<ctype.h> is included first without _GNU_SOURCE, so it ends up
including <string.h> without declaring strndup(). And further
<string.h> declarations, even with _GNU_SOURCE defined, are
of course without effect.
Therefore:
util/strfilter.c: Dans la fonction «strfilter_node__new» :
util/strfilter.c:134: attention : déclaration implicite de la fonction « «strndup» »
util/strfilter.c:134: attention : incompatible implicit declaration of built-in function «strndup»
make: *** [util/strfilter.o] Erreur 1
Just don't include ctype.h as it doesn't appear to be necessary
anyway.

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).
