7d4b0d778f Reuse PSA_MAC_LENGTH in psa_get_mac_output_length 
Avoid code duplication. Also update the guarantees made by the function
doc to match the guarantees given by PSA_MAC_LENGTH.

1ac5ce3b91 Make psa_key_policy_algorithm_intersection MAC-length aware 
This makes it more in-line with how psa_key_policy_permits works. It
also adds consistency: the intersection of MAC with default length and
MAC with exact-length is now computed correctly in case the exact length
equals the default length of the algorithm when used with the given
key type.

Fix sloppy wording around stricly less-than vs less or equal in

calling setrlimit if the limit was exactly the minimum required for

ddf4374879 Fix stack buffer overflow in net functions with large file descriptor 
Fix a stack buffer overflow with mbedtls_net_poll() and
mbedtls_net_recv_timeout() when given a file descriptor that is beyond
FD_SETSIZE. The bug was due to not checking that the file descriptor
is within the range of an fd_set object.

Fix #4169

6667a78c9b Add test for mbedtls_net_poll beyond FD_SETSIZE 
mbedtls_net_poll() and mbedtls_net_recv_timeout() rely on select(),
which represents sets of file descriptors through the fd_set type.
This type cannot hold file descriptors larger than FD_SETSIZE. Make
sure that these functions identify this failure code.

Without a proper range check of the file descriptor in the
mbedtls_net_xxx function, this test fails when running with UBSan:
```
net_poll beyond FD_SETSIZE ........................................ source/library/net_sockets.c:482:9: runtime error: index 16 out of bounds for type '__fd_mask [16]'
SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior source/library/net_sockets.c:482:9 in
```
This is a non-regression test for
https://github.com/ARMmbed/mbedtls/issues/4169 .

The implementation of this test is specific to Unix-like platforms.
