openzfs_sysctl_init() now returns void instead of int.
The ZfsArcStats->enabled flag is set inside the init function
now, instead of having to be set from its return value.
Preparation for more flag setting in Compressed ARC commit.
ZfsArcMeter_readStats() added and all Meter->values[] setting
moved to it, eliminating duplicated code in
{darwin,freebsd,linux,solaris}/Platform.c.
If no pools are imported (ARC size == 0) or the
ZFS module is not in the kernel (/proc/spl/kstat/zfs/arcstats
does not exist), then the Meter reports "Unavailable".
New meter displays same ARC stats as FreeBSD top(1).
Can be extended to other platforms that support ZFS.
Pulling kstat.zfs.misc.arcstats.c_max as the meter
total, so the meter has a meaningful value to work
up to.
The Text meter displays, first, the maximum
ARC size (Meter.total), then second, the total
ARC used, using the difference between Meter.maxItems
and Meter.curItems to "hide" the used value from the
Bar and Graph drawing functions by using an index
in Meter.values[] that is beyond curItems - 1, but
less than maxItems - 1.
this way a remount of /proc will not reset starttimes
and we can also see startup times for processes started before the mount
of /proc
also record btime (boot time in seconds since epoch) as Linux semi-global
This would prevent a careless future package maintainer from creating a
release tarball with a defective configure script. :)
Also, add a warning in the autogen.sh phase if pkg.m4 is unused.

With this commit:
* if pkgconfig is installed, it will expand the code inside the shell if, adding the pkgconfig-based tests for the dependencies of Linux delay accounting.
* if pkgconfig is not installed, it will add an error message inside the test of Linux delay accounting, telling the user to install pkgconfig and rebuild the configure script if they want to use Linux delay accounting.
The end result is:
* people running Linux
* will not need pkgconfig when not using delay accounting
* will need pkgconfig when using delay accounting
* if they don't have it
* they are told by configure they need to install it and re-run autogen.sh when running from Git
* they are told by configure they need to install it and re-run configure when running from the tarball
* people not running Linux
* will never need pkgconfig
...and in none of the above scenarios the generated configure script produces unexpanded macros for users checking out the sources from Git.
Header creation fails with non-utf8 locale and python3.
Simply set LC_ALL="C" and use python3 to reproduce the issue.
env LC_ALL="C" ./scripts/MakeHeader.py MetersPanel.c

cStringIO.StringIO module is removed because it is not able to accept unicode strings

Squashed the following commits:
* Solaris: Get LWP enumeration working
* Solaris: Make showing and hiding of kernel threads behave
* Solaris: remove usage of lwpstatus that is no longer needed
* Solaris: no discrete access to parent proc structure needed
* Solaris: Restore runtime MaxPid detection after LWP changes
* Solaris: Workaround virtual PID signal issue by shadowing kill() with a macro
* Solaris: Fix unintention double-shifting of virtual PID for LWP enumeration
* Solaris: Add LWPID to default display since LWP enumeration is also default
* Solaris: use PAGE_SIZE_KB from Process.h instead of custom definition
* Solaris: stop LWP enumeration at 1023 LWPs per proc since that is all we can handle in the virtual PID
