integration tests detect segmentation fault

Implement detection of segmentation fault in integration tests.

Nechytas tam nekde segfault a nevracis 1? Kazdy segfault mi skonci s retcode 1

Hm, SigHandler::handler má exit(1) a chytá sigsegv :-)

Mrkni sem - https://www.tldp.org/LDP/abs/html/exitcodes.html

V unixu jsou specialni retcodes. Pokud zabijes program signalem X, pak se vraci 128+x. V nasem pripade, SIGSEGV=11, tedy 139. Nejak to poupravim. (blbost, to je pro bash, nas se asi bude tykat sysexits.h)

Jeste pozorovani:

• kdyz zakazu signal(sigsegv), waitpid to pak odchyti jako nespravne ukonceny - signalem 11. Timeout je signal 15.
• kdyz ho necham povoleny, vrati se ta exit(1) z handler().
• V release mode se signal nechyta.

Jinak je to na to pripravene, je tedy jen potreba dovymyslet co s tim sighandlerem.
