generated man pages: build without hard coded extension
The automake MAN primary requires a hard coded extension to build
man pages. Let's avoid that as the extension number may vary by platform.
Take advantage of the fact that the man directory only contains man pages.
Wildcards are not supported by Automake but it happens to work
sufficiently well here.
Normally xorg build man pages by converting a source .man file to a
target file with the extension number. That would be too many files
in this case.

Force XCB event structures with 64-bit extended fields to be packed.
With the advent of the Present extension, some events (such as
PresentCompleteNotify) now use native 64-bit types on the wire.
For XGE events, we insert an extra "uint32_t full_sequence" field
immediately after the first 32 bytes of data. Normally, this causes
the subsequent fields to be shifted over by 4 bytes, and the structure
to grow in size by 4 bytes. Everything works fine.
However, if event contains 64-bit extended fields, this may result in
the compiler adding an extra 4 bytes of padding so that those fields
remain aligned on 64-bit boundaries. This causes the structure to grow
by 8 bytes, not 4. Unfortunately, XCB doesn't realize this, and
always believes that the length only increased by 4. read_packet()
then fails to malloc enough memory to hold the event, and the event
processing code uses the wrong offsets.
To fix this, mark any event structures containing 64-bit extended
fields with __attribute__((__packed__)).
v2: Use any(...) instead of True in (...), as suggested by
Daniel Martin.
v3 (Alan Coopersmith): Fix build with Solaris Studio 12.3 by moving the
attribute to after the structure definition.

c_client.py: Fix _sizeof() functions
Currently, it is not possible to correctly iterate over the replies of
some requests. For example, the list of XIDeviceInfo returned by
the XIQueryDevice request from xinput2 is read as garbage starting from
the second entry.
The culprits are the _sizeof() used by the iterators. In the above case:
int
xcb_input_xi_device_info_sizeof (const void *_buffer /**< */)
{
char *xcb_tmp = (char *)_buffer;
[...]
unsigned int xcb_block_len = 0;
[...]
xcb_block_len += sizeof(xcb_input_xi_device_info_t);
xcb_tmp += xcb_block_len;
/* name */
xcb_block_len += (((_aux->name_len + 3) / 4) * 4) * sizeof(char);
xcb_tmp += xcb_block_len;
[...]
}
The problem here is that `xcb_block_len` is not zero'd right above the
`/* name */` comment, causing `xcb_tmp` to be incremented by
`sizeof(xcb_input_xi_device_info_t)` twice. The returned size is too
large.

Fix poll() if POLLIN == ROLLRDNORM|POLLRDBAND
It seems like POLLIN is specified as equivalent to POLLRDNORM | POLLRDBAND. Some
systems (e.g. QNX and HP-UX) take this literaly and have POLLIN defined as the
above bit combination. Other systems (e.g. Linux) have POLLIN as just a single
bit.
This means that if no out-of-band data is available (which should never be the
case), the result of poll() will not fulfil (fd.revents & POLLIN) == POLLIN on
QNX, because the POLLRDBAND bit is not set.
In other words, even though poll() signaled that the fd is readable, xcb would
not read from the file descriptor.
Fix this by checking if any bits from POLLIN are set in the result of poll(),
instead of all of them.

fix deadlock with xcb_take_socket/return_socket v3
To prevent different threads from stealing the socket from each other the
caller of "xcb_take_socket" must hold a lock that is also acquired in
"return_socket". Unfortunately xcb tries to prevent calling return_socket
from multiple threads and this can lead to a deadlock situation.
A simple example:
- X11 has taken the socket
- Thread A has locked the display.
- Thread B does xcb_no_operation() and thus ends up in libX11's return_socket(),
waiting for the display lock.
- Thread A calls e.g. xcb_no_operation(), too, ends up in return_socket() and
because socket_moving == 1, ends up waiting for thread B
=> Deadlock
This patch allows calling return_socket from different threads at the same time
an so resolves the deadlock situation.

Fix a busy loop on BSD and Mac OS
On FreeBSD MSG_WAITALL on a non-blocking socket fails immediately if less bytes
than were asked for are available. This is different than the behavior on linux
where as many bytes as are available are returned in this case. Other OS
apparently follow the FreeBSD behavior.
_xcb_in_read() is used to fill xcb's read buffer, thus this function will call
recv() with a big length argument (xcb's read buffer is by default 16 KiB
large). That many bytes are highly unlikely to be available in the kernel
buffer.
This means that _xcb_in_read() always failed on FreeBSD. Since the socket was
still signaled as readable by poll(), this bug even resulted in a busy loop.
The same issue is present in read_block(), but here it is slightly different.
read_block() is called when we read the first few bytes of an event or a reply,
so that we already know its length. This means that we should be able to use
MSG_WAITALL here, because we know how many bytes there have to be.
However, that function could busy loop, too, when only the first few bytes of
the packet were sent while the rest is stuck somewhere on the way to us. Thus,
MSG_WAITALL should be removed here, too.

