Rin Cat (鈴猫) 07496eafb0 Linux: use proper way to detect kernel threads
Use PF_KTHREAD flag in /proc/[pid]/stat to detect kernel threads.
This fixed an issue when a process's cmdline is empty, htop think
it is a kernel thread.

Benny Baumann 2977414d54 Discard stale information from DiskIO and NetworkIO meters
This ensures the initial read of the data is not misinterpreted as arbitrarily large values.
Also this forces the maximum update interval between two subsequent reads to within 30s.

Fixes #860

Silke Hofstra 696f79fe50 Dynamically scale the ST_UID size to support 32-bit UIDs
While most Unix-like systems use 16-bit user IDs,
Linux supports 32-bit UIDs since version 2.6.
UIDs above 65535 are used for UID namespacing of containers,
where a container has its own set of 16-bit user IDs.
Processes in such containers will have (much) larger UIDs than 65535.

Because the current format strings for `ST_UID` and `USER`
are `%5d` and `%9d` respectively, processes with such UIDs
lead to misaligned columns.

Dynamically scale the `ST_UID` column and increase the size of `USER`
to 10 characters (length of UINT32_MAX) to ensure that the user ID always fits.

Additionally: clean up how the titlebuffer size calculation and ensure
the PID column has a minimum size of 5.

Lucas Werkmeister 731b4003a2 Fix Security Attributes column header width
Limit the maximum width (instead of only the minimum width), pad the
header width accordingly, and also remove extra stray spaces from the
format string (the main spacing should just come from the alignment of
the value).

Fixes #850.

- devstat_getdevs()
- devstat_selectdevs()
- devstat_buildmatch()
- get_devstat_kvm()

Nathan Scott 8ac8542b6e Handle interrupted sampling from within libpcp PDU transfers
This situation can arise if pcp-htop screen is resized right
at the same time sampling from pmcd(1) is happening.  Have a
couple more goes at it before giving up entirely; once there
is no data available though we cannot proceed into accessing
the sample result data structure (segv will result) so a new
short-circuit guard is added there also.

Ximalas 9eb52d5932 Release memory for cmdline when Process_updateCmdline() returns.
This closes a nasty memory leak. There is at least another leak looming somewhere when Disk I/O is shown in the header area. That could very well be an issue within libdevstat native to FreeBSD.

Christian Göttsche 970885edc3 Linux: improve tryRead macro safety
Add an explicit else clause so a following else branch for a prior if
condition does not get mixed up.

Also force a trailing semicolon and thereby silence current
-Wextra-semi-stmt warnings.

Improve readability of the hwloc_bitmap_foreach_begin loop macro.

Sohaib Mohamed 8932efece9 astyle: Add `--pad-header` option
Insert space padding between a header (e.g. 'if', 'for', 'while'...) and the
following paren. ex:

if(isFoo((a+2), b))
    bar(a, b);

becomes:

if (isFoo((a+2), b))
    bar(a, b);
