45778acf85 Resource leak fix on windows platform
Fix a resource leak on windows platform, in mbedtls_x509_crt_parse_path,
in case a failure. when an error occurs, goto cleanup, and free the
resource, instead of returning error code immediately.

1d74c41a49 Remove mutexes from ECP hardware acceleration
Protecting the ECP hardware acceleratior with mutexes is inconsistent with the
philosophy of the library. Pre-existing hardware accelerator interfaces
leave concurrency support to the underlying platform.

122d899296 Add library setup and teardown APIs
Add the following two functions to allow platform setup and teardown
operations for the full library to be hooked in:

* mbedtls_platform_setup()
* mbedtls_platform_teardown()

An mbedtls_platform_context C structure is also added and two internal
functions that are called by the corresponding setup and teardown
functions above:

* mbedtls_internal_platform_setup()
* mbedtls_internal_plartform_teardown()

Finally, the macro MBEDTLS_PLATFORM_SETUP_ALT is also added to allow
mbedtls_platform_context and internal function to be overriden by the
user as needed for a platform.

489b985fae Export mbedtls_aes_(en/de)crypt to retain for API compatibility
The commit f5bf7189d3 made the AES
functions mbedtls_aes_encrypt and mbedtls_aes_decrypt static, changing
the library's API.

This commit reverts this.

649dcab175 Clarify documentation for alternative AES implementations
The functions mbedtls_aes_decrypt and mbedtls_aes_encrypt have been
superseded by mbedtls_aes_internal_decrypt and
mbedtls_aes_internal_encrypt, respectively. Alternative
implementations should now only replace the latter, and leave the
maintenance wrapper definitions of the former untouched.

This commit clarifies this in the documentation of the respective
configuration options MBEDTLS_AES_DECRYPT_ALT and
MBEDTLS_AES_ENCRYPT_ALT.

0a38f1ac28 Undo API change from SHA1 deprecation
The previous commit bd5ceee484f201b90a384636ba12de86bd330cba removed
the definition of the global constants
- mbedtls_test_ca_crt_rsa_len,
- mbedtls_test_cli_crt_rsa_len,
- mbedtls_test_ca_crt_rsa, and
- mbedtls_test_cli_crt_rsa.
This commit restores these to maintain ABI compatibility.

Further, it was noticed that without SHA256_C being enabled the
previous code failed to compile because because the SHA1 resp. SHA256
certificates were only defined when the respective SHAXXX_C options
were set, but the emission of the global variable mbedtls_test_ca_crt
was unconditionally defined through the SHA256
certificate. Previously, the RSA SHA1 certificate was unconditionally
defined and used for that.

As a remedy, this commit makes sure some RSA certificate is defined
and exported through the following rule:
1. If SHA256_C is active, define an RSA SHA256 certificate and export
   it as mbedtls_test_ca_crt. Also, define SHA1 certificates only if
   SHA1_C is set.
2. If SHA256_C is not set, always define SHA1 certificate and export
   it as mbedtls_test_ca_crt.

d15795acd5 Improve behaviour on fatal errors
If we didn't walk the whole chain, then there may be any kind of errors in the
part of the chain we didn't check, so setting all flags looks like the safe
thing to do.

1beb048316 Add test for limit on intermediate certificates
Inspired by test code provided by Nicholas Wilson in PR #351.

The test will fail if someone sets MAX_INTERMEDIATE_CA to a value larger than
18 (default is 8), which is hopefully unlikely and can easily be fixed by
running long.sh again with a larger value if it ever happens.

Current behaviour is suboptimal as flags are not set, but currently the goal
is only to document/test existing behaviour.

bdf3905fff Ensure application data records are not kept when fully processed
This commit fixes the following case: If a client is both expecting a
SERVER_HELLO and has an application data record that's partially
processed in flight (that's the situation the client gets into after
receiving a ServerHelloRequest followed by ApplicationData), a
subsequent call to mbedtls_ssl_read will set keep_current_message = 1
when seeing the unexpected application data, but not reset it to 0
after the application data has been processed. This commit fixes this.

It also documents and suggests how the problem might be solved in a
more structural way on the long run.
