Previously, if realloc failed to increase the size, we'd still
record that we had allocated the larger size, but the pointer
to it would be NULL, causing future calls to be broken, and the
previous allocation to be lost/leaked.

Previous code seemed to assume that printf("%s", NULL) would result
in a 0-length string, not "(null)" or similar, but since there's no
point looking for files in "(null)/filepath...", instead we just
skip over NULL entries in search paths when generating file names.
In the *DirName() functions, this effectively just moves the "bail on
NULL in arg[i]" check up from the later code that assigned it to targetdir
and then bailed if that was NULL.
Not sure how there ever could be a NULL in arg[i], given the current
implementation of XlcParsePath, but it's easy enough to check once and
reject up front instead of on every reference.

place.
When synthesized key events are sent on commit XIM sets the 'fabricated'
flag so that the keypress handler knows that these were not real events.
This also happens when committing due to the loss of focus. However in this
case the keypress/release filters which consume and unset this flag are no
longer in the filter chain.
So the flag is erronously set when a real keyboard event is received after
focus has been regained. So the first event is wrongly treated as a
fabricated key in the keypress handler which will at the same time reset
the flag so the second key event is treated correctly.
This fix only sets the flag when at least one of the keyboard filters is in
place.
How to reproduce this bug: run scim, choose a Japanese input method start
two instances of xterm: start typing in one xterm (this should pop up an
IM window). Without comitting (hitting 'enter') move focus to the other
xterm, then move focus back. Start typing again. The first character will
be committed immediately without popping up an input window.
With this fix this behavior is gone.

Two users of GetReqExtra pass arbitrarily sized allocations from the
caller (ModMap and Host). Adjust _XGetRequest() (called by the GetReqExtra
macro) to double-check the requested length and invalidate "req" when
this happens. Users of GetReqExtra passing lengths greater than the Xlib
buffer size (normally 16K) must check "req" and fail gracefully instead
of crashing.
Any callers of GetReqExtra that do not check "req" for NULL
will experience this change, in the pathological case, as a NULL
dereference instead of a buffer overflow. This is an improvement, but
the documentation for GetReqExtra has been updated to reflect the need
to check the value of "req" after the call.

[For all of these, LONG_MAX was the correct value to prevent overflows
for the recent CVEs. Lowering to INT_MAX catches buggy replies from
the server that 32-bit clients would reject but 64-bit would accept,
so we catch bugs sooner, and really, no sane & working server should
ever report more than 2gb of extension names, font path entries,
key modifier maps, etc. -alan- ]

clang complained (correctly):
warning: comparison of constant 768614336404564650 with expression
of type 'CARD32' (aka 'unsigned int') is always true
[-Wtautological-constant-out-of-range-compare]
[While LONG_MAX is correct, since it's used in size_t math, the
numbers have to be limited to 32-bit range to be usable by 32-bit
clients, and values beyond that range are far more likely to be
bugs in the data from the server than valid numbers of characters
in a font. -alan- ]

It seems useless to do that since the code tests for both source
length and destination to be non-zero. This fixes a cut'n'paste

This commit looks a bit crazy at first glance. It (re-)introduces lots
of whitespaces and bad formatting.
Explanation: Backporting upstream changes lead to commits being
applied out of order. This meant a lot of manual intervention which in
turn lead to slight differences between upstream and NX.
With this commit these slight differences are minimized which will be
of great help when adding further upstream patches.

Called from XrmGetFileDatabase() which gets called from InitDefaults()
which gets the filename from getenv ("XENVIRONMENT")
If file is exactly 0xffffffff bytes long (or longer and truncates to
0xffffffff, on implementations where off_t is larger than an int),
then size may be set to a value which overflows causing less memory
to be allocated than is written to by the following read() call.
size is left limited to an int, because if your Xresources file is
larger than 2gb, you're very definitely doing it wrong.

While the C standard technically allows for the compiler to translate
pointer = 0 or pointer = NULL into something other than filling the
pointer address with 0 bytes, the rest of the Xlib code already assumes
that calloc initializes any pointers in the struct to NULL, and there
are no known systems supported by X.Org where this is not true.
