bitbake: user-manual: Import YP Docs templates for usermanual improvements

Import the necessary pieces to be able to build the BitBake User
Manual using make in a similar way that the Yocto Documentation is
built.  The Makefile has been edited to remove Yocto Project specific
content and adapt for bitbake's needs.

+# This is a single Makefile to handle all generated BitBake documents.
+# The Makefile needs to live in the documentation directory and all figures used
+# in any manuals must be .PNG files and live in the individual book's figures
+# directory.
+#
+# The Makefile has these targets:
+#
+#    pdf:      generates a PDF version of a manual.
+#    html:     generates an HTML version of a manual.
+#    tarball:  creates a tarball for the doc files.
+#    validate: validates
+#    clean:    removes files
+#
+# The Makefile generates an HTML and PDF version of every document.  The
+# variable DOC indicates the folder name for a given manual.
+#
+# To build a manual, you must invoke 'make' with the DOC argument.
+#
+# Examples:
+#
+#     make DOC=user-manual
+#     make pdf DOC=user-manual
+#
+# The first example generates the HTML and PDF versions of the User Manual.
+# The second example generates the HTML version only of the User Manual. 
+#
