Remove MappedFile support for mapping files for write and exec
...
and shared. This complicates the design, is not used, and probably
doesn't even work.

cleanup the MappedFile API and comments. This removes and updates
...
tons of out of date comments (really nothing throws here!) and fixes
some other fairly glaring issues: "size" used to return the size of
the file *and* change it, depending on how you called it.

First version of the MappedFile abstraction for operating system idependent

mapping of files. This first version uses mmap where its available. The
class needs to implement an alternate mechanism based on malloc'd memory
and file reading/writing for platforms without virtual memory.
