taskstats is only checked on runtime if the column RCHAR, WCHAR, SYSCR,

If currently two unsigned values are compared via `a - b`, in the case b
is actually bigger than a, the result will not be an negative number (as
-1 is expected) but a huge positive number as the subtraction is an
unsigned subtraction.
Avoid over-/underflow affected operations; use comparisons.
Modern compilers will generate sane code, like:
xor eax, eax
cmp rdi, rsi
seta al
sbb eax, 0

Axe automated header generation.
...
Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.

Promote the Arg union to a core data type in Object.c such
that it is visible everywhere (many source files need it),
and correct declarations of several functions that use it.
The Process_sendSignal function is also corrected to have
the expected return type (bool, not void) - an error being
masked by ignoring this not-quite-harmless warning. I've
also added error checking to the kill(2) call here, which
was previously overlooked / missing (?).

Add support for Linux TASK_IDLE
...
Linux commit 06eb61844d841d0032a9950ce7f8e783ee49c0d0 ("sched/debug:
Add explicit TASK_IDLE printing") exposes kthreads idling using
TASK_IDLE in procfs as "I (idle)".
Until now, when sorting the STATE ("S") column, htop used the raw
value of the state character for comparison, however that led to the
undesirable effect of TASK_IDLE ('I') tasks being sorted above tasks
that were running ('R').
Thus, explicitly recognize the idle process state, and sort it below
others.

Adds support for linux delay accounting ( #667 )
...
Adds support for showing columns with linux delay accounting.
This information can be read from the netlink interface, and thus we set up a socket to read from that when initializing the LinuxProcessList (LinuxProcessList_initNetlinkSocket). After that, for each process we call LinuxProcessList_readDelayAcctData, which sends a message thru the socket after setting up a callback to get the answer from the Kernel. That callback sets the process total delay time attribute. We then set the delay percent as the percentage of time process cpu time since last scan.
