Using PRId64, etc. to print dbus_int64_t or dbus_uint64_t is not 100%
portable. On platforms where both long and long long are 64-bit (such as
Linux and macOS), we will prefer to define dbus_int64_t as long.
If the operating system has chosen to define int64_t as long long,
which is apparently the case on macOS, then the compiler can warn that
we are passing a long argument to PRId64, which is "lld" and therefore
expects a long long argument (even though that ends up with the same
bit-pattern being used).
We can't necessarily just use int64_t and uint64_t directly, even if all
our supported platforms have them available now, because swapping
dbus_int64_t between long and long long might change C++ name mangling,
causing ABI breaks in third-party libraries if they define C++ functions
that take a dbus_int64_t argument.

Some editors automatically remove trailing blank lines, or
automatically add a trailing newline to avoid having a trailing
non-blank line that is not terminated by a newline. To avoid unrelated
whitespace changes when users of such editors contribute to dbus,
let's pre-emptively normalize all files.
Unlike more intrusive whitespace normalization like removing trailing
whitespace from each line, this seems unlikely to cause significant
issues with cherry-picking changes to stable branches.

This fixes signedness mismatch warnings on platforms where socklen_t
is unsigned, notably Linux (where it's an unsigned int).
We still use int for the fallback case where the platform does not
define socklen_t, because that was the traditional (pre-POSIX) type:

Use the standard C99 PRI*64 macros instead of checking for specific GNU
libc version. We also specifically check for windows which does not have
proper C99 support.
This fixes printing of int64 on non-GNU 32 bit systems (like musl libc).

dbus-send could already pretty-print bytestrings that do not have
\0 termination, but those are awkward to work with (they need copying),
so they are now discouraged. Teach it to print bytestrings that
do have \0 termination as well.
In the process, rewrite this part of the message parser
to use dbus_message_iter_get_fixed_array(), which is the Right way
to get arrays of numbers out of a message.

There were already defines for formatting pids and uids, so use those.
In the case where we don't have a format specifier for 64 bit, print

We were previously using -Wno-format because we didn't have
a #define for DBUS_INT64_MODIFIER, which was really lame because
it easily hid problems.
For now, just define it if we're on glibc; this is obviously
not strictly correct but it's safe, because the formatting
is only used in DBUS_VERBOSE mode, and in tools/dbus-monitor.
Ideally we get the the glib code relicensed.
In practice, ay seems to be used mostly for binary data (in which case,
hex output is fine) or for Unix file paths (because they may be
non-UTF-8) and similar human-readable strings. So let's print the latter
similarly to strings.
Previously dbus_message_iter_get_arg_type() was called twice: once in
the loop condition to update 'current_type', and once to check if the
loop will run again. This patch moves updating current_type to the end
of the loop body.

This patch is huge, but the public API change is not
really large. The set of D-BUS types has changed somewhat,
and the arg "getters" are more geared toward language bindings;
they don't make a copy, etc.
There are also some known issues. See these emails for details
on this huge patch:
