perf tools: Add strfilter for general purpose string filter
Add strfilter for general purpose string filter.
Every filter rules are descrived by glob matching pattern and '!' prefix
which means Logical NOT.
A strfilter consists of those filter rules connected with '&' and '|'.
A set of rules can be folded by using '(' and ')'.
It also accepts spaces around rules and those operators.
Format:
<rule> ::= <glob-exp> | "!" <rule> | <rule> <op> <rule> | "(" <rule> ")"
<op> ::= "&" | "|"
e.g.:
"(add* | del*) & *timer" filter rules pass strings which start with add
or del and end with timer.
This will be used by perf probe --filter.
Changes in V2:
- Fix to check result of strdup() and strfilter__alloc().
- Encapsulate and simplify interfaces as like regex(3).
