ae02a6cbb8 Implement inject and fault actions
* basic_actions.c (not_injected, apply_inject, parse_inject_common,
parse_inject, apply_fault, parse_fault): New functions.
* defs.h (struct inject_opts): Add init flag.
(qual_flags): Remove declaration.
* filter_action.c (action_types): Add inject and fault action types.
(set_filter_action_priv_data): New function.
* filter_qualify.c (inject_set): Remove variable.
(parse_inject_expression): Remove function.
(parse_inject_common_args): Add function for inject/fault arguments parsing.
(qualify_inject_common): Use parse_inject_common_args instead of
parse_inject_expression, use new filtering API.
(qualify_fault, qualify_inject): Remove "argument" from description
argument of qualify_inject_common.
(qual_flags): Remove function.

set_filter_action_priv_data): New declarations.
(DECL_FILTER_ACTION): Declare inject and fault actions.
(DECL_FILTER_ACTION_PARSER): Declare inject and fault action parsers.
* strace.c (trace_syscall): Call filter_syscall only when tcp->qual_flg
is empty.

4c2d68c14b Introduce new filtering architecture
This change introduces new filtering architecture primitives: filter,
filter_action and bool_expression. Filtering is now done after decoding of
syscall and tcp->qual_flg stores filtering results.

* basic_actions.c: New file.
* filter_action.c: Likewise.
* filter_expression.c: Likewise.
* filter.c: Likewise.
* basic_filters.c (parse_syscall_filter, run_syscall_filter,
free_syscall_filter): New functions.
* defs.h (filter_syscall, filtering_parsing_finish): Add new declarations.
* filter.h: Add new declarations.
* filter_qualify.c (abbrev_set, raw_set, trace_set, verbose_set):
Remove set variables.
(qualify_trace, qualify_abbrev, qualify_verbose, qualify_raw):
Use new filtering API.
(qual_flags): Remove QUAL_* flags for trace, abbrev, verbose, raw.
* strace.c (init): Call filtering_parse_finish after command line parsing.
(trace_syscall): Add filtering after syscall decoding.
* Makefile.am (strace_SOURCES): Add new files.
