Description of problem:

The chcat Python script has some serious parsing issues when attempting to update contexts, especially when category ranges are involved.

Case 1:
  # chcat c1 /tmp/file; chcat +c2 /tmp/file; chcat +c3 /tmp/file
  # chcat +c5 /tmp/file
  # ls -Z /tmp/file
  -rw-r--r--  root root user_u:object_r:tmp_t:s0:c1.c3,c5 /tmp/file
(fine so far...)
  # chcat +c4 /tmp/file
  /usr/bin/chcat: invalid literal for int(): 3,c5

Case 2:
  # chcon -l s0:c1,c3,c5,c7,c9 /tmp/file
  # ls -Z /tmp/file
  -rw-r--r--  root root user_u:object_r:tmp_t:s0:c1,c3,c5,c7,c9 /tmp/file
  # chcat +c4 /tmp/file
  # ls -Z /tmp/file
  -rw-r--r--  root root user_u:object_r:tmp_t:s0:c1,c3.c5,c7,c9 /tmp/file
(fine so far...)
  # chcat +c6 /tmp/file
  /usr/bin/chcat: invalid literal for int(): 1,c3
