2b556f8de9 Refactor the CPU scheduling subsystem 
This commits improves both readability and correctness of the scheduling-related
system calls. In terms of readability, it extracts all scheduling-related code
ouf of the process/ directory and put it in a sched/ directory. In terms
of correctness, the new scheduling subsystem introduces CpuSet and SchedAgent
types to maintain and manipulate CPU scheduler settings in a secure and robust way.

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.

* 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)
