* add list of supported aliases to 'l' and 'L' output
* support aliases in 't' dialog
For example (use 'swap' to set 0x82 partition type):
Command (m for help): t
Selected partition 1
Hex code or alias (type L to list all): swap
Changed type of partition 'Linux' to 'Linux swap / Solaris'.
Note that the aliases are evaluated as the last possibility if user's
input dues not match up with any partition type. This is necessary for
backward compatibility.
This patch does NOT introduce shortcuts (.e.g. 'S' for swap) to
fdisk(8) due to collisions with already used dialog keys.

* add support for aliases to sfdisk scripts
* add shortcuts and aliases to --part-type command
Note that --part-type evaluates shortcuts and aliases as the last
possibility (so after regular type string). This is necessary for
backward compatibility.
Example ('raid' type alias):
# sfdisk --part-type /dev/sdc 1 raid
# fdisk -l /dev/sdc
...
Device Boot Start End Sectors Size Id Type
/dev/sdc1 2048 204799 202752 99M fd Linux raid autodetect
Example ('L' type shortcut):
# sfdisk --part-type /dev/sdc 1 L
# fdisk -l /dev/sdc
...
Device Boot Start End Sectors Size Id Type
/dev/sdc1 2048 204799 202752 99M 83 Linux

Now, the type shortcuts are supported for sfdisk scripts only.
Unfortunately, the current implementation is not generic enough
and it's also fragile as 'E' shortcut is in collision with 0x0E
type for MBR. The another issue is 'L' which makes shortcuts useless
for fdisk where 'L' is used for another purpose in dialogs.
This patch introduces partition type aliases as extension to
shortcuts. The definition of the shortcut is part of the label
definition and it's not more hardcoded in sfdisk script code.
This patch also introduces 'Ex' shortcut as replacement for (now
deprecated) 'E'.

The classic mount(8) behavior is to try read-only on write-protected devices
if the first mount syscall attempt ends with EACCES.
It seems we can implement this feature also for EBUSY if the same mount source
is already mounted with "ro" superblock option.
The typical use-case is iso image (always read-only) mounted on two places.

- use fdisk_is_partition_used() as fdisk_get_partition() returns
nothing for unused partition
- update tests
- add more hints to the man page

sfdisk trying to be more smart than libfdisk when analyze if we can
append to the current PT. libfdisk is able to use unused partition
to create a new one (if partno not strictly specified), but sfdisk
assumes that we can add partition to extended partition only.

Since v2.34 --list prints devices only once to make the output
user-readable. Unfortunately, it's regression for scripts/applications
where we need to parse lsblk output. So, let's make --pairs and --raw
backwardly compatible with versions before 2.34 and print all hierarchy.

Let's consolidate the code, we need to use it in libfdisk too. It
seems better to keep it generic and libblkid independent.
This patch also removes blkid_encode_alloc(), this function is overkill.

GNU C Library NEWS -- history of user-visible changes.
Version 2.31
Deprecated and removed features, and other changes affecting compatibility:
* The settimeofday function can still be used to set a system-wide time
zone when the operating system supports it. This is because the Linux
kernel reused the API, on some architectures, to describe a system-wide
time-zone-like offset between the software clock maintained by the kernel,
and the "RTC" clock that keeps time when the system is shut down.
However, to reduce the odds of this offset being set by accident,
settimeofday can no longer be used to set the time and the offset
simultaneously. If both of its two arguments are non-null, the call
will fail (setting errno to EINVAL).
Callers attempting to set this offset should also be prepared for the call
to fail and set errno to ENOSYS; this already happens on the Hurd and on
some Linux architectures. The Linux kernel maintainers are discussing a
more principled replacement for the reused API. After a replacement
becomes available, we will change settimeofday to fail with ENOSYS on all
platforms when its 'tzp' argument is not a null pointer.
settimeofday itself is obsolescent according to POSIX. Programs that set
the system time should use clock_settime and/or the adjtime family of
functions instead. We may cease to make settimeofday available to newly
linked binaries after there is a replacement for Linux's time-zone-like
offset API.
______________________________________________________
hwclock(8) had one settimeofday(2) call where both args were set for
--hctosys when the RTC was ticking UTC. This allowed setting the system
time, timezone, and locking the warp_clock function with a single call.
That operation now takes 3 calls of settimeofday(2).
Although this common operation now takes three calls, the overall logic
for the set_system_clock() function was simplified.

Allocating and freeing all the time is a little bit heavier, but it is also
more robust. It is impossible to know if field lenghts stay fixed.

This commit add total and delta as separate columns rather than a toggle,
making output generally more informative. When using command I found that
sort order key bindings should match with first letter of column headers so
that they are as easy as possible to remember, and therefore enhancing user
experience.

This matches with sort order n for name, and allows later usage of d for
delta without needing to go around d for description.

The event loop takes care of the standard screen updates, signals, and user

With very short delay one can see irqfile file descriptors pile up rather
quickly causing program to stop with too many open files error. This commit
fixes that, and removes couple other memory leaks. With these the command
should hopefully run fine for days if not even months.

currently, there are usually 40/48/64/96 CPUs on a single server,
and a lot of interrupts are enabled by multi-queues of a NIC.
"/proc/interrupts" is not human readable any more.
'watch -d -n 1 "cat /proc/interrupts"' also can not work well.
so implement irqtop to show the interrupts information, we can
sort the interrupts by count(default), name and /proc/interrupts.
