Implement SplitFS using system-call interception rather than library calls

[vijay03]

Use the system-call intercept library: https://github.com/pmem/syscall_intercept in SplitFS instead of intercepting glibc calls. This will make SplitFS more portable and hopefully more robust (different glibc variants will have the same system call implementation).

Is it possible for me to work on this?

@vijay03 @rohankadekodi
I have been working on this.
Current status: POSIX (pjd) test suite integrated and passing successfully in POSIX mode SplitFS.

[vijay03]

Thats great! Can we get a pull request?

[OmSaran]

@vijay03 I have created a draft pull request. #47
Draft because:

1. There are some unwanted files (Quill related) that can be removed (In progress)
2. I wanted to integrate Sync and Strict mode also in this PR itself.

Looking to get above 2 done by 25th Jan.

I was thinking of converting to full pull request once above 2 are complete. Would that be ok?

[vijay03]

That would be great! Let us know when @rohankadekodi and I can review it.

[rohankadekodi]

Thanks a lot Om! This is great news. Yes, please let us know once the other two modes are passing on the PJD test suite and we can review it.
