[PATCH 1/5] winsup/doc: Create info pages from cygwin documentation

[Jon TURNEY <jon.turney@dronecode.org.uk>]

v2:
Updated to use docbook2x-texi not docbook2texi, since source is now docbook XML.
Tweak DocBook XML so info directory entry has a description.

v3:
Use a custom charmap to handle ®

v4:
Proper build avoidance
texinfo node references may not contain ':', so provide alternate text for a few
xref targets

2015-06-22  Jon Turney  <jon.turney@dronecode.org.uk>

	* Makefile.in (install-info, cygwin-ug-net.info)
	(cygwin-api.info): Add.
	* cygwin-ug-net.xml: Add texinfo-node.
	* cygwin-api.xml: Ditto.
	* ntsec.xml (db_home): Add texinfo-node for titles containing a
	':' which are the targets of an xref.
