[openssl-dev] Doubt about memory realloc logic in BUF_MEM_grow_clean and BUF_MEM_grow

[Raja ashok]

Hi Salz,

I raised a PR for this change. Already got some comments from Kurt. Requesting you also to check and provide your suggestions on it.
https://github.com/openssl/openssl/pull/3255

Currently raised PR on only 1.0.2. Once its reviewed, I can raise on other branches (1.1.0 and Master).

The intent is to blank out everything from what was currently written.  This "covers up" possible pointer over-runs.

We could do just from the old max.
