[PATCH v4 00/11] 9p: Add support for darwin

[Will Cohen]

This is a followup to 
https://lists.nongnu.org/archive/html/qemu-devel/2022-01/msg05993.html,
adding 9p server support for Darwin.

Since v3, the following changes have been made:

- Move XATTR_SIZE_MAX to P9_XATTR_SIZE MAX in 9p.h, and provide explanatory 
context as preliminary solution
- Add explanatory note surrounding virtio-9p-test with output of pre-patch 
failing test
- Remove superfluous header guards from file-opt-9p
- Add note about virtfs-proxy-helper being disabled on non-linux for this patch 
series
- Note radar filed with Apple for missing mknodat syscall
- Replace direct syscall to pthread_fchdir with pthread_fchdir_np, and add 
check for this function’s presence in meson
- Ensure that d_seekoff is filled using telldir on darwin, and create 
qemu_dirent_off helper to decide which to access.
- Ensure that [amc]tim.tv_sec are all initialized alongside [amc]tim.tv_nsec in 
9p-proxy
- Ensure that all patch email addresses are valid
- Add telldir error handling for dirent on darwin
