support macOS High Sierra by removing unnecessary save of VMCS fields
In Linux and POSIX, unlink() is defined to remove the link itself if it is a symoblic link, rather than following the link. Otherwise, we cannot remove cyclic links such as "x -> x".
In Linux and POSIX, if the old path refers to a symbolic link, the link is renamed. Otherwise, we cannot rename links.
In the previous bound check, msync() fails for exactly the same size mm_region.
mmap() should return errno, not panic, if the guest Linux application passed an invalid parameter.
shmat() maps the memory region without executable permission by default, while Noah tries to map the region onto the VM with executable permission, and it fails. It also incorrectly returns the host address instead of the guest address.
sendto() did not use the sockaddr parameter, so implemented it.
socketpair() did not register the returned file descripters internally, causing the subsequent read() to fail.
recvfrom() copied data by the buffer size, but it should copy only the amount actually received.
open() internally uses the "struct file" array. The array is expanded when necessary with realloc(). realloc() may first free the old memory region and then allocate a new region. However, a pointer into the array might be still in use when the array is expanded, causing use-after-free. This patch introduces a two-level page-table-like data structure to avoid reallocating the "struct file" array.
futex() did not implement this, causing pthread_join() to wait forever if FUTEX_WAIT is called after FUTEX_WAKE.
