build-sys: don't install sd-shutdown.h, it is a drop-in header like sd-readahead.h
update TODO
pam: the DECIMAL_STR_MAX macro is awesome, let's use it
util: add circle to special chars we can draw
socket-proxyd: no need to redefine sockaddr union
api: replace manual C++ guards by macros
shutdown: as sd-shutdown.h is a drop-in header it should not include any other headers of ours
activate: print a nice message if no fd to listen on was specified
socket-proxy: actually properly keep track of connections
bus: message_append_basic() - allow string == NULL
bus: also check for NULL when appending trivial types
build-sys: add a make target to look for undocumented symbols

With super-pretty output!
man: add docs for sd_is_special() and some man page symlinks
rtnl: add Makefile symlink
bus: allow reading empty arrays with sd_bus_message_read_array()
bus: fix output of bus_message_dump()
bus: bus_message_read_strv_extend() should return 1 on success

Like all other message read calls bus_message_read_strv_extend() needs
to return 1 on sucess, and 0 on end of array.
bus: fix bus_print_property with strv
bus: mark sd_bus_message_at_end public
bus: add APIs to easily query string and strv properties
