When generating .c files from .function files, add #line directives so
that errors in the generated files are reported with the correct line
number. Also add #line directives to the template .function files, for
the same reason.
This is a backport of things that got added later than 2.1 in several stages.
The change in the truncated HMAC extension aligns Mbed TLS with the
standard, but breaks interoperability with previous versions. Indicate
this in the ChangeLog, as well as how to restore the old behavior.
Add mbedTLS.vcxproj to the VS2010 application template so that the next
time we auto-generate the application project files, the
LinkLibraryDependencies for mbedTLS.vcxproj are maintained.
Fixes#1347
Extend the pkparse test suite with the newly created keys
encrypted using PKCS#8 with PKCS#5 v2.0 with PRF being
SHA224, 256, 384 and 512.

We now have support for the entire SHA family to be used as
PRF in PKCS#5 v2.0, therefore we need to add new keys to test
these new functionalities.
This patch adds the new keys in `tests/data_files` and
commands to generate them in `tests/data_files/Makefile`.
Note that the pkcs8 command in OpenSSL 1.0 called with
the -v2 argument generates keys using PKCS#5 v2.0 with SHA1
as PRF by default.
(This behaviour has changed in OpenSSL 1.1, where the exact same
command instead uses PKCS#5 v2.0 with SHA256)
The new keys are generated by specifying different PRFs with
-v2prf.

Some unit tests for pbkdf2_hmac() have results longer than
99bytes when represented in hexadecimal form.
For this reason extend the result array to accommodate
longer strings.
At the same time make memset() parametric to avoid
bugs in the future.

Test vectors for SHA224,256,384 and 512 have been
generated using Python's hashlib module by the
following oneliner:
import binascii, hashlib
binascii.hexlify(hashlib.pbkdf2_hmac(ALGO, binascii.unhexlify('PASSWORD'), binascii.unhexlify('SALT'), ITER, KEYLEN)))
where ALGO was 'sha224', 'sha256', 'sha384' and 'sha512'
respectively.
Values for PASSWORD, SALT, ITER and KEYLEN were copied from the
existent test vectors for SHA1.
For SHA256 we also have two test vectors coming from RFC7914 Sec 11.

Currently only SHA1 is supported as PRF algorithm for PBKDF2
(PKCS#5 v2.0).
This means that keys encrypted and authenticated using
another algorithm of the SHA family cannot be decrypted.
This deficiency has become particularly incumbent now that
PKIs created with OpenSSL1.1 are encrypting keys using
hmacSHA256 by default (OpenSSL1.0 used PKCS#5 v1.0 by default
and even if v2 was forced, it would still use hmacSHA1).
Enable support for all the digest algorithms of the SHA
family for PKCS#5 v2.0.

MD2, MD4, MD5, DES and SHA-1 are considered weak and their use
constitutes a security risk. If possible, we recommend avoiding
dependencies on them, and considering stronger message digests and
ciphers instead.
