Comment some places where it's OK to unref a message despite holding locks
In general, dbus_message_unref should be avoided while holding locks,
because it can invoke arbitrary user callbacks (via attached data, or
via DBusCounter).

man pages: replace all unescaped hyphen/minus characters with \-
In a man page, "-" officially means a typographical (Unicode) hyphen,
which frequently breaks the ability to copy and paste code examples from
a man page. "\-" means the ASCII hyphen/minus character. See
<http://lintian.debian.org/tags/hyphen-used-as-minus-sign.html> for
more details.
Rather than trying to distinguish between hyphens, em-dashes and
hyphen/minus, I just replaced all ambiguous hyphens with \- by applying
this vim command repeatedly until it didn't find anything:
%s/\(^\|[^\\]\)-/\1\\-/g

Use EXEEXT when running tests from another directory, and skip bus-test-launch-helper on non-Unix
This is necessary when cross-compiling from Linux to mingw32 and running
the resulting tests under Wine. (This partially works! Some tests fail,
though.)

Build docs after running tests, and remove redundant DIST_SUBDIRS
If DIST_SUBDIRS isn't set, it defaults to SUBDIRS, so it's just noise.
Running tests before building documentation is an easy way to speed up the
hack/make check/fix cycle, by not wasting time rebuilding the
documentation (which is often slow) until all the tests compile and pass.

_dbus_connect_tcp_socket_with_nonce: don't create an extra fd (which is then leaked)
This block should have been deleted in 2007, when IPv6 support was added:
previously, the fd allocated at the beginning of the function was used
for connect(), but for IPv6 support, the socket() call has to be inside
the loop over getaddrinfo() results so its address family can be changed.

Remove maximum length field from DBusString
The source code says it's "a historical artifact from a feature that
turned out to be dumb". Respond accordingly!
This reduces sizeof (DBusString) by 20% on ILP32 architectures, which
can't hurt. (No reduction on LP64 architectures that align pointers
naturally, unfortunately.)

DBusLoop: store watches in a hash table keyed by fd
This means we don't need to build up the watches_for_fds array, because
it's quick to find the watches based on the fd.
This also fixes fd.o #23194, because we only put each fd in the
array of DBusPollFD once, with the union of all its watches' flags; we
can no longer get more entries in the array than our number of file
descriptors, which is capped at our RLIMIT_NOFILE, so we can't get
EINVAL from poll(2).

DBusLoop: move OOM flag in watches inside the DBusWatch
This will eventually let us maintain a DBusPollFD[] of just the active

WatchCallback can go away, because it only contains a refcount, a
now-useless type, and a watch that already has its own refcount.
This doesn't take any more memory for DBusWatch when not using DBusLoop
(e.g. in client/service code or bindings), because we're just using more
bits in an existing bitfield.

DBusLoop: remove second layer of watch callbacks where possible

now, just migrate it to a new _dbus_loop_add_watch_full which preserves
the second-layer callback.

DBusLoop: remove a layer of pointless abstraction around timeouts
Instead of supplying 8 tiny wrapper functions around dbus_timeout_handle,
each with a user_data parameter that's a potentially unsafe borrowed
pointer but isn't actually used, we can call dbus_timeout_handle directly
and save a lot of trouble.
One of the wrappers previously called dbus_timeout_handle repeatedly
if it returned FALSE to indicate OOM, but that timeout's handler never
actually returned FALSE, so there was no practical effect. The rest just
ignore the return, which is documented as OK to do.

DBusConnection: ref the connection in the timeout handler
client_timeout_callback in bus/test.c refs the connection across the
timeout invocation, which looks suspiciously like a workaround. If we
make the timeout handler itself ref the connection, we won't need that,
and can simplify timeout handling drastically.
