This commit starts a migration to a new interface for key creation.
Today, the application allocates a handle, then fills its metadata,
and finally injects key material. The new interface fills metadata
into a temporary structure, and a handle is allocated at the same time
it gets filled with both metadata and key material.
This commit was obtained by moving the declaration of the old-style
functions to crypto_extra.h and renaming them with the to_handle
suffix, adding declarations for the new-style functions in crypto.h
under their new name, and running
perl -i -pe 's/\bpsa_(import|copy|generator_import|generate)_key\b/$&_to_handle/g' library/*.c tests/suites/*.function programs/psa/*.c
perl -i -pe 's/\bpsa_get_key_lifetime\b/$&_from_handle/g' library/*.c tests/suites/*.function programs/psa/*.c
Many functions that are specific to the old interface, and which will
not remain under the same name with the new interface, are still in
crypto.h for now.
All functional tests should still pass. The documentation may have
some broken links.

Programs must not include mbedtls/platform.h if MBEDTLS_PLATFORM_C is
not defined. Test suites don't need to include mbedtls/platform.h
because helpers.function takes care of it.
This commit also removes a stray `;` which is technically not standard C.
Write an all-bits-zero NV seed file for the tests. Without this, if
the seed file is not present when this test suite is executed, the
PSA module initialization will fail, causing most test cases to fail.
Also write an all-bits-zero NV seed file at the end. The test cases in
this test suite mess with the file, but subsequent test suites may
need it.
When testing with custom entropy sources, if MBEDTLS_ENTROPY_NV_SEED
is enabled at compile time but the NV seed source is not used at
runtime, mbedtls_entropy_func makes a second pass anyway. Cope with
this in the test code by telling the entropy module not to make this
second pass.
Add a function to configure entropy sources. For testing only.
Use it to test that the library initialization fails properly if there is no
entropy source.
Allow mbedtls_psa_crypto_free to be called twice, or without a prior
call to psa_crypto_init. Keep track of the initialization state more
precisely in psa_crypto_init so that mbedtls_psa_crypto_free knows
what to do.
