Use 'xmlto man' to make manpages for utils
(docbook2x-man could also be used, but since we already use xmlto...)
This will generate multiple .1 files as an output, but we don't know what they
will be called, so use a timestamp file for build avoidance when the
dependencies haven't changed.

Convert utils.xml from using a sect2 element to using a refentry element for
each utility program. This makes it possible to generate manpage-style output
for those elements.
Note that the chunked html now generates a page for each utility, rather than
one containing all utilities.
A small customization to TOC generation for HTML and PDF is needed to ensure
that it appears as before, containing an entry for each utility command.
Future work: synopsis and options sections could use more detailed markup than
just wrapping the whole thing in <screen>

It seems that xidepend doesn't work correctly if we are ./configure'd using a
relative pathname to the srcdir:

grep: ../../../../src/winsup/doc/cygwin-ug-net.xml: No such file or directory
grep: ../../../../src/winsup/doc/cygwin-api.xml: No such file or directory
Although it might be better to fix this by making xidepend use pathnames, rather
than ignoring them and assuming everything is in the current directory...

windows program. The data before OPOST-processing is written to
output_handle and OPOST-processing is applied in the master-side. For a
cygwin process, OPOST-processing is applied in the slave-side, and the
data after OPOST-processing is written to output_handle_cyg.

and forwards data from io_handle to to_master_cyg. Add function
get_io_handle_cyg() regarding variable io_handle_cyg. Now, the pipe
between io_handle and to_master are used only by native windows program
for applying OPOST-processing in the master-side. For a cygwin process,
the pipe between io_handle_cyg and to_master_cyg is used for passing
through the data which is applied OPOST-processing in the slave-side.
