The xnfreallocarray was added along (and just as an alias to) XNFreallocarray
back a decade ago. It's just used in a few places and it's only saves us from
passing the first parameter (NULL), so the actual benefit isn't really huge.
No (known) driver is using it, so the macro can be dropped entirely.

- Don't remove the BiosBase keyword from the config parser since that

This is a really awkward interface, since we're calling it well before
the driver knows what device it's going to drive. Drivers with both KMS
and UMS support therefore don't know whether to say they need I/O port
access or not, and have to assume they do.
With this change we now call it only to query whether port access might
be needed; we don't use that to determine whether to call a driver's
probe function or not, instead we call them unconditionally. If the
driver doesn't check whether port access was enabled, they might crash
ungracefully. To accomodate this, we move xorgHWAccess to be explicitly
intentionally exported (sigh xf86Priv.h) so that drivers can check that
before they attempt port access.
v2: Move initial xf86EnableIO() nearer the logic that determines whether
to call it, suggested by Simon Farnsworth.

This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:
-bap
-psl
-T PrivatePtr
-T pmWait
-T _XFUNCPROTOBEGIN
-T _XFUNCPROTOEND
-T _X_EXPORT
The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.
The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.
The comparison was done with this script:
dir1=$1
dir2=$2
for dir in $dir1 $dir2; do
(cd $dir && find . -name '*.o' | while read file; do
dir=`dirname $file`
base=`basename $file .o`
dump=$dir/$base.dump
objdump -d $file > $dump
done)
