Gets a #GFileError constant based on the passed-in err_no.
For example, if you pass in EEXIST this function returns
G_FILE_ERROR_EXIST. Unlike errno values, you can portably
assume that all #GFileError values will exist.
Normally a #GFileError value goes into a #GError returned
from a function that manipulates files. So you would use
glib.global.fileErrorFromErrno when constructing a #GError.
