These structures allow for blobs of data (e.g. certificates) to be

Instead, each module defines a static CRYPTO_EX_DATA_CLASS to hold the values.
This makes CRYPTO_cleanup_all_ex_data a no-op as spreading the
CRYPTO_EX_DATA_CLASSes across modules (and across crypto and ssl) makes cleanup
slightly trickier. We can make it do something if needbe, but it's probably not
worth the trouble.

Also, Clang doesn't like static asserts with the same message and
ERR_free_strings should still free the error queues, although it's badly
misnamed now.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.

This doesn't work on Windows.

This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
