Gilles Peskine 4e1174967a Revert "config: Remove TLS and NET options"
This reverts commit 1c66e48670.

Conflicts:
* include/mbedtls/check_config.h:
    * MBEDTLS_SSL_PROTO_SSL3: there has been an addition (of
      MBEDTLS_SHA512_NO_SHA384) at the place where it was removed. Re-add it
      after (alphabetical order).
    * MBEDTLS_ENABLE_WEAK_CIPHERSUITES: there has been an addition (of
      MBEDTLS_CTR_DRBG_USE_128_BIT_KEY) at the place where it was removed.
      Re-add it after (alphabetical order).
    * MBEDTLS_SSL_ALL_ALERT_MESSAGES: there has been an addition (of
      MBEDTLS_SHA512_SMALLER) at the place where it was removed. Re-add it
      after (alphabetical order).

    * MBEDTLS_ENABLE_WEAK_CIPHERSUITES: there has been an addition (of
      MBEDTLS_CTR_DRBG_USE_128_BIT_KEY) at the place where it was removed.
      Re-add it after (alphabetical order).
    * MBEDTLS_SSL_ALL_ALERT_MESSAGES: there has been an addition (of
      MBEDTLS_SHA512_SMALLER) at the place where it was removed. Re-add it
      after (alphabetical order).
* library/version_features.c: re-generate by running
  scripts/generate_features.pl.
* programs/test/query_config.c: re-generate by running
  scripts/generate_query_config.pl.
* scripts/config.pl: this file has been replaced by config.py. Port
  the reversed changes to config.py:
    * Revert removing three symbols from the list of symbols to
      exclude from full.
    * Revert removing one symbol (MBEDTLS_NET_C) from the list of symbols
      to exclude from baremetal.
* scripts/footprint.sh:
    * Re-add the line to unset MBEDTLS_NET_C, but with config.py instead of
      config.pl.
* tests/scripts/all.sh:
    * component_test_no_platform: re-add the line to unset MBEDTLS_NET_C, but
      with config.py instead of config.pl.
    * component_build_arm_none_eabi_gcc,
    component_build_arm_none_eabi_gcc_no_udbl_division,
    component_build_arm_none_eabi_gcc_no_64bit_multiplication,
    component_build_armcc: these components now use the baremetal
    configuration, so they do not need to turn off MBEDTLS_NET_C explicitly.
