d3b2fcb7c6 Don't store client-supported ECs in heap-allocated buffer
So far, the client-proposed list of elliptic curves was stored for the
duration of the entire handshake in a heap-allocated buffer referenced
from mbedtls_ssl_handshake_params::curves. It is used in the following
places:
1) When the server chooses a suitable ciphersuite, it checks that
   it has a certificate matching the ciphersuite; in particular, if
   the ciphersuite involves ECDHE, the server needs an EC certificate
   with a curve suitable for the client.
2) When performing the ECDHE key exchange, the server choose one
   curve among those proposed by the client which matches the server's
   own supported curve configuration.

This commit removes the hold back the entire client-side curve list
during the handshake, by performing (1) and (2) on during ClientHello
parsing, and in case of (2) only remembering the curve chosen for ECDHE
within mbedtls_ssl_handshake_params.

b391766802 Fix unused variable that happened during merge
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.

bc6b59859f [Fixup] Add missing PK release call in Cert Verify parsing
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.

33cb3e1c7e Remove cache callbacks from config on client
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.
