- Add an --enable-rsyslog option to configure.ac.
- Add a few missing `WOLFSSL_ERROR` calls that were expected by rsyslog unit
tests.
- Add better documentation around `WOLFSSL_SHUTDOWN_NOT_DONE` and define it to
be 0 (rather than 2) when `WOLFSSL_ERROR_CODE_OPENSSL` is defined. This is in
accordance with OpenSSL documentation. Without this change, rsyslog was
failing to do the bidirectional shutdown properly because it was checking the
shutdown return value against 0. I'm keeping the old value when
`WOLFSSL_ERROR_CODE_OPENSSL` isn't defined because it's part of the public
wolfssl interface (it's in ssl.h).
- Handle case where output buffer is NULL. In this case, passed in output buffer
length pointer should be given the maximum output buffer size needed.
- Add better debug messages.

# Other Changes
- Ignore gdbinit
- Add api.c tests for new API
- Add `WOLFSSL_X509_STORE* x509_store_pt` to `WOLFSSL`
- Add macro to select the `WOLFSSL` specific store when available and the associated `WOLFSSL_CTX` store otherwise. Calls to `ssl->ctx->cm` and `ssl->ctx->x509_store*` were replaced by macros.
- NO-OP when setting existing store
- Add reference counter to `WOLFSSL_X509_STORE`
- Cleanup MD5 redundant declarations
- WOLFSSL_ERROR may map to nothing so make assignment outside of it
- refMutex fields are excluded with SINGLE_THREADED macro
- Chain cert refactor
- Make `wolfSSL_add0_chain_cert` and `wolfSSL_add1_chain_cert` not affect the context associated with the SSL object
- `wolfSSL_CTX_add1_chain_cert` now updates the `ctx->certChain` on success and stores the cert in `ctx->x509Chain` for later free'ing
pyOpenSSL needs the OpenSSL function X509_EXTENSION_dup, so this commit adds
that to the compatibility layer. It also needs to be able to access the DER
encoding of the subject alt names in a cert, so that's added as well.
