26e4fdc6cd Move MEMORY_BUFFER_ALLOC components to align the order with mbedtls
No code change. This commit just moves two functions to make the order
of component definitions match the one in mbedtls.

9bbe328752 Test each failure mode of pk_parse_key_pkcs1_der()
(Only the top-level ones, ie, for each call to eg asn1_get_mpi(), ensure
there's at least one test case that makes this call fail in one way, but don't
test the various ways to make asn1_get_mpi fail - that should be covered
elsewhere.)

- the new checks added by the previous commits needed exercising
- existing tests sometimes had wrong descriptions or where passing for the
  wrong reason (eg with the "length mismatch" test, the function actually
failed before reaching the length check)
- while at it, add tests for the rest as well

The valid minimal-size key was generated with:

openssl genrsa 128 2>/dev/null | openssl rsa -outform der 2>/dev/null | xxd -p

  correct run-time dependency information)

Individual files with conflicts:

* `README.md`: keep the crypto version.
* `doxygen/input/doc_mainpage.h`: keep the crypto version (with an obsolete Mbed Crypto version number).
* `include/mbedtls/error.h`:
    * `ERROR`: similar additions made through parallel commits, with only whitespace differences. Align with the tls version.
* `library/CMakeLists.txt`: keep the crypto version.
* `library/Makefile`: keep the crypto version.
* `scripts/generate_errors.pl`: keep the crypto version (the relevant changes were made through parallel commits).
* `tests/scripts/check-test-cases.py`:
    * `Results`: keep the crypto version, which has both the new argument to the constructor (added in crypto only) and the class docstring (added through parallel commits).
* `tests/suites/helpers.function`:
    * `ARRAY_LENGTH`, `ASSERT_ALLOC`: additions in the same location. Keep both, in indifferent order.
* `tests/suites/target_test.function`:
    * `receive_uint32`: keep the crypto version which has an additional bug fix. The tls changes made in tls are irrelevant after this bug fix.
* `visualc/VS2010/mbedTLS.vcxproj`: run `scripts/generate_visualc_files.pl`.

Review of non-conflicting changes:

* `all.sh`: 1 change.
    * zlib test components: don't add them.

7cfcb3fc03 Change the encoding of key types to have a parity bit
Change the encoding of key types, EC curve families and DH group
families to make the low-order bit a parity bit (with even parity).

This ensures that distinct key type values always have a Hamming
distance of at least 2, which makes it easier for implementations to
resist single bit flips.

f65ed6f254 Change key types to a 16-bit encoding
All key types now have an encoding on 32 bits where the bottom 16 bits
are zero. Change to using 16 bits only.

Keep 32 bits for key types in storage, but move the significant
half-word from the top to the bottom.

Likewise, change EC curve and DH group families from 32 bits out of
which the top 8 and bottom 16 bits are zero, to 8 bits only.

Reorder psa_core_key_attributes_t to avoid padding.

b87b719467 Remove old values of curve encodings
Remove the values of curve encodings that are based on the TLS registry
and include the curve size, keeping only the new encoding that merely
encodes a curve family in 8 bits.

Keep the old constant names as aliases for the new values and
deprecate the old names.

228abc5773 Define EC curve family constants
Define constants for ECC curve families and DH group families. These
constants have 0x0000 in the lower 16 bits of the key type.

Support these constants in the implementation and in the PSA metadata
tests.

Switch the slot management and secure element driver HAL tests to the
new curve encodings. This requires SE driver code to become slightly
more clever when figuring out the bit-size of an imported EC key since
it now needs to take the data size into account.

Switch some documentation to the new encodings.

Remove the macro PSA_ECC_CURVE_BITS which can no longer be implemented.

025fccdc32 Change the encoding of EC curves and DH groups to include the size
Change the representation of psa_ecc_curve_t and psa_dh_group_t from
the IETF 16-bit encoding to a custom 24-bit encoding where the upper 8
bits represent a curve family and the lower 16 bits are the key size
in bits. Families are based on naming and mathematical similarity,
with sufficiently precise families that no two curves in a family have
the same bit size (for example SECP-R1 and SECP-R2 are two different
families).

As a consequence, the lower 16 bits of a key type value are always
either the key size or 0.

4295e8b9c5 Rework PSA curve to mbedlts group id conversion
Don't rely on the bit size encoded in the PSA curve identifier, in
preparation for removing that.

For some inputs, the error code on EC key creation changes from
PSA_ERROR_INVALID_ARGUMENT to PSA_ERROR_NOT_SUPPORTED or vice versa.
There will be further such changes in subsequent commits.

7bfcfac164 Change key type encodings to avoid bit 16
Key types are now encoded through a category in the upper 4 bits (bits
28-31) and a type-within-category in the next 11 bits (bits 17-27),
with bit 16 unused and bits 0-15 only used for the EC curve or DH
group.

For symmetric keys, bits 20-22 encode the block size (0x0=stream,
0x3=8B, 0x4=16B).

890b5ca330 Change non-blocking read/write in TCP mock socket
Previously mocked non-blocking read/write was returning 0 when buffer was empty/full. That was causing ERR_SSL_CONN_EOF error in tests which was using these mocked callbacks. Beside that non-blocking read/write was returning ERR_SSL_WANT_READ/_WRITE depending on block pattern set by test design. Such behavior forced to redesign of these functions so that they could be used in other tests

95c893d17f More systematic handling of trailing garbage in parse_prefixes
Before, the string to parse may contain trailing garbage (there was
never more than one byte), and there was a separate argument
indicating the length of the content. Now, the string to parse is the
exact content, and the test code runs an extra test step with a
trailing byte added.
