Description:
------------
mb_detect_encoding() produces wrong results from incomplete multibyte sequences when strict_mode is turned on. (originally reported by komura.db2r1e|at|gmail|dot|com)

Reproduce code:
---------------
// non-strict mode
var_dump(mb_detect_encoding("A\x81", "SJIS", false));
// strict mode
var_dump(mb_detect_encoding("A\x81", "SJIS", true));
// non-strict mode
var_dump(mb_detect_encoding("\xc0\x00", "UTF-8", false));
// strict mode
var_dump(mb_detect_encoding("\xc0\x00", "UTF-8", true));

Expected result:
----------------
string(4) "SJIS"
bool(false)
string(5) "UTF-8"
bool(false)


Actual result:
--------------
string(4) "SJIS"
string(4) "SJIS"
string(5) "UTF-8"
string(5) "UTF-8"
