* sverk/crypto-ec-mem-leak/OTP-11999:
  crypto: Fix memory leak of EC "keys" and "points"
  crypto: Fix crypto for debug and valgrind

without relying on opt-version has been built.

Removed ASSERT to make crypto_callback.debug.so work without
dynamic linking to libcrypto.so.

* pguyot/fix_srp:
  Fix bug in SRP implementation

sign(dss,) and compute_key(dh,)

The context was never deallocated.

SRP didn't work with smaller primes as user secret was improperly
computed.

Formula is: (B - (k * g^x)) ^ (a + (u * x)) % N

Previously, the code computed a + (u * x) % N instead of a + (u * x).
a typically is a 256 bits random number (RFC 5054 says it should be at
least 256 bits), u and x are SHA1 signatures (160 bits). So a + (u * x)
can differ from a + (u * x) % N for N primes smaller than 320 bits.

This adds the aes_cfb8 cypher type (and associated tests and
documentation) to the crypto module.
