In preparation of changing the type of some parameters of
test_chacha20() from `char *` to `data_t` to get rid of the
calls to mbedtls_test_unhexify():
- Reduce the size of output[] buffer to 375 as its content
is "ASCII expended" into a buffer of 751 bytes.
- Align naming of variables to store and check the
output of mbedtls_chacha20_crypt(). No *dst* variables
anynore, only *output* variables.
- Use two different buffers to store the expected output
of mbedtls_chacha20_crypt() (expected_output_str[]) and
the ASCII string representation of the output of
mbedtls_chacha20_crypt() (output_string[]). Both were
stored in dst_str[] before.

In preparation of changing the type of some parameters
of test_hkdf() from `char *` to `data_t` to get rid of the
calls to mbedtls_test_unhexify():
- Align naming of variables related to the expected okm
- Rename `okm_hex[]` to `okm_string[]`
- Added TEST_ASSERT( expected_okm_len <= sizeof( okm ) ) to check
that the okm[] buffer is large enough for the okm output.

In preparation of changing the type of some parameters
of some test functions from `char *` to `data_t` to get
rid of the calls to mbedtls_test_unhexify():
- Align the name of source data length local variable
with the name of the local variable containing the
source data, respectively src_str and src_str_len.
- Change the type of length, index local variables
from int to size_t.

in non-pedantic mode. Define the appropriate POSIX symbol.

When parsing a certificate with the basic constraints extension
the max_pathlen that was read from it was incremented regardless
of its value. However, if the max_pathlen is equal to INT_MAX (which
is highly unlikely), an undefined behaviour would occur.
This commit adds a check to ensure that such value is not accepted
as valid. Relevant tests for INT_MAX and INT_MAX-1 are also introduced.
Certificates added in this commit were generated using the
test_suite_x509write, function test_x509_crt_check. Input data taken
from the "Certificate write check Server1 SHA1" test case, so the generated
files are like the "server1.crt", but with the "is_ca" field set to 1 and
max_pathlen as described by the file name.

The identifiers of the unmet dependencies of a test case are
stored in a buffer of fixed size that can be potentially too
small to store all the unmet dependencies. Indicate in test
reports if some unmet dependencies are missing.

Fix potential buffer overflow when tracking the unmet dependencies
of a test case. The identifiers of unmet dependencies are stored
in an array of fixed size. Ensure that we don't overrun the array.

Use size_t for some variables that are array indices.
Use unsigned for some variables that are counts of "small" things.

Since unmet_dependencies only ever contains strings that are integers
written out in decimal, store the integer instead. Do this
unconditionally since it doesn't cost any extra memory.
This commit saves a little memory and more importantly avoids a gotcha
with uninitialized pointers which caused a bug on development (the
array was only initialized in verbose mode).

(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

CTR_DRBG: Don't use functions before they're defined
HMAC_DRBG: support set_entropy_len() before seed()
None of the test cases in tests_suite_memory_buffer_alloc actually
need MBEDTLS_MEMORY_DEBUG. Some have additional checks when
MBEDTLS_MEMORY_DEBUG but all are useful even without it. So enable
them all and #ifdef out the parts that require DEBUG.
The test case "Memory buffer small buffer" emits a message
"FATAL: verification of first header failed". In this test case, it's
actually expected, but it looks weird to see this message from a
passing test. Add a comment that states this explicitly, and modify
the test description to indicate that the failure is expected, and
change the test function name to be more accurate.
Fix#309
The corner case tests were designed for 32 and 64 bit limbs
independently and performed only on the target platform. On the other
platform they are not corner cases anymore, but we can still exercise
them.
The corner case tests were designed for 64 bit limbs and failed on 32
bit platforms because the numbers in the test ended up being stored in a
different number of limbs and the function (correctly) returnd an error
upon receiving them.
The signature of mbedtls_mpi_cmp_mpi_ct() meant to support using it in
place of mbedtls_mpi_cmp_mpi(). This meant full comparison functionality
and a signed result.
To make the function more universal and friendly to constant time
coding, we change the result type to unsigned. Theoretically, we could
encode the comparison result in an unsigned value, but it would be less
intuitive.
Therefore we won't be able to represent the result as unsigned anymore
and the functionality will be constrained to checking if the first
operand is less than the second. This is sufficient to support the
current use case and to check any relationship between MPIs.
The only drawback is that we need to call the function twice when
checking for equality, but this can be optimised later if an when it is
needed.
mbedtls_ctr_drbg_seed() always set the entropy length to the default,
so a call to mbedtls_ctr_drbg_set_entropy_len() before seed() had no
effect. Change this to the more intuitive behavior that
set_entropy_len() sets the entropy length and seed() respects that and
only uses the default entropy length if there was no call to
set_entropy_len().
The former test-only function mbedtls_ctr_drbg_seed_entropy_len() is
no longer used, but keep it for strict ABI compatibility.
