Gilles Peskine 33c92f01a0 Determine MBEDTLS_ECP_MAX_BITS automatically
MBEDTLS_ECP_MAX_BITS is now determined automatically from the configured
curves and no longer needs to be configured explicitly to save RAM. Setting
it explicit in config.h is still supported for backward compatibility.

Security
* It was possible to configure MBEDTLS_ECP_MAX_BITS to a value that is
too small, leading to buffer overflows in ECC operations. Fail the build
in such a case.
Features
* MBEDTLS_ECP_MAX_BITS is now determined automatically from the configured
curves and no longer needs to be configured explicitly to save RAM.
