* dbus/dbus-types.h: add dbus_unichar
* dbus/dbus-internals.c (_dbus_verbose): use _dbus_getenv
* dbus/dbus-connection.c (dbus_connection_send_message): return
TRUE on success
* dbus/dbus-transport.c: include dbus-watch.h
* dbus/dbus-connection.c: include dbus-message-internal.h
* HACKING: add file with coding guidelines stuff.
* dbus/dbus-string.h, dbus/dbus-string.c: Encapsulate all string
handling here, for security purposes (as in vsftpd). Not actually
using this class yet.
* dbus/dbus-sysdeps.h, dbus/dbus-sysdeps.c: Encapsulate all
system/libc usage here, as in vsftpd, for ease of auditing (and
should also simplify portability). Haven't actually moved all the
system/libc usage into here yet.
