815e9a21a3 Remove files sourced from Mbed Crypto
Remove cryptography related files and a few utility header files that
are shared between Mbed TLS and Mbed Crypto. Mbed TLS will use an Mbed
Crypto sourced version of each of these header files in order to ease
the maintenance burden of both libraries, and to make it easier to keep
Mbed TLS and Mbed Crypto in sync.

As part of removing cryptography related files, tell Doxygen to source
information from the removed the headers, so that it will consider them
for inclusion within Doxygen output.

Later, as part of the Mbed TLS 3.0 (API breaking version), we'll
restructure the organization of the 3 libraries a bit, to move some
things out of Mbed Crypto that don't belong there.

Candidates of not belonging in Mbed Crypto, but are in libmbedcrypto.so
for legacy reasons:
 - asn1.h
 - asn1write.h
 - base64.h
 - memory_buffer_alloc.h
 - platform.h
 - platform_time.h
 - platform_util.h
 - threading.h
 - timing.h
 - version.h

6609aef809 Use mbedtls-based path for includes
To help the build system find the correct include files, paths starting
with "mbedtls/" or "psa/" must be used. Otherwise, you can run into
build failures like the following when building Mbed Crypto as a
submodule.

    In file included from chachapoly.c:31:0:
    ../../include/mbedtls/chachapoly.h:43:10: fatal error: poly1305.h: No such file or directory

47be7686ab Make mbedtls_ssl_in_hdr_len() CID-unaware
The function mbedtls_ssl_in_hdr_len() is supposed to return the length
of the record header of the current incoming record. With the advent
of the DTLS Connection ID, this length is only known at runtime and
hence so far needed to be derived from the internal in_iv pointer
pointing to the beginning of the payload of the current incooing
record.

By now, however, those uses of mbedtls_ssl_in_hdr_len() where the
presence of a CID would need to be detected have been removed
(specifically, ssl_parse_record_header() doesn't use it anymore
when checking that the current datagram is large enough to hold
the record header, including the CID), and it's sufficient to
statically return the default record header sizes of 5 / 13 Bytes
for TLS / DTLS.

5daa34f155 bn_mul.h: require at least ARMv6 to enable the ARM DSP code
Commit 16b1bd8932 "bn_mul.h: add ARM DSP optimized MULADDC code"
added some ARM DSP instructions that was assumed to always be available
when __ARM_FEATURE_DSP is defined to 1. Unfortunately it appears that
the ARMv5TE architecture (GCC flag -march=armv5te) supports the DSP
instructions, but only in Thumb mode and not in ARM mode, despite
defining __ARM_FEATURE_DSP in both cases.

This patch fixes the build issue by requiring at least ARMv6 in addition
to the DSP feature.

f3820e36f7 Fix misuse of signed ints in the HAVEGE module
Update havege.h to the new version in the crypto module.

This is technically an API break, since the type mbedtls_havege_state
is exposed in a public header. However normal applications should not
be affected.

There is no ABI break on platforms where uint32_t and int are treated
identically, which is virtually all of them.

c7ad122f51 Make it easier to define MBEDTLS_PARAM_FAILED as assert
Introduce a new configuration option MBEDTLS_CHECK_PARAMS_ASSERT,
which is disabled by default. When this option is enabled,
MBEDTLS_PARAM_FAILED defaults to assert rather than to a call to
mbedtls_param_failed, and <assert.h> is included.

This fixes #2671 (no easy way to make MBEDTLS_PARAM_FAILED assert)
without breaking backward compatibility. With this change,
`config.pl full` runs tests with MBEDTLS_PARAM_FAILED set to assert,
so the tests will fail if a validation check fails, and programs don't
need to provide their own definition of mbedtls_param_failed().

960e588278 Document origin of hardcoded certificates in library/certs.c
All of them are copied from (former) CRT and key files in `tests/data_files`.
For files which have been regenerated since they've been copied to `certs.c`,
update the copy.

Add declarations for DER encoded test CRTs to certs.h

Add DER encoded versions of CRTs to certs.c

fix comment in certs.c

Don't use (signed) char for DER encoded certificates

Consistently use `const char *` for test CRTs regardless of encoding

Remove non-sensical and unused PW variable for DER encoded key

Provide test CRTs in PEM and DER fmt, + pick suitable per config

This commit modifies `certs.h` and `certs.c` to start following the
following pattern for the provided test certificates and files:

- Raw test data is named `NAME_ATTR1_ATTR2_..._ATTRn`

  For example, there are
     `TEST_CA_CRT_{RSA|EC}_{PEM|DER}_{SHA1|SHA256}`.

- Derived test data with fewer attributes, iteratively defined as one
  of the raw test data instances which suits the current configuration.

  For example,
     `TEST_CA_CRT_RSA_PEM`
  is one of `TEST_CA_CRT_RSA_PEM_SHA1` or `TEST_CA_CRT_RSA_PEM_SHA256`,
  depending on whether SHA-1 and/or SHA-256 are defined in the current
  config.

Add missing public declaration of test key password

Fix signedness and naming mismatches

Further improve structure of certs.h and certs.c

Fix definition of mbedtls_test_cas test CRTs depending on config

Remove semicolon after macro string constant in certs.c

615ef17b67 Allow passing NULL pointers to mbedtls_ssl_get_peer_cid()
This commit modifies mbedtls_ssl_get_peer_cid() to also allow passing
NULL pointers in the arguments for the peer's CID value and length, in
case this information is needed.

For example, some users might only be interested in whether the use of
the CID was negotiated, in which case both CID value and length pointers
can be set to NULL. Other users might only be interested in confirming
that the use of CID was negotiated and the peer chose the empty CID,
in which case the CID value pointer only would be set to NULL.
It doesn't make sense to pass a NULL pointer for the CID length but a
non-NULL pointer for the CID value, as the caller has no way of telling
the length of the returned CID - and this case is therefore forbidden.

c37c96a3c5 Add specific SSL error code for unexpected CIDs
Currently, the stack silently ignores DTLS frames with an unexpected CID.
However, in a system which performs CID-based demultiplexing before passing
datagrams to the Mbed TLS stack, unexpected CIDs are a sign of something not
working properly, and users might want to know about it.

This commit introduces an SSL error code MBEDTLS_ERR_SSL_UNEXPECTED_CID
which the stack can return in response to an unexpected CID. It will
conditionally be put to use in subsequent commits.
