Older versions of gcc don't accept variable declations after a case
statement without starting a code block with '{'.

an index in an array in a debug statement.

In case a hash algorithm id has a value >= 64 print out and error. This
should never occur since any hash algorithm id should have been set through
unmarshalling or by TPM 2-internal code.

Enable Camellia-192 and AES-192 and bump up the stateFormatLevel to '4'.
This now prevents using this state with previous stateFormatLevels (< 4)
because there Camellia-192 or AES-192 was not enabled and the user would
otherwise not be able to decrypt data with either one if it was usable.

Enable new commands ECC_Decrypt and ECC_Encrypt in the TPmProfile.h
and also in the 'default' profile. Since the additional commands extend
the ppList and auditCommands array, bump up the version of the stateLevel
to '2' and use the new marshalling functions by using the PERSISTENT_DATA
blob_version '5'.

Switch the implementation to uncompressed lists (from now on it must
remain uncompressed lists forever) and adapt functions who marshal
and unmarshal arrays that are affected by this switch:
- PERSISTENT_DATA.ppList
- PERSISTENT_DATA.auditCommands

The maximum SEED_COMPAT_LEVEL that libtpms may use depends on the earliest
version of libtpms that a profile can run on. Therefore, implement
RuntimeProfileGetSeedCompatLevel() to determine the SEED_COMPAT_LEVEL that
a profile can use, which depends on the profile's stateCompatLevel (which
in turn depends on the version of libtpms)

Add a new API call TPMLIB_SetProfile that enables a user to set a profile.
The user gets control over the name of the profile to apply and may supply
the algoritms to enable. The user does not get control over the individual
commands to enable.

For profiles that work for libtpms v0.10 or later, so for
StatFormatLevel >=2, use ANY_MARSHAL_Object to write OBJECTS into
the NVRAM. This way OBJECTS are written in a more compact format.

Runtime-disabling any hash algorithm also means that the corresponding
hash bank must be disabled as well. In case the SHA-1 bank is disabled,
the output of TPM2_GetCapability must therefore filter-out the SHA-1 bank
that is still compiled-in but otherwise cannot be used.
