f99bb61446 procstate: Fill in last_processor member on linux 
The field was added almost 20 years ago, but has only been set on
Solaris so far. It turns out we have a use for it now in the new
"Usage" application, so also fill it in on Linux.

59d9780eae freebsd: Support GLIBTOP_IF_FLAGS_WIRELESS in netload 
The ioctl call used in this patch doesn't seems to be documented. It is
what ifconfig(8) command uses to display the media type, and its usage
can be learned by reading the source code of ifconfig(8).

305701c637 freebsd: Rewrite netload implementation with getifaddrs and ioctl 
Instead of using a documented and official API to get information related
to a network interface, the old implementation uses kvm library to access
kernel memory directly, which is not easy to understand and can be easily
broken by changing kernel symbols or structs. Besides, FreeBSD 11 hides
severai required kernel struct definitions from userspace programs, which
causes compilation error because the definition of 'struct ifaddr' is not
available unless _KERNEL is defined.

This patch is primarily authored by Gleb Smirnoff <glebius@FreeBSD.org>,
with other simple modification made by Antoine Brodin <antoine@FreeBSD.org>,
Koop Mast <kwm@FreeBSD.org> and Ting-Wei Lan <lantw@src.gnome.org> applied.
It was first submitted to FreeBSD ports and has been used by FreeBSD users
for more than 18 months on all supported versions of FreeBSD.

94968b4406 Fix building on musl-libc 
libgtop fails to build on musl libc, due to the header
resulting in the headers that would be loaded for libc 5 being
loaded on musl libc.
musl defines headers which are also defined in linux-headers'
in.h, causing redefinition errors.

887092a05d Define glibtop_debug(_r) as macros, eventually calling real C function. 
Keep these as macros so that if debug is not enable, although the
debug message is parsed, it's not run.
It's better this way because the debug message is always parsed and
checked instead of being deleted by the preprocessor.

0580b2fb2c Linux >= 3.14 provides a "MemAvailable" field in /proc/meminfo which gives the 
estimated amount of memory available for applications.
Use this to compute glibtop_mem::user.

a206cfc728 freebsd: rework system memory usage 
Change the value of memory usage from:

  Used   = Wired
  Free   = Total - Wired
  Shared = 0
  Buffer = 0
  Cached = Cache
  User   = Wired - Cache
  Locked = Not Supported

To:

  Used   = Total - Free
  Free   = Free
  Shared = 0
  Buffer = Buf
  Cached = Cache
  User   = Active + Wired
  Locked = Not Supported

The left-hand side means fields in the glibtop_mem struct and the right-hand
side means the value showed by `top' command. This change should make the value
showed by gnome-system-monitor, which uses `User' field, become closer to
the real memory usage.

All sysctlbyname code in sysdeps/freebsd/mem.c has been moved to separate
functions to make the code cleaner.
