ff3d80ff7e simple optimization: don't bother calling "exists" (which calls the syscall
"access").  Instead, just let the open call fail if the file doesn't exist.
This reduces the # syscalls executed.

84bad2f96c Remove a dead conditional: info_ can only be allocated if FD is good. Improve
spacing

0af7093532 The only entry in the stat buf this code cares about is the size. Keep just
the size, not the whole stat buffer.

946af52687 If errno is zero strerror_r does not modify the buffer, leaving it unterminated.
This causes garbage to be printed out after error messages.

9737492204 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.
