string.c: fix false coderange
* string.c (rb_enc_str_scrub): enc can differ from the actual
encoding of the string, the cached coderange is useless then.

Introduce rb_str_tmp_frozen_acquire and rb_str_tmp_frozen_release
to manage a hidden, frozen string. Reuse one bit of the embed
length for shared strings as STR_IS_SHARED_M to indicate a string
has been shared multiple times. In the common case, the string
is only shared once so the object slot can be reclaimed immediately.

GCC 6 and Clang 3.8 prefers int over void to correctly detect
necessary attributes under this setup. Maybe subject to change
in future.

The behavior on signed integer overflow is undefined. On platform with
sizeof(long)==4, it's fairly easy that 'len + termlen' overflows, where
len is the string length and termlen is the terminator length.
So, prevent the integer overflow by avoiding adding to a string length,
or casting to size_t before adding where the total size is passed to
{RE,}ALLOC*().
* string.c (STR_HEAP_SIZE, RESIZE_CAPA_TERM, str_new0, rb_str_buf_new,
str_shared_replace, rb_str_init, str_make_independent_expand,
rb_str_resize): Avoid overflow by casting the length to size_t. size_t
should be able to represent LONG_MAX+termlen.
* string.c (rb_str_modify_expand): Check that the new length is in the
range of long before resizing. Also refactor to use RESIZE_CAPA_TERM
macro.
* string.c (str_buf_cat): Fix so that it does not create a negative
length String. Also fix the condition for 'string sizes too big', the
total length can be up to LONG_MAX.
* string.c (rb_str_plus): Check the resulting String length does not
exceed LONG_MAX.
* string.c (rb_str_dump): Fix integer overflow. The dump result will be
longer then the original String.

* string.c (STR_BUF_MIN_SIZE): reduce from 128 to 127
[ruby-core:76371] [Feature #12025]
* string.c (rb_str_buf_new): adjust for above reduction
From Jeremy Evans <code@jeremyevans.net>:
This changes the minimum buffer size for string buffers from 128 to
127. The underlying C buffer is always 1 more than the ruby buffer,
so this changes the actual amount of memory used for the minimum
string buffer from 129 to 128. This makes it much easier on the
malloc implementation, as evidenced by the following code (note that
time -l is used here, but Linux systems may need time -v).
$ cat bench_mem.rb
i = ARGV.first.to_i
Array.new(1000000){" " * i}
$ /usr/bin/time -l ruby bench_mem.rb 128
3.10 real 2.19 user 0.46 sys
289080 maximum resident set size
72673 minor page faults
13 block output operations
29 voluntary context switches
$ /usr/bin/time -l ruby bench_mem.rb 127
2.64 real 2.09 user 0.27 sys
162720 maximum resident set size
40966 minor page faults
2 block output operations
4 voluntary context switches
To try to ensure a power-of-2 growth, when a ruby string capacity
needs to be increased, after doubling the capacity, add one. This
ensures the ruby capacity will be odd, which means actual amount
of memory used will be even, which is probably better than the
current case of the ruby capacity being even and the actual amount
of memory used being odd.
A very similar patch was proposed 4 years ago in feature #5875. It
ended up being rejected, because no performance increase was shown.
One reason for that is that ruby does not use STR_BUF_MIN_SIZE
unless rb_str_buf_new is called, and that previously did not have
a ruby API, only a C API, so unless you were using a C extension
that called it, there would be no performance increase.
With the recently proposed feature #12024, String.buffer is added,
which is a ruby API for creating string buffers. Using
String.buffer(100) wastes much less memory with this patch, as the
malloc implementation can more easily deal with the power-of-2
sized memory usage. As measured above, memory usage is 44% less,
and performance is 17% better.
