    consolidate qemu_iovec_memset{,_skip}() into single function and use existing iov_memset() · 3d9b4925

    This patch combines two functions into one, and replaces
    the implementation with already existing iov_memset() from
    iov.c.
    
    The new prototype of qemu_iovec_memset():
      size_t qemu_iovec_memset(qiov, size_t offset, int fillc, size_t bytes)
    It is different from former qemu_iovec_memset_skip(), and
    I want to make other functions to be consistent with it
    too: first how much to skip, second what, and 3rd how many
    of it.  It also returns actual number of bytes filled in,
    which may be less than the requested `bytes' if qiov is
    smaller than offset+bytes, in the same way iov_memset()
    does.
    
    While at it, use utility function iov_memset() from
    iov.h in posix-aio-compat.c, where qiov was used.
