Fix an "unused variable" warning that happened in some configurations
(without EC, found by depend-pkalg.pl) and was not present in any parent PR
but only in the result of merging them: one of the PRs clarified the
distinction between `ret` and `verify_ret` and the other removed one
occurrence of using `ret`, and the conjunction of the two made `ret` unused in
some cases. Resolving by reducing the scope of that variable.

This commit modifies the baremetal configuration to disables the inclusion
of the list of accepted CAs in the CertificateRequest message sent by the
server.

mbedtls_ssl_read() can fail non-fatally, in which case
ssl_parse_certificate_verify() returned immediately without
calling mbedtls_x509_crt_pk_release(), which in turn lead
to a fatal error because of nested acquire calls in the
next call to the function.
There are a number of PRs in flight that are going to append to the list of
getter functions for harcodeable SSL conf items, so leave that list at the end
in order to avoid conflicts between this PR and the SSL conf ones.
While not strictly related to this PR, this change improves readability in
some resumption-related runtime conditions that previously had rather ugly
preprocessor directives in the middle of already complex predicates.
Due to previous change of conditions, this is now in the 'else' branch of 'if
resume == 1' and the only allowed values are 0 or 1, so setting to 0 is
redundant.
The session cache is only server-side. This also aligns the conditions
guarding those fields with the condition guarding the function setting them -
no need to have the fields if we can't set them.
This preserves the API and ABI in the default config as it only affects
non-default configs.
Add a new configuration option MBEDTLS_SSL_SESSION_RESUMPTION
to enable/disable the session resumption feature including
ticket and cache based session resumption.
Resource counting as a safe-guard against nested acquire calls
is implemented if and only if MBEDTLS_X509_ALWAYS_FLUSH is disabled
_or_ MBEDTLS_THREADING_C is enabled.
Oz is allowed to make size optimizations that make the code slower,
where Os isn't. Optimize with Oz, as we care more about having a small
code footprint than having fast code.
