The variables "[fReopenDebugLog](https://github.com/bitcoin/bitcoin/blob/fa24439ff3d8ab5b9efaf66ef4dae6713b88cb35/src/util.h#L53)" and "[fRequestShutdown](https://github.com/bitcoin/bitcoin/blob/fae78fa81802b5387054715c339f286ef436408e/src/init.cpp#L128)" should [use the data type "sig_atomic_t"](https://www.securecoding.cert.org/confluence/display/c/SIG31-C.+Do+not+access+shared+objects+in+signal+handlers) (instead of "bool").

I reported this issue for [another evolving software](https://github.com/Electric-Coin-Company/zcash/issues/678) before.
