x509 and tls libraries.

#
# Purpose
#
# Show symbols in the X.509 and TLS libraries that are defined in another
# libmbedtlsXXX.a library. This is usually done to list Crypto dependencies.
# Show external links in built libraries (X509 or TLS) or modules. This is
# usually done to list Crypto dependencies or to check modules'
# interdependencies.
#
# Usage:
# - build the library with debug symbols and the config you're interested in
# (default, full minus MBEDTLS_USE_PSA_CRYPTO, full, etc.)
# - run this script with the name of your config as the only argument
# - launch this script with 1 or more arguments depending on the analysis' goal:
# - if only 1 argument is used (which is the name of the used config,
# ex: full), then the analysis is done on libmbedx509 and libmbedtls
# libraries by default
# - if multiple arguments are provided, then modules' names (ex: pk,
# pkparse, pkwrite, etc) are expected after the 1st one and the analysis
# will be done on those modules instead of the libraries.
