ref-manual: Updates to clarify Fetcher URL directory parameters 

Updated the SRC_URI variable description to cross-reference
the "Fetchers" section in the BitBake User Manual and added
some more Fetcher URL parameters specific to certain fetchers.
This was done to help clarify how to put fetched code into
specific directories.

Also updated the bin_packages.bbclass description to have a
better example.  Used a git:// fetcher example and provided

some specific URL parameters.

<note>
For RPMs and other packages that do not contain a subdirectory,
you should specify a "subdir" parameter.
you should specify an appropriate fetcher parameter to point to
the subdirectory.
For example, if BitBake is using the Git fetcher
(<filename>git://</filename>), the "subpath" parameter limits
the checkout to a specific subpath of the tree.
Here is an example where <filename>${BP}</filename> is used so that
the files are extracted into the subdirectory expected by the
default value of
<link linkend='var-S'><filename>S</filename></link>:
<literallayout class='monospaced'>
SRC_URI = "http://example.com/downloads/somepackage.rpm;subdir=${BP}"
SRC_URI = "git://example.com/downloads/somepackage.rpm;subpath=${BP}"
</literallayout>

section in the BitBake User Manual for more information on

URI protocols are highly dependent on particular BitBake

Depending on the fetcher BitBake uses, various URL
