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.
