a84803e951 Refactor Occlum PAL as a shared library 
By providing Occlum PAL as a shared library, it is now possible to embed and
use Occlum in an user-controled process (instead of an Occlum-controlled one).

The APIs of Occlum PAL can be found in `src/pal/include/occlum_pal_api.h`. The
Occlum PAL library, namely `libocclum-pal.so`, can be found in `.occlum/build/lib`.
To use the library, check out the source code of `occlum-run` (under
`src/run`), which can be seen as a sample code for using the Occlum PAL
library.

1a365de08f Introduce the new error handling mechanism 
* Fast error diagnosing (e.g., backtrace and code location)
* First-class POSIX errno (e.g., every error has an errno)
* Zero-overhead abstraction (e.g., no heap allocation for simple errors)
* Ergonomic grammar (e.g., providing convenient macros)
