Cleanups!
Make some code static, add some const to the PAM code, and make the plaintext password code actually function - particulary without the requirement to modify the 'struct passwd' (which it assumed was made up of fstrings) This kills some particularly ugly code in lib/util_pw.c Andrew Bartlett (This used to be commit 302dad4990ba5194f072e435465d9adaa089ae06)
