Introduce -e inject= as a general injection option, limit -e fault= option to syscall fault injection. Change default return code of syscall fault injection to ENOSYS. * qualify.c (parse_inject_token): Add fault_tokens_only argument, do not accept retval= and signal= tokens when fault_tokens_only is set to true. (parse_inject_expression): Add fault_tokens_only argument, forward it to parse_inject_token. (qualify_inject_common): New function. (qualify_fault): Use it. (qualify_inject): New function. (qual_options): New entry. * strace.1: Describe -e inject= option. * NEWS: Mention -e inject= option. * tests/qual_fault-syntax.test: Test that -e fault= option does not support retval=, signal=, and multiple error= tokens. * tests/qual_fault.c (DEFAULT_ERRNO): Set to ENOSYS unconditionally. * tests/qual_inject-retval.test: Replace -e fault= option with -e inject= option. * tests/qual_inject-syntax.test: New test. * tests/Makefile.am (MISC_TESTS): Add it.
