uuidd: remove timeout from systemd service file

It seems that SAP does not like the timeout, for performance is
better to keep the daemon permanently running. This is no problem
because uuidd is used only on systems with very unusual requirements
to UUID.

column: inform user when multibyte conversion occurs

The column(1) read input until conversion error, and used incomplete
input when outputing, that made at least me to wonder where the rest
disappeared without explanation.  IMHO it is better to fail immediately
rather than do only half of the task.

cytune: rename threshold and timeout variables

Especially the treshold was difficult to read, as the variable name had
no reference what it was setting.  Effect of the variables
s/get/get_current/ and s/get_def/get_defaults/ seem to documented wrong
way, that became apparent after looking into this name space.

cytune: use single loop for setting and getting ioctl() calls

This commit also fixes functional bug.  Documentation gives an idea one
might set current, and default values in one go but as a matter of fact
that did not work earlier.

cytune: kernel still does not have send_count in cyclades_monitor structure

It is unlikely the information about sent data will ever appear to kernel
interface, so stop waiting it.

cytune: prefer sigaction(), and remove unnecessary abstractions

The signal(3) system call is not exactly deprecated, but it should not be
used in new code.  The gettimeofday() does not require timezone to be
real variable, so get rid of it.  The mvtime #define was in use only
which make literal expression more readable.

cytune: pull signal handling and statistic priting apart

Combination of these two functions made the code to rely to global
variables, and cmon_index was seemingly invalid if signal was sent at a
time when query_tty_stats() was half done with a statistics printout.

cytune: deprecate undescriptive options

The options with 'flush' in the name are not very good.  Use of 'timeout'
instead is much more appropriate.
