Disable MBEDTLS_SHA256_SMALLER implementation, not enabled by default in
upstream and reduces performance by quite a bit.
Source: include/mbedtls/config.h
Enable an implementation of SHA-256 that has lower ROM footprint but also
lower performance.
The default implementation is meant to be a reasonnable compromise between
performance and size. This version optimizes more aggressively for size at
the expense of performance. Eg on Cortex-M4 it reduces the size of
mbedtls_sha256_process() from ~2KB to ~0.5KB for a performance hit of
about 30%.
The size of mbedtls increased a little bit:
ipkg for mips_24kc before:
164.382 Bytes
ipkg for mips_24kc after:
166.240 Bytes

Update mbed TLS to 2.11.0
Disable OFB block mode and XTS block cipher mode, added in 2.11.0.
The soVersion of mbedtls changed, bump PKG_RELEASE for packages that use mbedTLS
This is to avoid having a mismatch between packages when upgrading.
The size of mbedtls increased a little bit:

This makes mbedtls use the POSIX API directly and not use the own
abstraction layer.
The size of the ipkg decreased by about 100 bytes.

This make sit possible to store informations about a session and reuse
it later. When used by a server it increases the time to create a new
TLS session from about 1 second to less than 0.1 seconds.
The size of the ipkg file increased by about 800 Bytes.

The soversion was changed in this version again and is now aligned with
the 2.7.2 version.
The size of the ipkg file stayed mostly the same.

Fixed an authentication bypass issue in SSL/TLS. When the TLS
authentication mode was set to 'optional',
mbedtls_ssl_get_verify_result() would incorrectly return 0 when the
peer's X.509 certificate chain had more than
MBEDTLS_X509_MAX_INTERMEDIATE_CA intermediates (default: 8), even when
it was not trusted. This could be triggered remotely on both the client
and server side. (Note, with the authentication mode set by
mbedtls_ssl_conf_authmode()to be 'required' (the default), the handshake
was correctly aborted).

Fixes some security issues (no remote exploits), and introduces
some changes. See release notes for details:
https://tls.mbed.org/tech-updates/releases/mbedtls-2.5.1-2.1.8-and-1.3.20-released
* Fixes an unlimited overread of heap-based buffers in mbedtls_ssl_read()
* Adds exponent blinding to RSA private operations
* Wipes stack buffers in RSA private key operations (rsa_rsaes_pkcs1_v15_decrypt(), rsa_rsaes_oaep_decrypt())
* Removes SHA-1 and RIPEMD-160 from the default hash algorithms for certificate verification.
* Fixes offset in FALLBACK_SCSV parsing that caused TLS server to fail to detect it sometimes.
* Tighten parsing of RSA PKCS#1 v1.5 signatures, to avoid a potential Bleichenbacher/BERserk-style attack.

Later OpenVPN 2.3-openssl versions only enable
TLS cipher suites with perfect forward secrecy, i.e. DHE and ECDHE
cipher suites. ECDHE key exchange is not supported by
OpenVPN 2.3-openssl, enable DHE key exchange to allow LEDE
OpenVPN 2.4-mbedtls clients to connect to such servers.

Secp384r1 is the default curve for OpenVPN 2.4+. Enable this to

This option is required by OpenVPN, and OpenVPN 2.4 uses mbedTLS 2.x.

luci using ustream-mbedtls is extremely slow vs ustream-polarssl.
polarssl alias mbedtls v1 is configured to use NIST prime speed
optimisation, so no longer disable the default optimisation for
mbedtls v2.
