Unify the common parts of mbedtls_dhm_make_params and mbedtls_dhm_make_public.
No intended behavior change, except that the exact error code may
change in some corner cases which are too exotic for the existing unit
tests.

As a result, the copyright of contributors other than Arm is now
acknowledged, and the years of publishing are no longer tracked in the
source files.
Also remove the now-redundant lines declaring that the files are part of
MbedTLS.

In library source files, include "common.h", which takes care of
including "mbedtls/config.h" (or the alternative MBEDTLS_CONFIG_FILE)
and other things that are used throughout the library.

In the next commit, we'll need to draw a second random value, in order to
blind modular inversion. Having a function for that will avoid repetition.

If MBEDTLS_PEM_PARSE_C is unset, the DHM selftest fails because
it uses PEM encoded test data.
This commit fixes this by providing the DER encoded form of the
test data instead in case MBEDTLS_PEM_PARSE_C is unset.
Additional changes to temporarily enable running tests:
ssl_srv.c and test_suite_ecdh use mbedtls_ecp_group_load instead of
mbedtls_ecdh_setup
test_suite_ctr_drbg uses mbedtls_ctr_drbg_update instead of
mbedtls_ctr_drbg_update_ret
This commit removes all the static occurrencies of the function
mbedtls_zeroize() in each of the individual .c modules. Instead the
function has been moved to utils.h that is included in each of the
modules.
This commit returns to using constant macros instead of global variables for the DHM group constants. Further, macros
providing the binary encoding of the primes from RFC 3526 and RFC 7919 are added. The hex-string macros are deprecated.
Although the variable ret was initialised to an error, the
MBEDTLS_MPI_CHK macro was overwriting it. Therefore it ended up being
0 whenewer the bignum computation was successfull and stayed 0
independently of the actual check.
* commit '95f0089':
Update Changelog for DH params
Add test case for dh params with privateValueLength
accept PKCS#3 DH parameters with privateValueLength included
Conflicts:
library/dhm.c
library/dhm.c: accept (and ignore) optional privateValueLength for
PKCS#3 DH parameters.
PKCS#3 defines the ASN.1 encoding of a DH parameter set like this:
----------------
DHParameter ::= SEQUENCE {
prime INTEGER, -- p
base INTEGER, -- g
privateValueLength INTEGER OPTIONAL }
The fields of type DHParameter have the following meanings:
o prime is the prime p.
o base is the base g.
o privateValueLength is the optional private-value
length l.
----------------
See: ftp://ftp.rsasecurity.com/pub/pkcs/ascii/pkcs-3.asc
This optional parameter was added in PKCS#3 version 1.4, released
November 1, 1993.
dhm.c currently doesn't cope well with PKCS#3 files that have this
optional final parameter included. i see errors like:
------------
dhm_parse_dhmfile returned -0x33E6
Last error was: -0x33E6 - DHM - The ASN.1 data is not formatted correctly : ASN1 - Actual length differs from expected lengt
------------
You can generate PKCS#3 files with this final parameter with recent
versions of certtool from GnuTLS:
certtool --generate-dh-params > dh.pem
