[RFC PATCH] perfbook/papersize: ebook reader size support

[Balbir Singh <bsingharora@gmail.com>]

Add support for ebooksize, which is roughly the size of
a kindle (4.5in, 6.3in) with margin size of 0.2in. The
recommended changes were taken from stackexchange with
links in the code. Not all tables take nicely to the
new nice and warnings are produced, which causes warnings
about overfull hbox's to be generated. This mode enforces
single column output and increases the size of the pdf
by almost 40% in terms of number of pages. The final output
though is very readable on the kindle I own.

I've been running the command via

env PERFBOOK_PAPER=ER make perfbook-1c.pdf

and love the output so far.
