Example loading an enclave from a buffer

1. The library in lib creates an enclave.signed.so and an untrusted.so; and
2. The application in app creates an enclave from the trusted DSO using sgx_create_enclave_from_buffer_ex and loads the untrusted DSO using dlopen

The application then invokes multiple ecalls.

Compilation

First compile library:

.../lib$ make genkey
.../lib$ make SGX_MODE=HW

Then compile application and execute:

.../app$ make SGX_MODE=HW
.../app$ ./app_ex

Clean with:

.../lib$ make clean
.../lib$ make delkey
.../app$ make clean

NOTE: The private key life cycle is independent of the rest of the code. Generate the private key with $ make genkey and remove it with $ make delkey. These targets uses OpenSSL.
