[ruby/zlib] Don't call `rb_str_set_len` while released the GVL.
(https://github.com/ruby/zlib/pull/88)
* Only release the GVL where necessary.
- Several string manipulation methods were invoked while the GVL was
released. This is unsafe.
- The mutex protecting multi-threaded access was not covering buffer state
manipulation, leading to data corruption and out-of-bounds writes.
- Using `rb_str_locktmp` prevents changes to buffer while it's in use.
[Bug #20863]
