Christian Göttsche 1275139795 Settings_write: fix return value on error 
Return a negative errno on fprintf() or flcose() failure, not a return
value of ferror() or flcose().

Christian Göttsche 0cfc9b0980 LinuxProcessList: refactor /proc/stat parsing 
Combine reading CPU count and CPU usage, only open the file once.
Do not separately initialize totalPeriod and totalTime, cause the value
0 is handled in Platform_setCPUValues().

Take the number of currently running process from the entry
procs_running in /proc/stat instead of counting all scanned process
with state 'R', to include hidden tasks, e.g. threads.

Christian Göttsche 521f1343e3 Settings: check if writing configuration file was successful 
Writing to the file stream might fail due to a immutable file or a
filesystem error.
Check the error indicator for the stream and for fclose() failures.

Christian Göttsche bea7f8e7af Process_compare: reorder checks 
Check for result being 0 first, before checking if the result might be
negated, so we do not need to negate 0.

Christian Göttsche 8ba4ef327e configure: use portable AND 
man:test(1)
    NOTE: Binary -a and -o are inherently ambiguous.  Use 'test EXPR1 &&
    test EXPR2' or 'test EXPR1 || test EXPR2' instead.

Also fix indent

Nathan Scott 61ef1134d9 Move generic (shared) code into its own sub-directory 
Code that is shared across some (but not all) platforms
is moved into a 'generic' home. Makefile.am cleanups to
match plus some minor alphabetic reordering/formatting.

Nathan Scott 5b50ae3aa3 Separate display from sampling in SysArch and Hostname Meters 
Several of our newer meters have merged coding concerns in terms
of extracting values and displaying those values.  This commit
rectifies that for the SysArch and Hostname meters, allowing use
of this code with alternative front/back ends.  The SysArch code
is also refined to detect whether the platform has an os-release
file at all and/or the sys/utsname.h header via configure.ac.

Nathan Scott 00339087b0 Fix integer sizing issues in the DiskIO Meter 
On Linux kernels the size of the values exported for block
device bytes has used a 64 bit integer for quite some time
(2.6+ IIRC).  Make the procfs value extraction use correct
types and change internal types used to rate convert these
counters (within the DiskIO Meter) 64 bit integers, where
appropriate.

feature in their packages by default.
