Fix FlushClient to write extraBuf when provided (regression fix)

os: Hide the Connection{In,Out}put implementation details
Reviewed-by: Daniel Stone <daniel@fooishbar.org>
Signed-off-by: Adam Jackson <ajax@redhat.com>
the check for an empty output buffer was moved from one calling
location into the FlushClient implementation itself. However, this
neglected the possibility that additional data, in the form of
'extraBuf' would be passed to FlushClient from other code paths. If the
output buffer happened to be empty at that time, the extra data would
never be written to the client.
This is fixed by checking the total data to be written, which includes
both pending and extra data, instead of just the pending data.

os: Immediately queue initial WriteToClient
If we immediately put the WriteToClient() buffer into the socket's write
queue, not only do we benefit from sending the response back to client
earlier, but we also avoid the overhead of copying the data into our own
staging buffer and causing extra work in the next select(). The write is
effectively free as typically we may only send one reply per client per
select() call, so the cost of the FlushClient() is the same.
shmget10: 26400 -> 110000
getimage10: 25000 -> 108000
shmget500: 3160 -> 13500
getimage500: 1000 -> 1010
The knock-on effect is that on a mostly idle composited desktop, the CPU
overhead is dominated by the memmove in WriteToClient, which is in turn
eliminated by this patch.

os/xdmcp: Remove dead 'restart' code
The X server used to wait for the user to hit a key or move the mouse
before restarting the session after a keepalive failure. This,
presumably, was to avoid having the X server continuously spew XDMCP
protocol on the network while the XDM server was dead.
Switching into this state was removed from the server some time before
XFree86 4.3.99.16, so the remaining bits of code have been dead for
over a decade, and no-one ever noticed.

os: Add NotifyFd interfaces
This provides a callback-based interface to monitor file
descriptors beyond the usual client and device interfaces.
Modules within the server using file descriptors for reading and/or
writing can call
Bool SetNotifyFd(int fd, NotifyFdProcPtr notify_fd, int mask, void *data);
mask can be any combination of X_NOTIFY_READ and X_NOTIFY_WRITE.
When 'fd' becomes readable or writable, the notify_fd function will be
called with the 'fd', the ready conditions and 'data' values as arguments,
When the module no longer needs to monitor the fd, it will call
void RemoveNotifyFd(int fd);
RemoveNotifyFd may be called from the notify function.

os/xdmcp: Just send XDMCP keepalive packets once every three minutes
There was a complicated scheme to increase the time between keepalives
from 3 minutes up to as much as 24 hours in an attempt to reduce
network traffic from idle X terminals. X terminals receiving X
traffic, or receiving user input would use the 3 minute value; X
terminals without any network traffic would use a longer value.
However, this was actually broken -- any activity in the X server,
either client requests or user input, would end up resetting the
keepalive timeout, so a user mashing on the keyboard would never
discover that the XDMCP master had disappeared and have the session
terminated, which was precisely the design goal of the XDMCP keepalive
mechanism.
Instead of attempting to fix this, accept the cost of a pair of XDMCP
packets once every three minutes and just perform keepalives
regularly.
This will also make reworking the block and wakeup handler APIs to
eliminate select masks easier.

Content of that file is now hard-coded.
Adopting an exact copy of os/oscolor.c from X.org leads to this compiler warning:
```
oscolor.c:844:1: warning: string length ‘7614’ is greater than the length ‘4095’ ISO C99 compilers are required to support [-Woverlength-strings]
};
^
```
This will be address later in coordination with X.org.
Note: there is a tiny change in oscolor.c as we ship it. The original X.org file includes <X11/keysym.h> which seems
unneeded. We drop that one line from oscolor.c.

A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

Casting return to (void) was used to tell lint that you intended
to ignore the return value, so it didn't warn you about it.
Casting the third argument to (char *) was used as the most generic
pointer type in the days before compilers supported C89 (void *)
(except for a couple places it's used for byte-sized pointer math).

This matches the test in TryClientEvents, and is a superset of tests
done by the callers of these functions. The consequence of forgetting
these tests is a server crash, so they're always desirable. In my
opinion, it's better to not require the callers to remember to do these
checks.
For callers that don't do very much work before calling WriteToClient or
WriteEventsToClient, I've removed the redundant checks.

render: Fix byteswapping of gradient stops
The function swapStops repeatedly swaps the color components as
CARD16, but incorrectly steps over them as if they were CARD32.
This causes half of the stops not to be swapped at all and some
unrelated data be swapped instead.

Clean {X,XNF}{alloc,calloc,realloc,free,strdup} from pre-C89 baggage
C89 guarantees alignment of pointers returned from malloc/calloc/realloc, so
stop fiddling with alignment manually and just pass the arguments to library
functions.
Also convert silent error when negative size is passed into function into
warning in log file.
