9bb5effc32 ecp: Add support for hardware implementation of ECP routines 
ESP32C2 has a hardware ECC accelerator that supports NIST P-192 and NIST P-256 curves,
which can increase the performance of the point multiplication and point
verification operation.

Provision is also added to fallback to software implementation in
case the curve is not from the supported curves

70fc9eb89c bignum: add provision for combined software and hardware MPI approach 
For exponential mod (API mbedtls_mpi_exp_mod) operation, some ESP target
chips needs to have ability for both hardware and software implementation.

Hardware implementation provided performance advantage but it can only
support upto 3072 bit operations (e.g., ESP32-C3) and hence we fallback
to software implementation in such cases (e.g., 4096 bit operations).

Earlier this was handled using linker "--wrap" flag but that does not
work in all scenarios as API `mbedtls_mpi_exp_mod` is being used in
same tranlation (compilation unit).

This approach was found to be next best option with minimal changes in
mbedTLS library.

46d3be2866 Make CMakeLists.txt discover if mbed TLS is being built as subproject 
The main CMakeLists.txt is capable to detect if it's being built as
a subproject (i.e. through add_subdirectory()) hence allowing to
disable the package configuration, target export and installation
that generally are not required when mbed TLS is being built as
part of another project.

12e27d4c5b List ssl_debug_helpers_generated.h in generated files 
Running `generate_ssl_debug_helpers.py` generates both
`ssl_debug_helpers_generated.c` and `ssl_debug_helpers_generated.h`.

List the `.h` file as well as the `.c` file in `check-generated-files.sh` so
that `check-generated-files.sh -u` will complain if it isn't up to date.

List it in `Makefile` and `CMakeLists.txt` so that parallel builds know when
to wait until the `.h` file is present. In `Makefile`, declare the `.c` file
as depending on the `.h` file for order. This way, a dependency for either
will wait until the `.h` file is present, and since the `.h` file is
generated after the `.c` file, this guarantees that the `.c` file is
present.

This fixes random failures of `make -j` from a fresh checkout.

d5ba50e239 Zeroize local MAC variables 
Zeroize local MAC variables used for CBC+HMAC cipher suites. In encryption,
this is just good hygiene but probably not needed for security since the
data protected by the MAC that could leak is about to be transmitted anyway.
In DTLS decryption, this could be a security issue since an adversary could
learn the MAC of data that they were trying to inject. At least with
encrypt-then-MAC, the adversary could then easily inject a datagram with
a corrected packet. TLS would still be safe since the receiver would close
the connection after the bad MAC.

6e7deb1d55 Add expected output for tests 
Expected output generated by OpenSSL (see below) apart from the case
where both password and salt are either NULL or zero length, as OpenSSL
does not support this. For these test cases we have had to use our own
output as that which is expected. Code to generate test cases is as
follows:

 #include <openssl/pkcs12.h>
 #include <openssl/evp.h>
 #include <string.h>

                                    *md_type )
{
   size_t index;

   printf( "%s\n", test_name );

   int ret = PKCS12_key_gen_uni( pass, passlen, salt, saltlen, id, iter,
                                        n, out, md_type );

   if( ret != 1 )
   {
         printf( "Key generation returned %d\n", ret );
      }
   else
   {
         for( index = 0; index < n; ++index )
         {
                  printf( "%02x", out[index] );
               }

         printf( "\n" );
      }

   printf( "\n" );

}
