Calls marked with xSnprintf shouldn't fail.
Abort program cleanly if any of them does.

The (this_) token was not expanded properly, but the bug was not caught
because all uses of this macro specifies (this_)=this .

Also parenthesize macro tokens to prevent further problems.

* size_t nmemb (number of elements) first, then size_t size
* do not assume char is size 1 but use sizeof()
* allocate for char, not pointer to char (found by Michael McConville,
  fixes #261)

Fixes building on case-insensitive filesystems where String.h gets confused with <string.h>.

Subject: [PATCH 1/8] Rename String to StringUtils

Kinda runs, but functionality from the original main loop
is still missing. Patience.

This is a work-in-progress, code is currently broken.
(Some actions, and notably, the header, are missing.)

Set up environment to move other meters.

(Yes, that's dynamic typing!)

(Patch by Dawid Gajownik)

Changes in object model: separate class objects to store vtable. Also, nicer UTF-8 display of big numbers.

* Performance improvements
* Support for splitting CPU meters into two or four columns
  (thanks to Wim Heirman)
* Switch from PLPA, which is now deprecated, to HWLOC.
* Bring back support for native Linux sched_setaffinity,
  so we don't have to use HWLOC where we don't need to.
* Support for typing in user names and column fields in selection panels.

  (thanks to Sean Noonan)
* Meters update in every screen (no longer halting while on Setup, etc.)

disable useless code in release builds such as runtime type-checking on
dynamic data structures and process fields that are not being computed,
faster(?) method for verifying the process owner (still need to ensure
correctness), don't destroy and create process objects for hidden kernel
threads over and over. Phew. I shouldn't be doing all this today, but I
could not resist.

- add AllCPUsMeter;
- because of that, the new .htoprc is incompatible with previous released versions.
