a579f84e90 Enable new system call mechanism via Auxiliary Vector 
The old system call mechanism works by relocating the symbol __occlum_syscall
provided by libocclum_stub.so to the real entry point of the LibOS. This symbol
relocation is done by the program loader. Now, the new system call mechanism is
based on passing the entry point via the auxiliary vector. This new mechanism
is simpler and is more compatible with the upcoming support for ld.so.

Changes:
1. Fix a bug in serializing auxiliary vector in the stack of a user program;
2. Passing syscall entry via auxiliary vector;
3. Remove relocating for the __occlum_syscall symbol;
4. Remove the dependency on libocclum_stub.so in tests.

c096e7d0b9 Inform Intel SGX SDK about Occlum-defined stacks 
There are two types of stacks: the kernel ones and the user ones. The kernel
stacks are used by Occlum and managed by Intel SGX SDK itself, while the user
stacks are used by the threads created and managed by Occlum. These user stacks
are transparent to Intel SGX SDK so far.

The problem is that Intel SGX SDK needs to be aware of the user stacks.
SGX exception handlers will check whether the rsp value---when the exception
happened---is within the stack of the current SGX thread. If the check fails,
the registered exception handler will not be triggered. But when exceptions are
triggered by the threads running upon Occlum, the rsp value points to the user
stacks, which Intel SGX SDK are completely unware of. So the check always
fails.

Therefore, we extend Intel SGX SDK with two new APIs:

  int sgx_enable_user_stack(size_t stack_base, size_t stack_limit);
  void sgx_disable_user_stack(void);

And this commit uses the two APIs to inform Intel SGX SDK about the
Occlum-managed stacks. And the rsp checks in SGX exception handlers will
check whether rsp is within the user stacks.
