Manuel Pégourié-Gonnard a771160799 Introduce new config.h flag for TLS
For now the option has no effect.

Adapted existing example config files. The fact that I needed to do this
highlights that this is a slightly incompatible change: existing users need to
update their existing custom configs (if standalone as opposed to based on the
default config) in order to still get the same behaviour.

The alternative would be to have a negative config option (eg NO_TLS or
DTLS_ONLY) but this doesn't fit as nicely with the existing options, so
hopefully the minor incompatibility is acceptable.

I don't think it's worth adding a new component to all.sh:
- builds with both DTLS and TLS are done in the default (and full) config
- TLS-only builds are done with eg config-suite-b.h in test-ref-configs
- a DTLS-only build is done with config-thread.h in test-ref-configs
- builds with none of them (and SSL_TLS_C enabled) are forbidden

This directory contains example configuration files.

The examples are generally focused on a particular usage case (eg, support for
a restricted number of ciphersuites) and aim at minimizing resource usage for
this target. They can be used as a basis for custom configurations.

These files are complete replacements for the default config.h. To use one of
them, you can pick one of the following methods:

1. Replace the default file include/mbedtls/config.h with the chosen one.
   (Depending on your compiler, you may need to adjust the line with
   #include "mbedtls/check_config.h" then.)

2. Define MBEDTLS_CONFIG_FILE and adjust the include path accordingly.
   For example, using make:

    CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<foo.h>'" make

   Or, using cmake:

    find . -iname '*cmake*' -not -name CMakeLists.txt -exec rm -rf {} +
    CFLAGS="-I$PWD/configs -DMBEDTLS_CONFIG_FILE='<foo.h>'" cmake .
    make

Note that the second method also works if you want to keep your custom
configuration file outside the mbed TLS tree.
