7fa8cbbd46 a PAM_MODUTIL_DEV_PRIVS structure can't be reused 
so we have to allocate a second one and point to
that for the second time we want to drop privs.
relates to #28

2aaf0fdc23 Stop leaks of memory and of privileges 
Fix several memory leaks and mishandling of the privilege status
where a function returned failure indication, and previously
allocated memory was not freed (and the referece was lost), or
previously droped privileges where not restored.

this bumps the version on the state file to 2
old files can still be read but new files will use the new format

eb78d4882b refactor to use chalresp function from ykpers 
so challenge_response() now calls yk_challenge_response() to
do the yubikey internal stuff.

7dc5c6a155 print information only if debug is specified 
The pam module is very informative. I do not want it to print any
information unless debug is specified. An attacker should not get any
information.

d2c14efdd4 Add missing headers 
fcntl.h in pam_yubico.c is needed on OS X with clang for the build to
succeed, while unistd.h in util.c is required so clang doesn't complain
about implicit declarations of ftruncate and fsync.

a9892dbb44 Drop privileges before opening user files. 
This change also ensures that user tokens are regular files.  We may
want to add a similar check for user challenge files.

4712da70ca Fix big security hole: Authentication succeeded when no password 
was given, unless use_first_pass was being used.
This is fatal if pam_yubico is considered 'sufficient' in the PAM
configuration.
