* string.c: Specify termlen as far as possible.
Additional fix for [Bug #12536] [ruby-dev:49699].
* string.c (rb_usascii_str_new, rb_utf8_str_new): Specify termlen
which is apparently 1 for the encodings.
* string.c (str_new0_cstr): New static function to create a String
object from a C string with specifying termlen.
* string.c (rb_usascii_str_new_cstr, rb_utf8_str_new_cstr): Specify
termlen by using new str_new0_cstr().
* string.c (str_new_static): Specify termlen from the given encoding
when creating a new String object is needed.
* string.c (rb_tainted_str_new_with_enc): New function to create a
tainted String object with the given encoding. This means that
the termlen is correctly specified. Curretly static function.
The function name might be renamed to rb_tainted_enc_str_new
or rb_enc_tainted_str_new.
* string.c (rb_external_str_new_with_enc): Use encoding by using the
above rb_tainted_str_new_with_enc().
