Harden the extraction of boot time for the Linux platform
...
There is a possible path - albeit theoretical really - through
the btime initialization code in Linux ProcessList_new(), when
String_startsWith() is always false, which can result in btime
not being initialized.
This commit refactors the code to remove that possibility.

Cleanup initialization of jiffies on the Linux platform

Small cleanups - add error handling, remove a local static

it, as its in LinuxProcessList.c not LinuxProcess.c) - and
while there, move the related 'btime' global variable into
LinuxProcessList.c so it can be made static.

Cull the definitions of pageSize and pageSizeKB from CRT.c
...
By storing the per-process m_resident and m_virt values in the form
htop wants to display them in (KB, not pages), we no longer need to
have definitions of pageSize and pageSizeKB in the common CRT code.
These variables were never really CRT (i.e. display) related in the
first place. It turns out the darwin platform code doesn't need to
use these at all (the process values are extracted from the kernel
in bytes not pages) and the other platforms can each use their own
local pagesize variables, in more appropriate locations.
Some platforms were actually already doing this, so this change is
removing duplication of logic and variables there.

its not been anything other than zero in Linux /proc/meminfo

usedMem calculation, so it can reside on the stack like some
other memory variables used within-calculations-only and not
exposed to the user via a Meter.

Axe automated header generation.
...
Reasoning:
- implementation was unsound -- broke down when I added a fairly
basic macro definition expanding to a struct initializer in a *.c
file.
- made it way too easy (e.g. via otherwise totally innocuous git
commands) to end up with timestamps such that it always ran
MakeHeader.py but never used its output, leading to overbuild noise
when running what should be a null 'make'.
- but mostly: it's just an awkward way of dealing with C code.

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.
