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.

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.

efaaf6eb77 Extending the cpu number from 32 to 1024 (bgo #323354, bgo #681632) 
From: Jason Xing <xinggang861@gmail.com>

In 'Bug 323354 - Support a dynamic number of CPUs', there will be a
solution which can dynamically allocate memory for large number of
CPUs. As libgtop supports multiple operating systems, this work
may take some time.

This patch is a temporary patch, which worked before the whole
solution comes out. It only supports linux platform with CPU number
up to 1024.

There are two Macroes which limit the statistics of CPU. One is
GLIBTOP_NCPU. The other is a buffer size. This buffer used to read
/proc/stat contents into.

47bcd423b5 Linux cpuinfo count fixed for SMP PPC processors (bgo #621831) 
libgtop processor count has been simply determined by the number
of sections in /proc/cpuinfo split by \n\n. On PPC processors
supporting SMP after the per-cpu description for each core a
new section is listed (after \n\n) with the common attributes
of the cores [1]. Work around this by only counting a section
as describing a CPU if it contains "processor" to fix bug #621831 [0]

37774dc02d fsusage: Fix fetching rootfs stats on Fedora 17 
When fsusage scans mtab, it matches on the first entry, but since 'rootfs'
isn't of the expected format '/dev/<blah>' it bails out.

Match early on any rootfs entries and skip them.
