When the PSA crypto features need to be setup based on the
PSA_WANT_xxx macros, the dependent features also need to be
enabled. This change corrects that for the MBEDTLS_ECDSA_DETERMINISTIC.

Updated the test_psa_want_ecdsa_disabled_software to enable and disable
the correct macros to accomplish the desired test. The previous version
left out the disabling of additional macros to ensure items related
to MBEDTLS_ECDSA_C were also unset. The test was also missing the setting
of the accelerators MBEDTLS_PSA_ACCEL_ALG_ECDSA and DETERMINISTIC_ECDSA.
With the accelerators enabled the test portion had to be temporarily
disabled until the accelerator code is completed so the test will work
properly.
Updated the signature driver source to fix a compiler warning when
MBEDTLS_ECDSA_C is unset.

will not support cmake 2.6 any more
* This PR updates the mimimum required cmake version
to 2.8.12, which will not give a warning with cmake 3.19
but still compatible with MbedTLS support of RHEL/CentOS 7 LTS

In `read_next_b64_code()`, the result of fgetc() is stored into a char,
but later compared against EOF, which is generally -1. On platforms
where char is unsigned, this generates a compiler warning/error that the
comparison will never be true (causing a build failure). The value will
never match, with the function ultimately bailing with a "Too many bad
symbols are detected" error.
On platforms with signed char, EOF is detected, but a file containing a
0xFF character will causes a premature end of file exit of the loop.
Fix this by changing the result to an int.
Fixes#3794.

Mbed TLS requires users of DTLS to configure timer callbacks
needed to implement the wait-and-retransmit logic of DTLS.
Previously, the presence of these timer callbacks was checked
at every invocation of `mbedtls_ssl_fetch_input()`, so lowest
layer of the messaging stack interfacing with the underlying
transport.
This commit removes this recurring check and instead checks the
presence of timers once at the beginning of the handshake.
The main rationale for this change is that it is a step towards
separating the various layers of the messaging stack more cleanly:
datagram layer, record layer, message layer, retransmission layer.

The psa crypto library was generically using PSA_WANT_ALG_xxx, but
should have been using the correct MBEDTLS_PSA_BUILTIN_ALG_xxx
definition since that code is the builtin version. There were also
a couple of spots that needed to ensure the code block was enabled
for either ECDSA or DETERMINISTIC_ECDSA, not just one of them.
Fixed all the new ALG_ECDSA_DETERMINISTIC names to be
ALG_DETERMINISTIC_ECDSA instead.
Fixed test to use correct definitions.

Provied a more detailed description for the config_psa.h header file.
This new description makes it clear that the file should not be edited

psa/crypto_config.h instead.
Fixed the logic for the inclusion of MBEDTLS_PSA_BUILTIN_XXX to be set
when PSA_WANT_ALG_XXX and MBEDTLS_PSA_ACCEL_ALG_XXX is not defined,
otherwise the MBEDTLS_XXX should be set.

The CCM specification (NIST SP 800-38C) mandates that the formatting of
the additional data length l(a) changes when it is greater _or equal_ to
2^16 - 2^8 (>= 0xFF00). Since such lengths are not supported in mbed TLS,
the operation should fail in such cases.
This commit fixes an off-by-one error which allowed encryption/decryption
to be executed when l(a) was equal to 0xFF00, resulting in an
incorrect/non-standard length format being used.
Fixes#3719.
