[PATCH 0/2] virtio-9p: move G_GNUC_PRINTF to header

[Sean Wei <me@sean.taipei>]

v9fs_string_sprintf() and v9fs_path_sprintf() already have
G_GNUC_PRINTF annotations in their own *.c files, but the
prototypes in the corresponding headers lack them.  When another
translation unit includes only the header, -Wformat can no longer
validate the argument list.

This series relocates the annotations to fsdev/9p-marshal.h and
hw/9pfs/9p.h, then drops the now-redundant annotations in
the *.c files.  There is no functional change.

I've checked all call sites for these two helper function, all
of them already passes the correct number of arguments.

A minimal PoC (sent as the next mail in the thread) demo how
G_GNUC_PRINTF behaves differently when the attribute is present
only in code.c or code.h file.
