In condvar wait functions, set the holder back before restoring count
Before this fix, there is a racing condition. The previous owner thread
can get into the mutex without proper locking by passing the lock owner
check in mutex_lock function.

Bug 18121 - Use a monotonic clock for pthread timeouts
Patch based on one from Keith Mok <ek9852@gmail.com>, some
followup work from Janne Karhunen <Janne.Karhunen@gmail.com>.
We don't want condition variable timeouts to be affected by the system clock.
Use the POSIX CLOCK_MONOTONIC if available.

* dbus/dbus-sysdeps.c (_dbus_set_errno_to_zero)
(_dbus_get_is_errno_nonzero, _dbus_get_is_errno_eintr)
(_dbus_strerror_from_errno): family of functions to abstract
errno, though these are somewhat bogus (really we should make our
socket wrappers not use errno probably - the issue is that any
usage of errno that isn't socket-related probably is not
cross-platform, so should either be in a unix-only file that can
use errno directly, or is a bug - these general errno wrappers
hide issues of this nature in non-socket code, while
socket-specific API changes would not since sockets are allowed
cross-platform)

* dbus/dbus-sysdeps-pthread.c (_dbus_pthread_mutex_lock,
_dbus_pthread_condvar_wait,
_dbus_pthread_condvar_wait_timeout): set pmutex->holder to
pthread_self() after coming back from a conditional variable
wait as well as in one codepath where it was forgotten.
Approved by: Havoc Pennington.

* dbus/dbus-test.c: enclose more of the file in the
DBUS_BUILD_TESTS check.
* dbus/dbus-sysdeps-pthread.c (PTHREAD_CHECK): fix for
DBUS_DISABLE_ASSERT case.
* dbus/dbus-connection.c (dbus_connection_get_unix_user): document
that it only works on the server side
* dbus/dbus-bus.c: add a global lock covering the BusData we
attach to each connection
(internal_bus_get): lock our access to the BusData
(dbus_bus_register): lock the entire registration process
with _DBUS_LOCK(bus_datas). If we get the lock and
registration is already complete, silently return (vs. previous
behavior of aborting).
(dbus_bus_set_unique_name): lock the BusData
(dbus_bus_get_unique_name): lock the BusData

* dbus/dbus-sysdeps-pthread.c: make the "count" and "holder"
variables volatile, suggested by Thiago. Document struct fields.
(PTHREAD_CHECK): remove pthread error checking if assertions are
disabled, should reduce the no-assertions case to the bare
minimum code.

* doc/dbus-specification.xml: clarify the UUID text slightly
* dbus/dbus-sysdeps-pthread.c: check for and mostly abort on
pthread errors. Add DBusMutexPThread and DBusCondVarPThread
in preparation for being able to extend them for e.g. recursive
mutexes.

condition variables relate to recursive mutexes.
* dbus/dbus-sysdeps-pthread.c, dbus/dbus-sysdeps-win-thread.c,
dbus/dbus-threads.c: Split the platforms-specific thread
implementations into their own files.
* dbus/dbus-sysdeps-pthread.c
(_dbus_pthread_condvar_wait_timeout): invert the return value, it
was backward. Not that anything uses it.
