launch_daemon: We can now talk to the authentication manager.

* When creating the port of the registrar's authentication manager, we
now set it manually, so that the user/group functions work.
* This allows LaunchDaemon::_StartSession() to set up the user, and
groups as needed.

registrar: implemented auth port via launch_daemon.

* get_roster_port_name() is no longer needed.
* This also removes the app_server restart code from the debug
server -- this will be done by the launch_daemon in the future.

Introduce __set_errno() throughout libroot.

* add errno_private.h, which defines the __set_errno() macro with
and without tracing
* instead of setting errno manually, all libroot's code now invokes
__set_errno(), which makes it much easier to trace changes to errno
* redirect glibc's use of __set_errno() to our own version

rest of the patch by Kaliber in ticket #5875.

* Private libroot locking primitives:
- Reimplemented mutex to use the _kern_mutex*() syscalls.
- The initializer functions cannot fail anymore -- changed their return type
to void.
- Changed the initializer function semantics to not copy the name by default
anymore (as in the kernel). Also added *_etc() versions of them that take an
additional flags.
- Added static initializer macros.
- Made the mutex (and thus recursive_lock) lock functions non-interruptable.
- Got rid of the "lazy" version. They are no longer needed, since the
initialization of the standard types can be done statically and cannot fail.
* Adjusted libroot, runtime loader, and other code using the private libroot
locking primitives to the new semantics.
* pthreads mutexes and condition variables:
- Reimplemented using the _kern_mutex*() syscalls.
- Consistently use POSIX error codes.
- Fixed some not quite POSIX compliant behavior.

Replace semaphores/benaphores in the env, fork, and user/group code by lazy
mutexes.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@34340 a95241bf-73f2-0310-859d-f6bbb57e9c96

Added missing spwd::sp_lstchg field.

* Reorganized the passwd and group support: A dedicated thread in the
registrar provides access to the DBs via a port message based
protocol. The functions in libroot just ask the registrar now.
* Added Linuxish shadow passwd support. No putspent() though -- we'll
provide private functions.

* gcc4 build fix


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24756 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Replaced the dummy implementations of the <grp.h> and <pwd.h>
functions by ones reading /etc/{group,passwd}.
* Added quasi-standard getpwent_r() and getgrent_r().
* Added _SC_GETGR_R_SIZE_MAX and _SC_GETPW_R_SIZE_MAX sysconf()
constants.
* Moved initgroups() and getgrouplist() definition to grp.cpp. They use
the same backend as the <grp.h> functions.
* Set the permissions of files created by the build system to what they
should be on the image (executables: 755, others: 644). Otherwise only
root could do anything under Haiku.
* Added build system variables HAIKU_ROOT_USER_NAME and
HAIKU_ROOT_USER_REAL_NAME to customize name and real name of Haiku's
root user.
* Added build system rules AddUserToHaikuImage and AddGroupToHaikuImage
for adding additional users and groups (by default only root user and
group and a "users" group are created).
* Adjusted BIND port and coreutils config.h files according to what
features have become available.
* Fixed HAIKU_DOCUMENTATION_OBJECT_DIR definition. Untested, but it used
a wrong variable name before.
