d3f0f5e1c8 Fix check-doxy-blocks.pl to run from root dir
Modify tests/scripts/check-doxy-blocks.pl to ensure that:
  * It can only be run from the mbed TLS root directory.
  * An error code is returned to the environment when a potential error
    in the source code is found.

b8a90fb51c Update ECP hardware abstraction interface
With this commit the Elliptic Curve Point interface is rewised. Two
compile time options has been removed to simplify the interface and
the function names got a new prefix that indicates that these functions
are for internal use and not part of the public interface.

430d3376c9 Add thread safety to ECP hardware acceleration
The intended use of the abstraction layer for Elliptic Curve Point
arithmetic is to enable using hardware cryptographic accelerators.
These devices are a shared resource and the driver code rarely provides
thread safety.

This commit adds mutexes to the abstraction layer to protect the device
in a multi-threaded environment.

552f6b6d17 Add global mutex for asymmetric crypto accelerator
The primary use case behind providing an abstraction layer to enable
alternative Elliptic Curve Point arithmetic implementation, is making
use of cryptographic acceleration hardware if it is present.

To provide thread safety for the hardware accelerator we need a mutex
to guard it.

72849877d0 Fix data loss in unsigned int cast in PK
This patch introduces some additional checks in the PK module for 64-bit
systems only. The problem is that the API functions in the PK
abstraction accept a size_t value for the hashlen, while the RSA module
accepts an unsigned int for the hashlen. Instead of silently casting
size_t to unsigned int, this change checks whether the hashlen overflows
an unsigned int and returns an error.

92e4426169 SSLv3: when refusing renegotiation, stop processing
Before the code was sending a fatal alert but then processing any
further data from the peer.

Internal reference: IOTSSL-1384

c94f7352fa Ignore failures when sending fatal alerts
In many places in TLS handling, some code detects a fatal error, sends
a fatal alert message, and returns to the caller. If sending the alert
fails, then return the error that triggered the alert, rather than
overriding the return status. This effectively causes alert sending
failures to be ignored. Formerly the code was inconsistently sometimes
doing one, sometimes the other.

In general ignoring the alert is the right thing: what matters to the
caller is the original error. A typical alert failure is that the
connection is already closed.

One case which remains not handled correctly is if the alert remains
in the output buffer (WANT_WRITE). Then it won't be sent, or will be
truncated. We'd need to either delay the application error or record
the write buffering notice; to be done later.

1cc8e3472a Send TLS alerts in many more cases
The TLS client and server code was usually closing the connection in
case of a fatal error without sending an alert. This commit adds
alerts in many cases.

Added one test case to detect that we send the alert, where a server
complains that the client's certificate is from an unknown CA (case
tracked internally as IOTSSL-1330).

ports explicitly instead of deriving them from the PID. This
facilitates debugging e.g. with Wireshark.

d1cc7f6f34 Fix buffer overflow in mbedtls_mpi_write_string()
Fix a buffer overflow when writting a string representation of an MPI
number to a buffer in hexadecimal. The problem occurs because hex
digits are written in pairs and this is not accounted for in the
calculation of the required buffer size when the number of digits is
odd.

429aaee671 Remove use of inttypes.h in MSVC from ssl_server2
The sample application programs/ssl/ssl_server2.c was previously
modifies to use inttypes.h to parse a string to a 64-bit integer.
However, MSVC does not support C99, so compilation fails. This
patch modifies the sample app to use the MSVC specific parsing
functions instead of inttypes.h.
