Write a "test-profile" that does echo client-server with threads;
profile reveals lock contention, memcpy/realloc of buffers, and
UTF-8 validation as hot spots. 20% of lock contention eliminated
with dbus_atomic_inc/dec implementation on x86. Much remaining
contention is global mempool locks for GList and DBusList.
* dbus/dbus-sysdeps.c (_dbus_atomic_inc, _dbus_atomic_dec): add
x86 implementation
* dbus/dbus-connection.c (struct DBusConnection): use
dbus_atomic_t for the reference count
* dbus/dbus-message.c (struct DBusMessage): declare
dbus_atomic_t values as volatile
* configure.in: code to detect ability to use atomic integer
operations in assembly, from GLib patch
* dbus/dbus-internals.c (_dbus_verbose_real): call getpid every
time, tired of it being wrong in threads and forked processes
* glib/test-profile.c: a little program to bounce messages back
and forth between threads and eat CPU
* dbus/dbus-connection.c: add debug spew macros for debugging
thread locks; include config.h at top; fix deadlock in
dbus_connection_flush()
