Bug #408803: innodbbackupex reaches Servers wait_timeout

The problem was the flawed keep-alive logic in innobackupex: keep-alive
queries were only sent to server when mysql_keep_alive() or
mysql_check() were explicitly called. Which led to connection timeouts
when some activity between those calls (e.g. copying a large non-InnoDB
file) took longer than server's wait_timeout.

Fixed innobackupex so that keep-alive queries are now sent automatically
using alarms. The time interval was also reduced from 1800 to 5 seconds
to accommodate low wait_timeout values. Since there is no need for
explicit calls to mysql_check() and mysql_keep_alive(), those functions
were removed.

There is no test case, because time sensitive tests for innobackupex are
basically impossible.

Bug #884737: xtrabackup's --parallel option asserts / crashes with a
             value of -1

The problem was that my_getopt was implicitly converting negative
values to large positive ones, so xtrabackup would fail with an
asserts / crashes due to resource shortage.

Fixed by changing 'parallel' to a signed option so negative values are
detected and adjusted to the default value of 1 by my_getopt.
