2ac4d86040 Fix file leak in test program 
A similar bug was fixed earlier in ssl_server2, but we missed the fix
in ssl_client2.

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.

28cd41676e Fix possible error code mangling in psa_mac_verify_finish 
If psa_mac_finish_internal fails (which can only happen due to bad
parameters or hardware problem), the error code was converted to
PSA_ERROR_INVALID_SIGNATURE if the uninitialized stack variable
actual_mac happened to contain the expected MAC. This is a minor bug
but it may be possible to leverage it as part of a longer attack path
in some scenarios.

Reported externally. Found by static analysis.

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.

73c616bdc1 Put includes in alphabetical order 
The library style is to start with the includes corresponding to the
current module and then the rest in alphabetical order. Some modules
have several header files (eg. ssl_internal.h).

The recently added error.h includes did not respect this convention and
this commit restores it. In some cases this is not possible just by
moving the error.h declarations. This commit fixes the pre-existing
order in these instances too.

df587ee6d6 Remove duplicate include statement 
Now that the Error module has error codes as well and is processed by
the generate_errors script like any other module, we don't need to
include the header manually.

865b3ebf84 Initialize return values to an error

2d20567122 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.
