c14ee62678 Add untrusted environment variable override 
Add "untrusted" sections for environment variables defined in Occlum.json. Environment
variable defined in "default" will be shown in libos directly. Environment variable
defined in "untrusted" can be passed from occlum run or PAL layer and can override
the value in "default" and thus is considered "untrusted".

6d72e10fc1 Add Golang toolchain and the demo 
This commit provides a modified Go runtime in Docker image.
Now we can build a Go program using `occlum-go`, then run it
in SGX enclaves by Occlum.
The Golang demo demonstrates how to build and run a web server
program written in Go.

6e140a0d38 Add errno info for ECalls 
Before this commit, the three ECalls of the LibOS enclave do not give
the exact reason on error. In this commit, we modify the enclave entry code
to return the errno and list all possible values of errno in Enclave.edl.

e166382923 Add the signal subsystem 
In this commit, we add eight signal-related syscalls
* kill
* tkill
* tgkill
* rt_sigaction
* rt_sigreturn
* rt_sigprocmask
* rt_sigpending
* exit_group

We implement the following major features for signals:
* Generate, mask, and deliver signals
* Support user-defined signal handlers
    * Support nested invocation of signal handlers
    * Support passing arguments: signum, sigaction, and ucontext
* Support both process-directed and thread-directed signals
* Capture hardware exceptions and convert them to signals
* Deliver fatal signals (like SIGKILL) to kill processes gracefully

But we still have gaps, including but not limited to the points below:
* Convert #PF (page fault) and #GP (general protection) exceptions to signals
* Force delivery of signals via interrupt
* Support simulation mode

48d7f8df3e Fix the invalid epoll_event pointer introduced by compilation optimization 
That pointer does not point to the libc::epoll_event after release
build. Explicitly declaring the libc::epoll_event avoids the
invalidation.
