termlen and resize heap for the terminator. This is split from
rb_str_fill_terminator (str_fill_term) because filling terminator
and changing terminator length are different things. [Bug #12536]
* internal.h: declaration for rb_str_change_terminator_length.
* string.c (str_fill_term): Simplify only to zero-fill the terminator.
For non-shared strings, it assumes that (capa + termlen) bytes of
heap is allocated. This partially reverts r55557.
* encoding.c (rb_enc_associate_index): rb_str_change_terminator_length
is used, and it should be called whenever the termlen is changed.
* string.c (str_capacity): New static function to return capacity
of a string with the given termlen, because the termlen may
sometimes be different from TERM_LEN(str) especially during
changing termlen or filling terminator with specific termlen.
* string.c (rb_str_capacity): Use str_capacity.

In this fix, if possible, decrease capa instead of realloc.

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().

[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.
* string.c (rb_str_capacity, str_shared_replace, str_buf_cat): ditto.
* string.c (rb_str_drop_bytes, rb_str_setbyte, str_byte_substr): ditto.
