Ticket #2053: readline-read-write-history-1.patch

New patches:

[Added read_history and write_history bindings
alexander.dunlap@gmail.com**20080119065222
 
 These bindings allow programs to have readline save the history for a session and then reload it in a future session. Many programs utilizing the history features of readline will want to allow users to scroll back through future sessions. (The direct motivation for this patch was adding a persistent history capability for GHCi.)

Ross Paterson <ross@soi.city.ac.uk>**20071107005850
 
 This was used when building in the GHC tree using the old fptools build
 system, to pass parameters from configure to the Makefile.  With the new
 Cabal-based build system, they go via readline.buildinfo.

 For now readline simply ignores any failure when asked to build, but we
 really need to do something better here!

[Move readline configuration into the readline package
Simon Marlow <simonmar@microsoft.com>**20060609135511
 
 Configuration of the readline package is now done with a
 package-private configure script, which takes it a step closer to
 being a standalone Cabal package.
 
 At the same time I added --with-readline-includes and
 --with-readline-libraries options to cater for systems where these
 libraries live in non-std places.
