Fix warnings with gcc 5.0

reconnect.c:
- Convert the K&R prototype of main to an ANSI prototype to mute a
  warning from gcc 4.2.1
- Close s_sock2 after finishing off the last test to plug a leak and
  mute a warning from gcc 5.0 about a -Wunused-but-set variable

sendfile.c:
- Fix a -Wunused-but-set warning with gcc 5.0 with pagesize in main(..)
