This fixes the following security problems:
* In earlier versions of wolfSSL there exists a potential man in the
middle attack on TLS 1.3 clients.
* Denial of service attack on TLS 1.3 servers from repetitively sending
ChangeCipherSpecs messages. (CVE-2020-12457)
* Potential cache timing attacks on public key operations in builds that
are not using SP (single precision). (CVE-2020-15309)
* When using SGX with EC scalar multiplication the possibility of side-
channel attacks are present.
* Leak of private key in the case that PEM format private keys are
bundled in with PEM certificates into a single file.
* During the handshake, clear application_data messages in epoch 0 are
processed and returned to the application.

Always build AES-GCM support.
Unnecessary patches were removed.
This includes two vulnerability fixes:
CVE-2019-11873: a potential buffer overflow case with the TLSv1.3 PSK
extension parsing.
CVE-2019-13628 (currently assigned-only): potential leak of nonce sizes
when performing ECDSA signing operations. The leak is considered to be
difficult to exploit but it could potentially be used maliciously to
perform a lattice based timing attack.

Removed options that can't be turned off because we're building with
--enable-stunnel, some of which affect hostapd's Config.in.
Adjusted the title of OCSP option, as OCSP itself can't be turned off,
only the stapling part is selectable.
Mark options turned on when wpad support is selected.
Add building options for TLS 1.0, and TLS 1.3.
Add hardware crypto support, which due to a bug, only works when CCM
support is turned off.
Reorganized option conditionals in Makefile.
Add Eneas U de Queiroz as maintainer.

This includes a fix for a medium-level potential cache attack with a
variant of Bleichenbacher’s attack. Patches were refreshed.
Increased FP_MAX_BITS to allow 4096-bit RSA keys.
Fixed poly1305 build option, and some Makefile updates.

Use download from github archive corresponding to v3.14.4 tag because
the project's website apparently only offers 3.14.0-stable release
downloads.

This seems to cause a false-positive warning/error
while building `libwebsockets-cyassl`.

```
Hardening is enabled by default in libwolfssl at build-time.
However, the `settings.h` header is exported (along with other headers)
for build (via Build/InstallDev).
This looks like a small bug/issue with wolfssl.
