### Description
This PR moves the old memap file handling required for differential
memap from within memap to the toolchain object. This has the
advantage that we can do the `mv <app>.map <app>.map.old` the moment
before it is overwritten by the linker. This should allow multiple
reruns of memap without modifying your build directory.

Return `MBEDTLS_ERR_AES_FEATURE_UNAVAILABLE` only for valid key lengths,
that are not supported by Cryptocell 310. For other key sizes, return
`MBEDTLS_ERR_CCM_BAD_INPUT`
1. Change camelcase variables to Mbed OS style.
2. Remove functions declarations from the `_alt` header, since they
are now added from the module header regardless whether an alternative
implementation exists.
3. Remove the `extern "c"` declaration from the `_alt` headers.
4. Remove whitespaces before opening parenthesis.
5. Fix alignment of function parameters.
6. Fix indentations.
7. Limit lines to 80 characters.
Return `MBEDTLS_ERR_ECP_INVALID_KEY` when Cryptocell returns
`CRYS_ECPKI_BUILD_KEY_INVALID_PRIV_KEY_SIZE_ERROR`
or `CRYS_ECPKI_BUILD_KEY_INVALID_PUBL_KEY_SIZE_ERROR`,
When the key size is invalid. Found by the "ECDSA zero private parameter"
tests.
An additional fix for ccm_alt, when the message length is too big.
Check for specific error returned from CC310, and return
`MBEDTLS_ERR_CCM_BAD_INPUT`.
Currently there are two issues which prevent building Mbed OS with
-std=gnu++11 when using Arm Compiler 6:
* NanostackRfPhys2lp.cpp contains a narrowing conversion in a braced
initializer list
* ns_types.h includes <stdalign.h> which Arm Compiler 6 currently
does not provide
This patch fixes both issues. The first one is fixed by changing the
underlying type of the corresponding enumeration when the code is
compiled as C++11. The second issue is worked around by avoiding the
use of <stdalign.h> header for Arm Compiler versions prior to 6.12.
