41dba28a2a Add extra compilation conditions to gen_key.c #559 
The sample application programs/pkey/gen_key.c uses the library function
mbedtls_pk_write_key_pem() which is dependent on the configuration option
MBEDTLS_PEM_WRITE_C. If the option isn't defined the build breaks.

This change adds the compilation condition MBEDTLS_PEM_WRITE_C to the gen_key.c
sample application.

0c79073a8b Refactor and change CMAC interface 
Change the CMAC interface to match the mbedtls_md_hmac_xxxx() interface. This
changes the overall design of the CMAC interface to make it more consistent with
the existing HMAC interface, and will allow incremental updates of input data
rather than requiring all data to be presented at once, which is what the
current interface requires.

59ae4bad18 cmac: some more padding-related tune-ups 
- use one less temporary buffer
- pedantic: in_len + 15 was a potential overflow
- use a more explicit name instead of 'flag'
- Mn was a bit misleading

89b8d83723 cmac: make subkey gen more constant-time 
The previous version had secret-dependent memory accesses. While it was
probably not an issue in practice cause the two bytes of the array are
probably on the same cache line anyway, as a matter of principle this should
be avoided.
