1cc695efd7 Fix redirection of stderr in sys::Program::ExecuteAndWait. There was logic
error that caused it to redirect stderr to stdout too often.

This fix is applied identically to the win32 code as well, but that is
untested.

616e484be4 Make I/O redirection handling in sys::Program a bit more consistent. No
functional changes. Win32 code is untested, but should work fine.

In the unix variant, rename RedirectFD to RedirectIO and let that function
handle empty and null paths instead of doing that in the caller 3 times. This
is the same as win32 already does it.

In the win32 variant, use Path::isEmpty() instead of checking the resulting
c_str() manually. This is the same as unix already does it.

1d0436cdb0 Re-implemented Path::createDirectoryOnDisk (for Unix).
This method allows one to create a directory, and optionally create all parent
directories that do not exist.

The original implementation would require that *all* directories along a path
are writable by the user, including directories that already exist. For example,
suppose we wanted to create the directory "/tmp/foo/bar", and the directory
"/tmp" already exists, but not "/tmp/foo". Since "/tmp" is writable by all
users, the original implementation would work, and create "/tmp/foo", followed
by "/tmp/bar".

A problem occurred, however if one wanted to created the directory
"/Users/myuser/bar" (or equivalently "/home/myuser/bar"), and "/Users/myuser"
already existed and is writable by the current user. The directory
"/User/myuser" is writable by the user, but "/User" is not. The original
implementation of createDirectoryOnDisk would return with failure since "/User"
is not writable, even though "/User/mysuser" is writable.

The new implementation works by recursively creating parents as needed, and thus
doesn't need to check the permissions on every directory in a path.

efecfbc113 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tons of out of date comments (really nothing throws here!)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.
