b0b189f31f Add missing compilation guards for GCM and CCM 
Add missing compilation guards that broke the build if either GCM or
CCM was not defined.

Add missing guards on test cases that require GCM or CBC.

The build and tests now pass for any subset of {MBEDTLS_CCM_C,
MBEDTLS_GCM_C}. There are still unused variables warnings if neither
is defined.

a16fa297f7 Refactor mpi_write_hlp to not be recursive 
Refactor `mpi_write_hlp()` to not be recursive, to fix stack overflows.
Iterate over the `mbedtls_mpi` division of the radix requested,
until it is zero. Each iteration, put the residue in the next LSB
of the output buffer. Fixes #2190

8220466297 Streamline mbedtls_xxx_drbg_update_seed_file 
Refactor mbedtls_ctr_drbg_update_seed_file and
mbedtls_hmac_drbg_update_seed_file to make the error logic clearer.

The new code does not use fseek, so it works with non-seekable files.

e0e9c573ad HMAC_DRBG: deprecate mbedtls_hmac_drbg_update because it ignores errors 
Deprecate mbedtls_hmac_drbg_update (which returns void) in favor of a
new function mbedtls_hmac_drbg_update_ret which reports error.

5e76952235 Add a facility to configure entropy sources 
Add a function to configure entropy sources. For testing only.

Use it to test that the library initialization fails properly if there is no
entropy source.

82df32e3fd psa: Unused key_bits is OK 
When MD or CMAC are disabled, let the compiler know that it is OK that
`key_bits` is set but not used by casting `key_bits` to `(void)`.

3016de3eeb pk_wrap: rework signature extraction to work with small r and s values 
There is a probability that r will be encoded as 31 or less bytes in DER,
so additional padding is added in such case.
Added a signature-part extraction function to tidy up the code further.
