Keith Packard 9838b7032e Introduce a consistent coding style
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)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

/*
* This module converts keysym values into the corresponding ISO 10646
* (UCS, Unicode) values.
*
* The array keysymtab[] contains pairs of X11 keysym values for graphical
* characters and the corresponding Unicode value. The function
* keysym2ucs() maps a keysym onto a Unicode value using a binary search,
* therefore keysymtab[] must remain SORTED by keysym value.
*
* The keysym -> UTF-8 conversion will hopefully one day be provided
* by Xlib via XmbLookupString() and should ideally not have to be
* done in X applications. But we are not there yet.
*
* We allow to represent any UCS character in the range U-00000000 to
* U-00FFFFFF by a keysym value in the range 0x01000000 to 0x01ffffff.
* This admittedly does not cover the entire 31-bit space of UCS, but
* it does cover all of the characters up to U-10FFFF, which can be
* represented by UTF-16, and more, and it is very unlikely that higher
* UCS codes will ever be assigned by ISO. So to get Unicode character
* U+ABCD you can directly use keysym 0x0100abcd.
*

*
* Special thanks to Richard Verhoeven <river@win.tue.nl> for preparing
* an initial draft of the mapping table.

* This software is in the public domain. Share and enjoy!
