Explorer09 3512971084 Fix configure 'major' workaround causing <sys/sysmacros.h> to miss.
A logic mistake in pull request #746 causes <sys/sysmacro.h> to be
*not* included when AC_HEADER_MAJOR (before autoconf-2.70) finds
'major' in <sys/types.h>. Though this would still build htop, it would
still bring deprecation warning in systems using glibc 2.25-2.27. Fix
the logic and suppress the warning.

Also, include config.h in Process.c for the sake of strengthening the
code.

Wataru Ashihara 41754e5632
Remove unnecessary HAVE_SYS_SYSMACROS_H check
HAVE_SYS_SYSMACROS_H is always true if MAJOR_IN_SYSMACROS.

This way of checking is recommended in autoconf 2.70 documentation:
https://git.savannah.gnu.org/gitweb/?p=autoconf.git;a=blobdiff;f=doc/autoconf.texi;h=4f041bd4e;hp=9ad7dc1c5f02c8ba25b2fe1218bf931c7113a5d5;hb=e17a30e987d7ee695fb4294a82d987ec3dc9b974;hpb=565a6dc50cfa01cec2fb4db894026689cdf4970c

NOTE: currently
      https://www.gnu.org/software/autoconf/manual/autoconf.html is the
      doc for autoconf 2.69.

Kang-Che Sung (宋岡哲) c01f40eb3e Fix build failure ('major' undefined) in glibc 2.28. (#746)
glibc 2.28 no longer defines 'major' and 'minor' in <sys/types.h> and
requires us to include <sys/sysmacros.h>. (glibc 2.25 starts
deprecating the macros in <sys/types.h>.) Now do include the latter if
found on the system.

At the moment, let's also utilize AC_HEADER_MAJOR in configure script.
However as Autoconf 2.69 has not yet updated the AC_HEADER_MAJOR macro
to reflect the glibc change [1], so add a workaround code.

Fixes #663. Supersedes pull request #729.

I was occasionally passing negative values to size_t.
Plus, this better reflects the intent of the variant argument.

Vladimir Panteleev 87be623eac 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.

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.

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.

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.
