Peter Zhu 2350c79462 Use xfree for IO::Buffer
Since IO::Buffer is allocated using TypedData_Make_Struct, it must use
xfree to free the buffer otherwise it will cause more major GC to run.

Example:

```
10.times do
  1_000_000.times { IO::Buffer.new(0) }

  puts "oldmalloc_increase_bytes: #{GC.stat(:oldmalloc_increase_bytes)}, major_gc_count: #{GC.stat(:major_gc_count)}"
end
```

Before:

```
oldmalloc_increase_bytes: 14904176, major_gc_count: 3
oldmalloc_increase_bytes: 2399424, major_gc_count: 5
oldmalloc_increase_bytes: 5204640, major_gc_count: 6
oldmalloc_increase_bytes: 2199936, major_gc_count: 7
oldmalloc_increase_bytes: 34199936, major_gc_count: 7
oldmalloc_increase_bytes: 24223360, major_gc_count: 8
oldmalloc_increase_bytes: 5967616, major_gc_count: 9
oldmalloc_increase_bytes: 37967616, major_gc_count: 9
oldmalloc_increase_bytes: 9689792, major_gc_count: 10
oldmalloc_increase_bytes: 41689792, major_gc_count: 10
```

After:

```
oldmalloc_increase_bytes: 117392, major_gc_count: 2
oldmalloc_increase_bytes: 26128, major_gc_count: 2
oldmalloc_increase_bytes: 71600, major_gc_count: 2
oldmalloc_increase_bytes: 117072, major_gc_count: 2
oldmalloc_increase_bytes: 17296, major_gc_count: 2
oldmalloc_increase_bytes: 62768, major_gc_count: 2
oldmalloc_increase_bytes: 108240, major_gc_count: 2
oldmalloc_increase_bytes: 153712, major_gc_count: 2
oldmalloc_increase_bytes: 53936, major_gc_count: 2
oldmalloc_increase_bytes: 99408, major_gc_count: 2
```

Don't warn generally for `IO::Buffer`, only on specific code paths e.g. `map`. (#9131) 2023-12-06 13:42:45 +13:00

Fix `io_buffer_get_string` default length computation. (#8427)
* Fix `io_buffer_get_string` default length computation.

When an offset bigger than the size is given, the resulting length will be
computed incorrectly. Raise an argument error in this case.

* Validate all arguments.

IO::Buffer#resize: Free internal buffer if new size is zero (#7569)
`#resize(0)` on an IO::Buffer with internal buffer allocated will
result in calling `realloc(data->base, 0)`. The behavior of `realloc`
with size = 0 is implementation-defined (glibc frees the object
and returns NULL, while BSDs return an inaccessible object). And
thus such usage is deprecated in standard C (upcoming C23 will make it
UB).

To avoid this problem, just `free`s the memory when the new size is zero.
