292672eb12 If ASSERT_ALLOC_WEAK fails, mark the test as skipped, not passed 
This was the intended behavior of ASSERT_ALLOC_WEAK all along, but
skipping was not implemented yet when ASSERT_ALLOC_WEAK was
introduced.

42a1acfd0e get_len_step: Fix end-of-buffer calculation when buffer_size==0 
Fix get_len_step when buffer_size==0. The intent of this test is to
ensure (via static or runtime buffer overflow analysis) that
mbedtls_asn1_get_len does not attempt to access beyond the end of the
buffer. When buffer_size is 0 (reached from get_len when parsing a
1-byte buffer), the buffer is buf[1..1] because allocating a 0-byte
buffer might yield a null pointer rather than a valid pointer. In this
case the end of the buffer is p==buf+1, not buf+buffer_size which is
buf+0.

The test passed because calling mbedtls_asn1_get_len(&p,end,...) with
end < p happens to work, but this is not guaranteed.

a15c71374b ctr_drbg: Clarify reseed_counter values before seeding 
Before the initial seeding, reseed_counter used to always be 0. Now, the
value depends on whether or not the user has explicitly set the amount
of data to get from the nonce (via e.g.
mbedtls_ctr_drbg_set_nonce_len()). Add comments to clarify the possible
values reseed_counter can have before the initial seeding.

49af2d3a4f Support non-ASCII characters in headers 
Filter out non-ASCII characters in automatically processed headers.

Do this in a way that minimizes the code change: keep manipulating
strings, but strip off non-ASCII characters when reading lines, which
should only remove characters in comments that we don't parse anyway.

60f6b64b8f Add two error codes to the Error module 
One of the error codes was already reserved, this commit just makes it
explicit. The other one is a new error code for initializing return
values in the library: `MBEDTLS_ERR_ERROR_CORRUPTION_DETECTED` should
not be returned by the library. If it is returned, then it is surely a
bug in the library or somebody is tampering with the device.

afaee1cacf Catch AES failure in mbedtls_ctr_drbg_random 
The functions mbedtls_ctr_drbg_random() and
mbedtls_ctr_drbg_random_with_add() could return 0 if an AES function
failed. This could only happen with alternative AES
implementations (the built-in implementation of the AES functions
involved never fail), typically due to a failure in a hardware
accelerator.

Bug reported and fix proposed by Johan Uppman Bruce and Christoffer
Lauri, Sectra.
