This helps to prevent confusion as it avoids overloading the word
"copy" as both an action and an object.

When we are copying output, it makes sense to return
PSA_ERROR_BUFFER_TOO_SMALL since the buffer we are copying to is a user
output buffer.

Change psa_crypto_output_copy_free() to use psa_crypto_copy_output()
rather than calling memcpy directly as was erroneously done previously.

This includes:
* The psa_crypto_input_copy_t struct
* psa_crypto_input_copy_alloc()
* psa_crypto_input_copy_free()

This tied input and output buffers together in
awkward pairs, which made the API more difficult
to use.

Since we are internal rather than user-facing,
PSA_ERROR_CORRUPTION_DETECTED makes more sense than
PSA_ERROR_BUFFER_TOO_SMALL. Whilst it really is a buffer that is too
small, this error code is intended to indicate that a user-supplied
buffer is too small, not an internal one.

Zero-length buffers should be represented in the
psa_crypto_buffer_copy_t struct as NULL if it was created in
psa_crypto_alloc_and_copy(), so reject non-NULL zero-length buffers.

If we have a copy buffer but no original to copy back to, there is not
much sensible we can do. The psa_crypto_buffer_copy_t state is invalid.

Since it is implementation-dependent whether
malloc(0) returns NULL or a pointer, explicitly
represent zero-length buffers as NULL in the
buffer-copy struct, so as to have a uniform
behaviour.

Add function prototypes for psa_crypto_alloc_and_copy() and
psa_crypto_alloc_and_free(), along with the necessary state struct.

This changes local variable name RCON to round_constants.
RCON being definition in xc32 compiler headers for some PIC32 register.
Without this change, mynewt project for PIC32 platform fails to build due to
macro redefinition.
This does not changes behavior of library in any way.

In PSA headers include psa/build_info.h instead
of mbedtls/build_info.h. In Mbed TLS, both are
equivalent but not in TF-PSA-Crypto where
psa/build_info.h is the correct one.
