Move sysfs-reading code to LinuxProcessList.c and add average frequency.
...
This way the frequency is read from sysfs only once per update cycle
instead of every time the UI is redrawn.
This also changes the code to read from /proc/cpuinfo instead. This is because
reading from scaling_cur_freq stalls for 10ms if the previous read for the file
was more than one second ago. [1] Since htop's update cycle is
longer than that, it would cause the read of each CPU's scaling_cur_freq file
to block the UI for 20ms. This easily led to a noticeable half-second lag on
a 20+ CPU machine.
/proc/cpuinfo also has a 10ms delay, but this applies for the whole file
so the delay does not scale with the number of CPUs. [2]

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 .

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.

Introduce CLAMP macro. Unify all MIN(MAX(a,b),c) uses.
...
With the CLAMP macro replacing the combination of MIN and MAX, we will
have at least two advantages:
1. It's more obvious semantically.
2. There are no more mixes of confusing uses like MIN(MAX(a,b),c) and
MAX(MIN(a,b),c) and MIN(a,MAX(b,c)) appearing everywhere. We unify
the 'clamping' with a single macro.
Note that the behavior of this CLAMP macro is different from
the combination `MAX(low,MIN(x,high))`.
* This CLAMP macro expands to two comparisons instead of three from
MAX and MIN combination. In theory, this makes the code slightly
smaller, in case that (low) or (high) or both are computed at
runtime, so that compilers cannot optimize them. (The third
comparison will matter if (low)>(high); see below.)
* CLAMP has a side effect, that if (low)>(high) it will produce weird
results. Unlike MIN & MAX which will force either (low) or (high) to
win. No assertion of ((low)<=(high)) is done in this macro, for now.
This CLAMP macro is implemented like described in glib
<http://developer.gnome.org/glib/stable/glib-Standard-Macros.html >
and does not handle weird uses like CLAMP(a++, low++, high--) .
