Change the parser of fault expression to follow the POLA: -e fault=!SET means that all syscalls except those from SET are subject to fault injection; -e fault=!SET1:error=ERRNO1, -e fault=!SET2:error=ERRNO2 means that all syscalls except those from SET2 are subject to fault injection with error code ERRNO2, and all syscalls from SET2 that are not in SET1 are subject to fault injection with error code ERRNO1. * syscall.c (qualify_scno, qualify_syscall_class, qualify_syscall_name): Handle negated QUAL_FAULT case differently. * tests/fault_syntax.test: Add checks of negated sets.
