This patch changes the top level handlers to coroutines and sets the base.
It will be followed up with series of patches to convert all filesystem
calls to threaded coroutines pushing all blocking clals in VirtFS out
of vcpu threads.

Current rpath inline function is heavily used in all system calls.
This function has a static buffer making it a non-thread safe function.
This patch introduces new thread-safe routine and makes use of it.

Commit 353ac78d moved the files
without fixing the include paths. It used a modified CFLAGS
to add hw to the include search path, but this breaks builds
where the user wants to set special CFLAGS. Long include paths
also increase compilation time.

Therefore this patch removes the special CFLAGS for virtio
and fixes the include statements by using relative include paths.

v2: Remove special CFLAGS.
v3: Update needed for latest QEMU.

This patch removes the addition of null char in symlink file
