Removed openssl, and curl, and added mbedded tls.curl-removal
Almost fully removed curl, needs more testing. Fixed most issues, now trying to cross compile. Fix? Sigh.

+ * Zeroize application for debugger-driven testing
+ *
+ * This is a simple test application used for debugger-driven testing to check
+ * whether calls to mbedtls_platform_zeroize() are being eliminated by compiler
+ * optimizations. This application is used by the GDB script at
+ * tests/scripts/test_zeroize.gdb: the script sets a breakpoint at the last
+ * return statement in the main() function of this program. The debugger
+ * facilities are then used to manually inspect the memory and verify that the
+ * call to mbedtls_platform_zeroize() was not eliminated.
