Searching man systemd(1) for "is-system-running" we see these states:
initializing
starting
running
degraded
maintenance
stopping
offline
unknown
Let's differentiate some more: green (ok) if state is "running", red (error)
if the state is unknown to htop or "degraded", yellow (warning) for
everything else (incl. "initializing", "starting", "maintenance" &
"stopping").

In the situation where the currently displayed screen is
removed we could end up with an invalid ss pointer (and
associated index) in the global Settings structure. Any
subsequent access to these fields would make an invalid
pointer dereference.
Fixes: #1053
OpenFilesScreen.c:229:65: error: format specifies type 'unsigned long long' but the argument has type '__off_t' (aka 'long') [-Werror,-Wformat]
xSnprintf(fileSizeBuf, sizeof(fileSizeBuf), "%"PRIu64, st.st_size); /* st.st_size is long long on macOS, long on linux */

If a fatal error occurs before CRT_init has been called, CRT_done
dereferences NULL in CRT_colors.
Simply check if CRT_crashSettings is not NULL, which is eventually
set when CRT_init has been called.
If it is not set, then do not try to disable ncurses.
Proof of Concept (on Linux):
$ ./configure --with-proc=/var/empty
$ make
$ ./htop
As the loop checks `tree_depth`, a tree build is needed to ensure
they're filled in correctly. Note that this breaks the display list sort
order in case it's non-tree-based (either startup in flat mode, or `*`
hotkey in flat mode), so the display list will need to be sorted again.
The PROCESS_MAX_UID_DIGITS=19 introduced in
696f79fe50 doesn't make sense.
The `uid_t` type does not require to be signed in POSIX. If we are to
support 64 bits as the maximum size of `uid_t`, then
PROCESS_MAX_UID_DIGITS should be 20. (= floor(log10(UINT64_MAX)) + 1).

* The size of titleBuffer should be 257 bytes, not 256.
* Remove redundant `static char titleBuffer[]` delarations within
`alignedProcessFieldTitle()` and let the subroutine use one shared
buffer for printing field title. This reduces code size.

Title width of "CPUD%" and "SWAPD%" is 5 and there value cannot go
beyond "100.0%", so increase their field width to 5.
"IOD%" is similar to "MEM%" column, title width is 4 and maximum value
cannot go beyond "100.0%". So in case of "IOD%" column, there is no need
to increase title width to "5". "Process_printPercentage()" function
will handle the maximum value case, it will display value beyond "99.9%"
as "100" instead of "100.0".
Since commit edf319e[1], we're dynamically adjusting column width of
"CPU%", showing single digit precision also for values greater than
"99.9%" makes "CPU%" column consistent with all other values.
[1]: edf319e53d
Change "Process_printPercentage()" function's logic to always display
value (i.e. "val") with single precision. Except when value is greater
than "99.9%" for columns like "MEM%", whose width is fixed to "4" and
value cannot go beyond "100%".
Credits: @Explorer09, thanks for the patch[2] to fix title alignment
issue.
