Jon TURNEY 5ea698c437 winsup/doc: Create info pages from cygwin documentation
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.

Jon TURNEY 2ef3009068 winsup/doc: Fix xidepend to handle relative pathnames
It seems that xidepend doesn't work correctly if we are ./configure'd using a
relative pathname to the srcdir:

cd ../../../../src/winsup/doc && ./xidepend ../../../../src/winsup/doc/cygwin-ug-net.xml ../../../../src/winsup/doc/cygwin-api.xml >"/wip/cygwin/build/x86_64-unknown-cygwin/winsup/doc/Makefile.dep"
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...
