I do not completely understand what is going on there, but I am pretty
sure dir_entry <= offset_base if not a normal situation, so we better not
to rely on such dir_entry.
`zend_string_tolower()` returns a copy (not a duplicate) of the given
string, if it is already in lower case. In this case we must not not
`zend_string_free()` both strings. The cleanest solution is to call
` zend_string_release()` on both strings, which properly handles the
refcount.
Optimizing compilers have an annoying tendency to throw out
memsets over data that they think aren't used anymore. Apply secure
zero-out in cases where this has potential to happen.
Oniguruma does not consistently perform this validation itself (at least
on older versions), so make sure we check pattern encoding validity on the
PHP side.
A behavior change in revealed by some openssl_decrypt() based test,
where an encrypt API is used with a decrypt context. The EVP_Cipher*
functions will automatically choose the right operation depending on the
context passed.

In order to rename safer, we do the following:
- set umask to 077 (unfortunately, not TS, so excluding ZTS)
- chown() first, to set proper group before allowing group access
- chmod() after, even if chown() fails

At least some of the image reading functions may return images which
use color indexes greater than or equal to im->colorsTotal. We cater
to this by always using a buffer size which is sufficient for
`gdMaxColors` in `gdImageColorMatch()`.
