When uploading bits to a texture which need reformatting to match a
supported GL format, a temporary buffer is allocated to hold the
reformatted bits. This gets freed in the general path, but is not
freed in the fast path because that includes an early return before
the call to free.
This patch removes the early return and places the general case under
an 'else' block, so that both paths reach the call to free.

glamor_color_convert_to_bits() returns its second argument on
success, NULL on error, and need_free_bits already makes sure that
"bits" aliasing converted_bits is freed in the success case.
Looks like the memory leak that was supposed to be fixed in
6e50bfa706 only occurred in the error
case.

In the unlikely event of a failure in creating processes, signal
masks will fall from the panels above you. Secure your mask before
telling your child what to do, since it won't exist, and you will
instead cause the server itself to be replaced by a shell running
the target program.

On gcc, __attribute__((cold)) means:
- consider calls to the function to be unlikely for branch prediction
- optimize the function for size
- emit the function in a dedicated cold text section
It's not worth deleting these routines even though there are no longer
in-tree consumers, but we can at least keep them out of i$ at runtime.

This does have one semantic change. FixesCreateRegionFromPicture used to
throw BadImplementation if you tried to create a region from a picture
with no client clip. I changed that to BadMatch here since that more

make -j 8 check was sporadically failing in different xi2 tests.
After adding the asserts in the previous commit to catch xkb failure
it became easier to catch the failures and see that multiple tests
were running at once trying to write to /tmp/server-(null).xkm and
then delete it, and interfering with each other.
Putting a unique string into the display variable let them each write
to their own file and not interfere with others.
v2: Fix Linux bits:
Add #include <errno.h> to get a declaration of
program_invocation_name on Linux.
Use only the last portion of the pathname so that the resulting
display name doesn't contain any slashes.
v3: use program_invocation_short_name on Linux
This is the same as program_invocation_name, except is has
stripped off any path prefix.

I was getting segfaults in xi2 tests from trying to copy XKB keyboard
state to NULL pointers with a stack of:
key=key@entry=0) at xkbActions.c:1189
sendevent=sendevent@entry=0 '\000') at devices.c:420
at protocol-xiquerydevice.c:338
which turned out to be due to xkbcomp failure, which was logged in the
test logs as:
XKB: Failed to compile keymap
Keyboard initialization failed. This could be a missing or incorrect setup of xkeyboard-config.
but which was overlooked because the ActivateDevice() return code wasn't
checked and the tests went forward assuming the structures were all
correctly initialized. This catches the failure closer to the point of
failure, to save debugging time.
