Comment (by Ry):

 Please check the below branch for a partial implementation. Currently
 treating it like '--versions' and will exit after printing. Also updated
 the versions string after regular startup to include runtime zlib version
 (was already printing openssl and libevent).

 Haven't implemented hex-encoded versions yet, just need to clarify that
 we're just wanting the hexprint of the integer version number and not a
 hash of the actual lib or something? Is this also required for compile and
 runtime?

 Are we supporting zlib <= 1.1 as I think the ZLIB_VERNUM is only usable
 after that, but we can just parse the ZLIB_VERSION to get a similar output
 if necessary. Do you have any additional requirements for the hex-encoded
 versions?

 Thanks
