This reverts commit d78ac04ee6.
The benefits of `ignore=all` are that submodules are omitted from
`git status` and `git citool`. The drawbacks are - submodules
are not omitted from `git commit -a` *and* they are omitted
from `git diff` and `git show` output.
As a result one can unintentionally commit changes to submodules and not
see it in the history. Thus drawbacks outweigh benefits here.
- Add new submodule for WolfSSL
- Build and use wolfssl and wolfcrypt instead of yassl/taocrypt
- Use HAVE_WOLFSSL instead of HAVE_YASSL
- Increase MY_AES_CTX_SIZE, to avoid compile time asserts in my_crypt.cc
(sizeof(EVP_CIPHER_CTX) is larger on WolfSSL)