Fix a dead-lock due to xcb_poll_for_reply
Imagine two threads:
Thread#1: for(;;) { xcb_get_input_focus_reply(c, xcb_get_input_focus(c), 0); }
Thread#2: for(;;) { xcb_poll_for_event(c); }
Since xcb_poll_for_event() calls _xcb_in_read() directly without synchronizing
with any other readers, this causes two threads to end up calling recv() at the
same time. We now have a race because any of these two threads could get read
the GetInputFocus reply.
If thread#2 reads this reply, it will be put in the appropriate queue and
thread#1 will still be stuck in recv(), although its reply was already received.
If no other reply or event causes this thread to wake up, the process deadlocks.
To fix this, we have to make sure that there is only ever one thread reading
from the connection. The obvious solution is to check in poll_for_next_event()
if another thread is already reading (in which case c->in.reading != 0) and not
to read from the wire in this case.
This solution is actually correct if we assume that the other thread is blocked
in poll() which means there isn't any data which can be read. Since we already
checked that there is no event in the queue this means that
poll_for_next_event() didn't find any event to return.
There might be a small race here where the other thread already determined that
there is data to read, but it still has to wait for c->iolock. However, this
means that the next poll_for_next_event() will be able to read the event, so
this shouldn't cause any problems.

Compute alignment correctly
The code previously assumed that everything has to be aligned to a 4 byte
boundary. This assumption is wrong as e.g. the STR struct from xproto shows.
Instead, each type has to be aligned to its natural alignment. So a char doesn't
need any alignment, a INT16 gets aligned to a 2-byte-boundary and a INT32 gets
the old 4 byte alignment.
I'm not 100% sure that this commit is correct, but some quick tests with awesome

resolving localhost (or 127.0.0.0/8 or ::1). Also, as per RFC 3493,
loopback addresses are not considered as valid addresses when
determining whether to return IPv4 or IPv6 addresses.
As per mailing-list discussion on the xcb list started with message
20110813215405.
5818a0c1@x200, the AI_ADDRCONFIG flag is there for historical
reasons:
In the old days, the "default on-link" assumption in IPv6 made the flag vey
much indispensable for dual-stack hosts on IPv4-only networks. Without it,
there would be long timeouts trying non-existent IPv6 connectivity. Nowadays,
this assumption has been flagged as historic bad practice by IETF, and hosts
should have been updated to not make it anymore.
Then AI_ADDRCONFIG became mostly cosmetic: it avoids phony "Protocol family
not supported" or "Host unreachable" errors while trying to connect to a dual-
stack mode from a host with no support for source address selection.
Nowadays, on up-to-date systems, this flag is completely useless. Then again,
I understood only the very latest MacOS release is "up-to-date" with this
definition.

Insert, not append explicit xcbgen dir python path
If a the path to the xcb python generate libs is
explicitly specified to c_client.py, insert it in
the python path list just after the local dir entry,
rather than appending it to the existing paths.
This keeps a global/distro install of xcb from
overriding a local build of the xcb proto files.

Add support for building with Python 3
Python 3 introduces some language changes that cause issues when running
c_client.py. This also breaks compatibility with Python 2.5 since it does not
support the "as" statement in try/except blocks and does not have reduce() in
the functools package.
The main changes are:
* try/except blocks require `except ... as ...:` to resolve syntactical ambiguity
* map() and filter() return iterators rather than lists in Python 3
* reduce() is now in functools package (and not built-in in Python 3)
* Dictionaries don't have a has_key() method in Python 3
* None and int types can't be directly compared in Python 3
* print() is a statement in Python 3
See http://diveintopython3.org/porting-code-to-python-3-with-2to3.html and
PEP-3110 for details.
Verified on Python 2.6.5 and 3.1.3.

Revert "Introduce xcb_wait_for_event_until, for consuming responses in wire-order."
This function was intended to allow libX11 to fix a multi-threaded hang,
but the corresponding libX11 patch caused single-threaded apps to spin
sometimes. Since I've retracted that patch, this patch has no users and
shouldn't go into a release unless/until that changes.
