Add DSO size to perf report/top sort output list.
This includes adding a map__size fn to map.h, which is
approximately equal to the DSO data file_size:
DSO file size map (end-start) file / (end-start)

Sample output:
$ ./perf report -s dso_size,dso

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
