    etc. It's initialized if (extents), and then only read if (extents),

They were just aliases to already existing defines and were not used
stringently. So we had mix of aliased and non-aliased uses which is
confusing when trying to understand the code...

This was eventually replaced by nxagentAddConfiguredWindow(pWin,
CW_Map) some lines below which is just leading to the same code being
executed some time later.

(nxagentAddConfiguredWindow() will add a window to a
list. nxagentFlushConfiguredWindow() is called at certain points to
update all windows in that list in one go. "update" here means calling
XConfigureWindow() or XMapWindow() on the real display.)

We are not using any alloc function that respects that variable, so
lets drop it. Backport of this commit:

    Remove the Must_have_memory hack.

    Also remove an astonishing amount of misunderstanding of how casts work.

The only left function is identical to the one in mi/miexpose.c.

We do not even know what theme this is and it is probably not relevant
nowadays.

miPaintWindow() was identical to the version in miexpose.c except
for some unitialized variable fixes. As these also should be in
upstream code we add them there (Note: Xorg never fixed this but
totally rewrote the miPaintWindow() later on.)

This allows us to totally drop our special version of miPaintWindow().

It is (functionally) identical to our code, so why have
duplicate code?

Not sure how it came to this situation, but the following commit is
partly contained in our version of the code. Some lines had not been

    os: Fix BigReq ignoring when another request is pending

    Commit cf88363db0ebb42df7cc286b85d30d7898aea840 fixed the handling of
    BigReq requests that are way too large and handles the case where the
    read() syscall returns a short read.  However, it neglected to handle
    the case where it returns a long read, which happens when the client
    has another request in the queue after the bogus large one.

    Handle the long read case by subtracting the smaller of 'needed' and
    'gotnow' from oci->ignoreBytes.  If needed < gotnow, simply subtract
    the two, leaving gotnow equal to the number of extra bytes read.
    Since the code immediately following the (oci->ignoreBytes > 0) block
    tries to handle the next request, advance oci->bufptr immediately
    instead of setting oci->lenLastReq and letting the next call to
    ReadRequestFromClient do it.

    Fixes the XTS pChangeKeyboardMapping-3 test.

CheckMotion() had been commented in
add88193 as it looked identical to the
version from dix/events.c except for some commented code. But this
based (probably) on a thinko - code that had been disabled by NX
became active again this way. Fix this by removing the comments and
by adding #ifdef/else to emphasize the difference.
