6cb368fbbe [libos] Retain red zone area and FLAGS unmodified across syscall 
1. The previous implementation of __occlum_syret usse the red zone to
save the register temporarily, which may overwrite the red zone area.
This change avoids using the red zone when handling syscall.

2. Save and restore the FLAGS register before and after the operations
on PKRU to keep the FLAGS unmodified.

12cb488f36 [libos] Fix vulnerable nonce in DCAP verifier 
This commit fixed a security issue in the dcap verifier. The issue was caused by the '[in, out]' attributes of pointer parameter qve_report_info in the ocall function occlum_ocall_verify_dcap_quote(). This led to the vulnerability where the protected qve_report_info.nonce field in libos could be arbitrarily rewritten by attacker outside libos.

4c3ca79134 Make vfork stop parent child threads 
When vfork is called and the current process has other running child threads,
for Linux, the other threads remain running. For Occlum, this behavior is
different. All the other threads will be frozen until the vfork returns
or execve is called in the child process.

The reason is that since Occlum doesn't support fork, many applications will
use vfork to replace fork. For multi-threaded applications, if vfork doesn't
stop other child threads, the application will be more likely to fail because
the child process directly uses the VM and the file table of the parent process.
