The client previously reproted the offered ciphersuites through
their numerical identifier only, while the server reported them
through their name.
This commit modifies the debug output on client and server to
both use the format `ID (NAME)` for the ciphersuites.
The example application programs/ssl/ssl_client2 allows the
configuration of a client CRT through the parameters
- crt_file, key_file
However, password protected key files are not supported.
This commit adds a new command line option
- key_pwd
which allow to specify a password for the key file specified
in the key_file parameter.
The example application programs/ssl/ssl_server2 allows the
configuration of up to two CRTs through the command line
parameters
- crt_file, key_file
- crt_file2, key_file2.
However, password protected key files are not supported.
This commit adds command line options
- key_pwd
- key_pwd2
which allow to specify passwords for the key files specified
in key_file and key_file2, respectively.

There is little point in leaving the order in which drivers are
considered unspecified. This gives flexibility to the implementation
for a process that is generally performed at build time, not in a
constrained environment. Having a well-defined order is especially
useful with fallback.

It's ok if they map to the same function names and an error otherwise.
It's an error to have multiple opaque drivers for the same location.
If multiple transparent drivers apply, which one applies is unspecified.

The existing description of the syntax of capabilities also describes
the semantics of each property, but the semantics of the capability as
a whole is not immediately clear. Add a subsection that explains
precisely when a capability is applicable.

Inferring entry points from algorithms is nice in that it makes
capability specifications shorter and less redundant, but that's not
really important. It also makes capabilities more fragile: if the core
starts supporting new mechanisms based on the same algorithm (for
example, adding hash-and-sign when only sign-the-hash existed before),
a driver only supporting the old mechanisms would fail at build time.
So make entry points mandatory.
This has the benefit of making the semantics of capabilities easier to
describe.

Add the mention of key_derivation_output_key in the section about the
key derivation entry point family.
Rename "derive_key" to "key_derivation_output_key". At this point,
there's no reason to deviate from the naming convention.

Locations aren't in the official PSA API specification yet (they've
only be made public in Mbed TLS). Until version 1.0.1 of the API
specification is out, this document needs to explain locations.

Since it is being dereferenced by free on exit it should be inited to NULL.
Also added a small test that would trigger the issue.

* Set output buffer to zero if key output fails
* Document internal functions and rearrange order of input arguments to
better match other functions.

Rather than have some functions take the in-memory copy of the
persistent data as argument, allow all of them to access the
persistent data, including modifying it.

Opaque drivers only have a destroy function if the key is stored in
the secure element.
Expand on how key creation works. Provide more explanations of
allocate_key in drivers for secure elements with storage. Discuss key
destruction as well.
