Because OpenSSL's version numbers are not compatible with the CocoaPods version numbering, we will agree on the following.
OpenSSL version: A.B.CD will become A.B.C*100 + place of D in the alphabet (indexed by 1).
Example: OpenSSL 1.0.1h => OpenSSL 1.0.108
Update the podspec to reference the latest 1.0.* tarball and sha256 checksum from https://www.openssl.org/source/
note the 1.1.* series has some changes that aren't compatible with our existing build script.
note Most cocoapods podspecs reside within the same repository as
the source that they build. The source option in your podspec
references an external source location; However, using source doesn't
play nicely with development pods or referencing a pod via git URL.
