[PATCH v4 0/6] New filtering architecture

[Nikolay Marchuk]

These patches implement new filtering architecture. Currently supported actions:
trace, inject, fault, read, write, raw, abbrev, verbose. Currently supported
filters: syscall, fd, path. New option for new filters is -m "...".
Changes in filtering language:
* Delimiter of action arguments is now ';'.
* Supported logical operators: and, or, not. Also C-like forms of these 
  operators are supported: &&, ||, !.
* Syscall filter accepts syscalls' set, class or regex with old set description
  syntax.

Changes since v1:
* qualify.c is now splitted in separate commit.

Changes since v2:
* Fixed segmentation fault in inject/fault parsing.
* basic_filters.c (run_fd_filter): Changed returns to true/false.

Changes since v3:
* Fixed invalid accounting of syscalls for inject/fault actions.
* Fixed order of filter actions with same priority.
* Refactored inject arguments parsing.
* Refactored fd filtering.
* Refactored tests for syscall set syntax.
* Improved diagnostics of filtering errors.
* Rewritten algorithms of parsing for new filtering language.

Nikolay Marchuk (6):
  Split qualify.c into basic_filters.c and filter_qualify.c
  Introduce new filtering architecture
  Improve fd filtering
  Optimize default filtering
  Implement new filtering language parsing
