This patch series adds sampling event overflow detection capability
to libperf.

First patch fixes a typo in the error message that I noticed.

Second patch  adds a interface to set PERF_FLAG_FD_CLOEXEC

Third patch adds a interface to perform IOC_REFRESH and IOC_PERIOD.

Fourth patch adds a interface to set the signal handler.

Fifth patch adds a interface to detect overflowed events.

Sixth and seventh patch adds tests.
