Instead of declaring our own err() which is different than the standard one,
...
and using it incorrectly in a few places because of confusion (does it print
errno or not?), declare two versions following the standard ones xerrx and,
xerr, and use those as appropriate, implementing them using them vwarn and
vwarnx.

Remove tracking of file size by how many characters were output.
...
This succumbs to a race condition where data are written to the
file while the sleep is occurring. If a stat is done immediately
after, lastsize is updated but the file pointer wasn't pointing at
the end of the file, so the number of bytes between the current
pointer and the end of the file is added to the lastsize when
lastsize already points to the end of the file.
