off_t is a type which is used for file offsets. Even more specifically, it is only used by a limited number of C APIs that deal with files. Any usage of off_t where the variable is not intended to be used with one of these APIs is a bug, by definition. This patch corrects some easy mis-uses of off_t, generally by converting them to lldb::offset_t, but sometimes by using other types such as size_t, when appropriate. The use of off_t to represent these offsets has worked fine in practice on linux-y platforms, since we used _FILE_OFFSET_64 to guarantee that off_t was a uint64. On Windows, however, _FILE_OFFSET_64 is unrecognized, and off_t will always be 32-bit. So the usage of off_t on Windows actually leads to legitimate bugs.
