Hisham Muhammad 543d65c6ab Security review: make privilege dropping-restoring optional.
This is/was necessary only on macOS, because you needed root in order
to read the process list. This was never necessary on Linux, and
it also raises security concerns, so now it needs to be enabled
explicitly at build time.

Hisham Muhammad e940aecfb9 Add "no perm" status when other fields fail due to lack of permission.
Thanks @Sworddragon for the heads up.
See #88.

Tomasz Kramkowski 2b5c1b4b13 Replace all uses of sprintf with snprintf
In all the cases where sprintf was being used within htop, snprintf
could have been used. This patch replaces all uses of sprintf with
snprintf which makes sure that if a buffer is too small to hold the
resulting string, the string is simply cut short instead of causing
a buffer overflow which leads to undefined behaviour.

`sizeof(variable)` was used in these cases, as opposed to `sizeof
variable` which is my personal preference because `sizeof(variable)`
was already used in one way or another in other parts of the code.

Ivan Kozik 07086fcf77 Fix column misalignment for priority -101 threads
BFS-patched kernels can have kernel threads with priority -101.
This change makes priority -101 display as "RT", just like priority -100.

Tobias Geerinckx-Rice 293eec4265 New setting: "Show program path"
Add a setting to hide all but the last component from the programme
path, leaving only the "basename". Makes htop more usable on smaller
screens, or systems with longer than average paths. Off by default.

"Highlight program basename" will still be respected, to further
visually separate process names from their arguments.
