error messages generated by getopt(3).

zramctl: fix MEM-USED column description
The MEM-USED column was incorrectly documented as showing current
memory consumption. This is due to confusing naming in the kernel's
zram implementation:
- Kernel field "mem_used_total" (3rd in mm_stat) = current memory usage
- Kernel field "mem_used_max" (5th in mm_stat) = peak memory usage
zramctl maps these as:
- TOTAL column <= mem_used_total (current usage)
- MEM-USED column <= mem_used_max (peak usage)
The misleading "MEM-USED" name suggests current usage, but it actually
shows the peak memory usage (high water mark) since device creation
or last reset. This is tracked by the kernel's max_used_pages which
only increases when current usage exceeds the stored maximum.
Fixed description from:
"memory zram have been consumed to store compressed data" to
"peak memory usage to store compressed data".
