Per Paul Eggleton's suggestion, I added a new section on
anonymous Python functions into the "Functions" section.
I also updated the intro text to account for the added
type of functions.

bitbake-user-manual-ref-variables.xml: Fixed BBPATH example

The example used in the note in the BBPATH variable description
had incorrect syntax.  Spaces existed in the BBPATH = statement.
I have removed them.

bitbake-user-manual-metadata.xml: Added section on pathname syntax

Added a brief subsection to the "Basic Syntax" section that
describes the issue using the tilde character (~) when providing
a pathname as part of a statement.  BitBake does not expand
this character like the shell does.  We recommend to not use
it in pathnames.
