Reorganize functions to set options and flags, all flags can be set at once,
and there is no need to keep old falgs around as nothing ever used that for
anything useful.

Other components may need to connect sockets, the code here is generic enough
that with minimal modifications can be used for non-ldap connections too.
So create a sss_sockets.c/h utility file with all the non-ldap specific socket
setup functions and make them available for other uses.

This reverts commit 6e2822b151c21ce6e3287a0cf25d40e9f10a6127.
The function chown_debug_file is called before initialization
of debug stuff in sssd. Therefore variable debug_file cannot be
initialized. Therefore reverted commit completely turned off
changing owner of debug files. Side effect of this change
was that annoying error messages was not logged in case of
journald.

Adds support to get SELINUX context and make code more abstract so
that struct ucred (if availale) can be used w/o redefining uid,gid,pid to
int32. Also gives a layer of indirection that may come handy if we want
to improve the code further in the future.

AD expects its clients to renew the machine account password on a
regular basis, be default every 30 days. Even if a client does not renew
the password it might not cause issues because AD does not enforce the
renewal. But the password age might be used to identify unused machine
accounts in large environments which might get disabled or deleted
automatically.
With this patch SSSD calls an external program to check the age of the
machine account password and renew it if needed. Currently 'adcli' is
used as external program which is able to renew the password since
version 0.8.0.

Currently the SSSD default options like e.g. --debug-level are added
unconditionally to the command line options of a child process when
started with the child helper functions.
If a binary from a different source should be started as a child by SSSD
those options might not be known or used differently. This patch adds an
option to exec_child_ex() which allows to skip the default options and
only add specific options.

The krb5 provider was mapping KRB5KDC_ERR_CLIENT_REVOKED as
ERR_ACCOUNT_EXPIRED. This is incorrect as KRB5KDC_ERR_CLIENT_REVOKED is
returned by the KDC when an account lockout is in effect. When an account is
expired the kdc returns KRB5KDC_ERR_NAME_EXP.
Fix the mapping by adding a new ERR_ACCOUNT_LOCKOUT sssd_error code.

The state "struct sss_ldap_init_state" contains socket
created in function sss_ldap_init_send. We register callback
sdap_async_sys_connect_timeout for handling issue with connection
The tevent request "sss_ldap_init_send" is usually (nested) subrequest
of "struct resolve_service_state" related request created in fucntion
fo_resolve_service_send. Function fo_resolve_service_send also register
timeout callback fo_resolve_service_timeout to state "struct
resolve_service_state".
It might happen that fo_resolve_service_timeout will be called before
sss_ldap_init_send timeout and we could not handle tiemout error
for state "struct sss_ldap_init_state" and therefore created socket
was not closed.
We tried to release resources in function sdap_handle_release.
But the structure "struct sdap_handle" had not been initialized yet
with LDAP handle and therefore associated file descriptor could not be closed.

We need to stored two versions of name to the initgroups memory cache.
Otherwise it could be stored many times if sssd is configured with
case_sensitive = false. It would be impossible to invalidate all
version of names after user login. As a result of this wrong user
groups could be returned from initgroups memory cache.
Therefore we store raw name provided by glibc function
and internal sanitized fully qualified name,
which is unique for particular user.
This patch also increase average space for initgroups
because there are also stored two quite long names in case of
fq names.

Functions sss_mc_get_strs_offset and sss_mc_get_strs_len provides
data about strings for individual memory caches (passwd, ...)
Their are used in generic responder mmap cache code to find a record
in mmap cache (sss_mc_find_record). Data provided from functions sss_mc_get_*
are used for checking the validity of record. So in case of corrupted record
the whole mmap cache can be invalidated.
Functions sss_mc_get_strs_offset and sss_mc_get_strs_len did not provide
data for initgroups mmap cache and therefore particular record could not be
invalidated.

Currently in the default configuration
nss_check_name_of_well_known_sid() can only split fully-qualified names
in the user@domain.name style. DOM\user style names will cause an error
and terminate the whole request.
With this patch both styles can be handled by default, additionally if

ENOENT which can be handled more gracefully by the caller.
