virtiofsd: Fix side-effect in assert()
It is bad practice to put an expression with a side-effect in
assert() because the side-effect won't happen if the code is
compiled with -DNDEBUG.
Use an intermediate variable. Consolidate this in an macro to
have proper line numbers when the assertion is hit.
virtiofsd: ../../tools/virtiofsd/passthrough_ll.c:2797: lo_getxattr:
Assertion `fchdir_res == 0' failed.
Aborted
2796 /* fchdir should not fail here */
=>2797 FCHDIR_NOFAIL(lo->proc_self_fd);
2798 ret = getxattr(procname, name, value, size);
2799 FCHDIR_NOFAIL(lo->root.fd);

When -o xattrmap is used, it will not work unless xattr is enabled.
This patch enables xattr when -o xattrmap is used.

virtiofsd: Don't assume header layout
virtiofsd incorrectly assumed a fixed set of header layout in the virt
queue; assuming that the fuse and write headers were conveniently
separated from the data; the spec doesn't allow us to take that
convenience, so fix it up to deal with it the hard way.

virtiofsd: Changed allocations of iovec to GLib's functions
Replaced the calls to malloc()/calloc() and their respective
calls to free() of iovec structs with GLib's allocation and
deallocation functions and used g_autofree when appropriate.
Replaced the allocation of in_sg_cpy to g_new() instead of a call
to calloc() and a null-checking assertion. Not g_new0()
because the buffer is immediately overwritten using memcpy.

virtiofsd: Changed allocations of fv_VuDev & its internals to GLib functions
Changed the allocations of fv_VuDev structs, VuDev structs, and
fv_QueueInfo strcuts from using calloc()/realloc() & free() to using
the equivalent functions from GLib.
In instances, removed the pair of allocation and assertion for
non-NULL checking with a GLib function that aborts on error.
Removed NULL-checking for fv_VuDev struct allocation and used
a GLib function that crashes on error; namely, g_new0(). This
is because allocating one struct should not be a problem on an
healthy system. Also following the pattern of aborting-on-null
behaviour that is taken with allocating VuDev structs and
fv_QueueInfo structs.
