string.c: Fix memory corruptions when using UTF-16/32 strings.
[Bug #12536] [ruby-dev:49699]
string.c (TERM_LEN_MAX): Macro for the longest TERM_FILL length,
the same as largest value of rb_enc_mbminlen(enc) among encodings.
string.c (str_new, rb_str_buf_new, str_shared_replace): Allocate
+TERM_LEN_MAX bytes instead of +1. This change may increase memory
usage.
string.c (rb_str_new_with_class): Use TERM_LEN of the "obj".
string.c (rb_str_plus, rb_str_justify): Use str_new0 which is aware
of termlen.
string.c (str_shared_replace): Copy +termlen bytes instead of +1.
string.c (rb_str_times): termlen should not be included in capa.
string.c (RESIZE_CAPA_TERM): When using RSTRING_EMBED_LEN_MAX,
termlen should be counted with it because embedded strings are
also processed by TERM_FILL.
