91d7938761 Changed every memcpy to SCA equivalent mbedtls_platform_memcpy 
This makes physical attacks more difficult.

7a346b866c Replace memset() with mbedtls_platform_memset() 
Steps:

1. sed -i 's/\bmemset(\([^)]\)/mbedtls_platform_memset(\1/g' library/*.c tinycrypt/*.c include/mbedtls/*.h scripts/data_files/*.fmt

2. Manually edit library/platform_util.c to revert to memset() in the
implementations of mbedtls_platform_memset() and mbedtls_platform_memcpy()

3. egrep -n '\<memset\>' library/*.c include/mbedtls/*.h tinycrypt/*.c
The remaining occurrences are in three categories:
    a. From point 2 above.
    b. In comments.
    c. In the initialisation of memset_func, to be changed in a future commit.

e32df087fb Remove individual copies of mbedtls_zeroize() 
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.

9cf1f96a7b Fix corner case uses of memory_buffer_alloc.c 
The corner cases fixed include:
    * Allocating a buffer of size 0. With this change, the allocator now
      returns a NULL pointer in this case. Note that changes in pem.c and
      x509_crl.c were required to fix tests that did not work under this
      assumption.
    * Initialising the allocator with less memory than required for headers.
    * Fix header chain checks for uninitialised allocator.

9e4f77c606 New MD API: rename functions from _ext to _ret 
The _ext suffix suggests "new arguments", but the new functions have
the same arguments. Use _ret instead, to convey that the difference is
that the new functions return a value.

d91f2a26cb Merge branch 'development' into iotssl-1251-2.7 
Conflict resolution:

* ChangeLog: put the new entries in their rightful place.
* library/x509write_crt.c: the change in development was whitespace
  only, so use the one from the iotssl-1251 feature branch.

Update after Andres coments:
1. zeroize the buffer in `mbedtls_pem_read_buffer()` before freeing it
2. use `mbedtls_zeroize()` instead of `memset()`

51a7ae1353 Add missing ret code checks in PEM module 
Add missing return code checks in the functions pem_des_decrypt(),
pem_3des_decrypt() and pem_aes_decrypt() so that the calling function
mbedtls_pem_read_buffer() is notified of errors reported by the crypto
primitives AES, DES and 3DES.
