o Minor bugfixes (portability):
|
||||
- Add Tor compatibility function for fgets(3) due to inconsistency of
|
||||
returned values in different supported C libraries. This fixes unit test
|
||||
failures reported on FreeBSD. Fixes bug 20988.

o Code simplifications and refactoring
|

- Use unbuffered I/O for utility functions around the process_handle_t
