Renamed hmac_ctx to opad and removed null check.
...
this array is now part of the struct and not dynamically allocated
so it can't be null.

psa_hmac_start: reduce stack usage
...
Store the temporary key in the long-key case (where the key is first
hashed) directly into ipad. This reduces the stack usage a little, at
a slight cost in complexity.

HMAC: clean up local variables containing key material
...
In psa_mac_start, the hash of the key and ipad contain material that
can be used to make HMAC calculations with the key, therefore they
must be wiped.
In psa_mac_finish_internal, tmp contains an intermediate value which
could reveal the HMAC. This is definitely sensitive in the verify case,
and marginally sensitive in the finish case (it isn't if the hash
function is ideal, but it could make things worse if the hash function
is partially broken).

Split out CMAC and HMAC code into auxiliary functions
...
Split algorithm-specific code out of psa_mac_start. This makes the
function easier to read.
The behavior is mostly unchanged. In a few cases, errors before
setting a key trigger a context wipe where they didn't. This is a
marginal performance loss but only cases that are an error in caller
code.
