PROXY: Do not abuse data provider interface We want to use custom interface for proxy provider so we do not abuse the data provider one. This way we gain more control over it and we can remove the old interface entirely. Reviewed-by: Lukáš Slebodník <lslebodn@redhat.com>

PROXY: Do not register signal with SA_SIGINFO Argument "siginfo_t *siginfo" (void *__siginfo) was not used in signal handlers pc_init_sig_handler, proxy_child_sig_handler. siginfo is mostly used for additional information for about signal and precesses (@see man 2 sigaction) and we store needed information in custom context (private_data); It's tevent style. Why backend crashed: proxy_child_init_send creates request; forks a process and register handler for signal SIGCHLD. Talloc parent of tevent_signal is previously created request. If proxy_child fails (return code is not 0) then SIGCHLD is received handler pc_init_sig_handler is called. However pc_init_sig_handler can call tevent_req_error for request which calls request callback and released request. tevent_signal_destructor was called as a part of releasing tevent_signal. The destructor cleared siginfo in ring buffer for first time. Then tevent tried to clear the same siginfo in ring buffer for the secont time after returning from signal hander (pc_init_sig_handler). But it was already cleared and it caused dereference of NULL pointer. Resolves: https://fedorahosted.org/sssd/ticket/2654 Reviewed-by: Michal Židek <mzidek@redhat.com>

Fix formating of variables with type: unsigned long

Check for correct variable name https://fedorahosted.org/sssd/ticket/1864

Making the authtok structure really opaque. Definition of structure sss_auth_token was removed from header file authtok.h and there left only declaration of this structure. Therefore only way how to use this structure is to use accessory function from same header file. To creating new empty authotok can only be used newly created function sss_authtok_new(). TALLOC context was removed from copy and setter functions, because pointer to stuct sss_auth_token is used as a memory context. All declaration of struct sss_auth_token variables was replaced with pointer to this structure and related changes was made in source code. Function copy_pam_data can copy from argument src which was dynamically allocated with function create_pam_data() or zero initialized struct pam_data allocated on stack. https://fedorahosted.org/sssd/ticket/1830

Fix authentication queue code for proxy auth We weren't decrementing the count of in-progress authentication request child processes when they completed successfully. With this patch, we will now guarantee that the process count is accurate and that queued requests will be started when a slot is freed up.

Suppress some 'may be used uninitialized' warnings Additionally the handling of errno and the errno_t return value of functions is fixed in krb5_common.c.

Split proxy.c into smaller files proxy.c was growing too large to manage (and some graphical development tools could no longer open it because of memory limitations).
