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

84db813b9d Hook up TouchBegin/Update/End events
The are the same as device events internally but require the touch ID
separately from the detail.button field (the protocol uses the detail field
for the touch id).
For simpler integration of pointer emulation we need to set the
detail.button field while keeping the touchid around.

Add the three new touch event types to the various places in the server
where they need to be handled. The actual handling of the events is somewhat
more complicated in most places.

7d153f25be mieq: Provide better adaptability and diagnostics during mieq overflow
This patch changes from a static length event queue (512) to one that
starts at 128 and grows to 4096 as it overflows, logging each time it
grows.

This change also allows for multiple backtraces to be printed when the
server is wedged rather than just one.  This increased sampling should
help identify the true hog in cases where one backtrace might be
insufficient.

dc57f89959 Switch to use IsFloating()
This is not a straightforward search/replacement due to a long-standing
issue.

dev->u.master is the same field as dev->u.lastSlave. Thus, if dev is a master
device, a check for dev->u.master may give us false positives and false
negatives.
The switch to IsFloating() spells out these cases and modifies the
conditions accordingly to cover both cases.

31ab9f8860 mi: handle DGA subtypes when determining the master device.
The subtype in the DGA event is the core type and all ET_ event types (where
applicable) are identical to the core types. Thus the switch statement below
will work as required and assign the right master device.

Fixes a crasher bug on keyboard devices with valuators. If a device sends a
motion event while grabbed and a DGA client is active (but has not selected
input through DGA), the valuator event is posted through the VCK and
eventually results in a NULL-pointer dereference on dev->valuator.

b12d302df8 Input: rename DeviceIntRec->isMaster to ->type.
isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.

Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.

This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).

This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).
