dfb6015ca7 Implements AES and GCM with ARMv8 Crypto Extensions
A compact patch that provides AES and GCM implementations that utilize the
ARMv8 Crypto Extensions. The config flag is MBEDTLS_ARMV8CE_AES_C, which
is disabled by default as we don't do runtime checking for the feature.
The new implementation lives in armv8ce_aes.c.

Provides similar functionality to https://github.com/ARMmbed/mbedtls/pull/432
Thanks to Barry O'Rourke and others for that contribtion.

Tested on a Cortex A53 device and QEMU. On a midrange phone the real AES-GCM
throughput increases about 4x, while raw AES speed is up to 10x faster.

When cross-compiling, you want to set something like:

  export CC='aarch64-linux-gnu-gcc'
  export CFLAGS='-Ofast -march=armv8-a+crypto'
  scripts/config.pl set MBEDTLS_ARMV8CE_AES_C

QEMU seems to also need

  export LDFLAGS='-static'

Then run normal make or cmake etc.

6240defd17 Add MBEDTLS_TEST_CONSTANT_FLOW_MEMSAN
This option allows to test the constant-flow nature of selected code, using
MemSan and the fundamental observation behind ctgrind that the set of
operations allowed on undefined memory by dynamic analysers is the same as the
set of operations allowed on secret data to avoid leaking it to a local
attacker via side channels, namely, any operation except branching and
dereferencing.

(This isn't the full story, as on some CPUs some instructions have variable
execution depending on the inputs, most notably division and on some cores
multiplication. However, testing that no branch or memory access depends on
secret data is already a good start.)

de8593f2fe Implement and test mbedtls_ecp_write_key
mbedtls_ecp_write_key is a mirror function to mbedtls_ecp_read_key, which
writes a private key back into a byte buffer in the correct format.
This is a helpful convenience function, since the byte order is defined
differently between Montgomery and Weierstrass curves. Since this difference
is accounted for in mbedtls_ecp_read_key, it made sense to add
mbedtls_ecp_write_key for the purpose of abstracting this away such that
psa_export_key doesn't need to take byte order into account.

c52a43c2bd Implement use of internal DRBG for ecp_mul()
The case of MBEDTLS_ECP_RESTARTABLE isn't handled correctly yet: in that case
the DRBG instance should persist when resuming the operation. This will be
addressed in the next commit.

When both CTR_DRBG and HMAC_DRBG are available, CTR_DRBG is preferred since
both are suitable but CTR_DRBG tends to be faster and I needed a tie-breaker.

There are currently three possible cases to test:

- NO_INTERNAL_RNG is set -> tested in test_ecp_no_internal_rng
- it's unset and CTR_DRBG is available -> tested in the default config
- it's unset and CTR_DRBG is disabled -> tested in
  test_ecp_internal_rng_no_ctr_drbg
