dfe8bf86a8 Return CORRUPTION_DETECTED instead of BAD_SLOT when the slot's state is wrong
These error codes are only returned if the program has been tampered with,
so they should be CORRUPTION_DETECTED.

4755e6bda4 Relax psa_wipe_key_slot to allow states other than SLOT_PENDING_DELETION
psa_wipe_key_slot can now be called on a slot in any state, if the slot's state
is PSA_SLOT_FULL or PSA_SLOT_PENDING_DELETION then there must be exactly 1 registered
reader.

Remove the state changing calls that are no longer necessary.

62aa79ac5c Implement psa_key_slot_has_readers and remove psa_is_key_slot_occupied
Remove psa_is_key_slot_occupied, any function which calls this can just check
the state variable instead.
Replace psa_is_key_slot_locked with psa_key_slot_has_readers.
References to the now removed functions are changed in future commits.

e820c0abc8 Update spelling "mbed TLS" to "Mbed TLS"
The official spelling of the trade mark changed from all-lowercase "mbed"
to normal proper noun capitalization "Mbed" a few years ago. We've been
using the new spelling in new text but still have the old spelling in a
lot of text. This commit updates most occurrences of "mbed TLS":

```
sed -i -e 's/mbed TLS/Mbed TLS/g' $(git ls-files ':!ChangeLog' ':!tests/data_files/**' ':!tests/suites/*.data' ':!programs/x509/*' ':!configs/tfm*')
```

Justification for the omissions:

* `ChangeLog`: historical text.
* `test/data_files/**`, `tests/suites/*.data`, `programs/x509/*`: many
  occurrences are significant names in certificates and such. Changing
  the spelling would invalidate many signatures and tests.
* `configs/tfm*`: this is an imported file. We'll follow the upstream
  updates.

f8e5b56ad8 Fix get_num_ops internal code.
Previously calling get_num_ops more than once would have ended up with ops
getting double counted, and not calling inbetween completes would have ended up
with ops getting missed. Fix this by moving this to where the work is actually
done, and add tests for double calls to get_num_ops().

f9c91a7fb5 Store the hash, rather than the pointer
For sign and verify, the pointer passed in to the hash is not guaranteed to
remain valid inbetween calls, thus we need to store the hash in the
operation. Added a test to ensure this is the case.

ed73355d2e Make \retval commands non-empty
Pacify Clang >=15 which complained:
```
include/psa/crypto.h:91:23: error: empty paragraph passed to '\retval' command [-Werror,-Wdocumentation]
 * \retval #PSA_SUCCESS
   ~~~~~~~~~~~~~~~~~~~^
```

This commit performs the following systematic replacement:
```
perl -i -0777 -p -e 's/([\\@])(retval +\S+)\n(?! *\*? *([^\n \\*\/]|\\[cp]\b))/$1$2 ${1}emptydescription\n/g' $(git ls-files '*.[hc]' '*.function' '*.jinja')
```
i.e. add an `\emptydescription` argument to `\retval` commands (or
`@retval`, which we don't normally used) that are followed by a single word,
unless the next line looks like it contains text which would be the
description.

Add test driver support for opaque key import
-Add test driver support to import/export while wrapping keys
 meant to be stored in the PSA core as opaque( emulating an
 SE without storage ).
-Export validate_unstructured_key_bit_size as
 psa_validate_unstructured_key_bit_size, thereby changing its scope.
-Improve the import/export test cases in test_suite_psa_crypto to also
 cover opaque keys, thereby avoiding duplication.
