Key points:
1. a TQPostEventList can now have an associated mutex, which is used in case of the global post event list (GPEL)
2. the lifetime of the GPEL is no longer associated to the lifetime of the TQApplication object, but rather extended to the lifetime of the main thread. The GPEL is a static local initialized on first access and destroyed when the global static object destructor is invoked
3. access to the GPEL after the TQApplication object has been destroyed has been minimized by protecting calls in ~TQObject() and ~TQWidget().
4. special care was taken not to affect performances or unnecessarily create tons of unused TQMutexes
This replaces PR #182. Technically it is still possibly unsafe due to the order of destruction of the globat static objects not being guaranteed across multiple compilation units, but the aforementioned changes should minimize (possible to zero) the chances of a SEGV happening.

destroyed before TQApplication (or specifically before disconnect from

Before that the allocations of TQThreadStorage objects from the main
thread were never destroyed and memory associated with them were never
freed. The second one isn't a huge problem as at that point program is
terminating anyway (but it still makes valgrind complain). The first one
is the bigger issue as destructors might contain some essential external
cleanups like removing temporary files.
Also make `TQApplication::guiThread()` return `0` when the thread is
destroyed (may happen on the program exiting during destruction of
statics).

TQXIMInputContext::setHolderWidget() function may be (and actually is)
called more than once. This results in multiple instances of the same
object being added to ximContextList. But the destructor removes only
one instance, which effectively results in leak of several bytes
whenever a window is opened.

As for now here are two sets of inputmethod options:
- -enable-inputmethod/disable-inputmethod - which seems to supposed to
control whether build the 'inputmethod' module or not
- -inputmethod/-no-inputmethod - which seems to supposed to
enable/disable inputmethod support without changing the ABI.
Before the patch both -disable-inputmethod and -no-inputmethod were just
breaking the build: -no-inputmethod were disabling some code with
support for the module, but didn't disabled the module build itself nor
build of plugins. -disable-inputmethod were disabling build of plugins
and module, but didn't disabled code depending upon it.
It seems the inputmethod support were still WIP when the last release of
Qt3 came to be, hence the mess.
This patch fixes the build if both -disable-inputmethod AND
-no-inputmethod are supplied. Disabling only one is not enough due to
tqmake/configure have problems handling two different options of the
same name. Later the -inputmethod/-no-inputmethod should be probably
removed entirely.

This is the first part of the replacement process.
Usage of Q_WS_* has been replaced with the equivalent TQ_WS_*.
Definition of Q_WS_* has been mirrored into TQ_WS_* defines, to allow
TDE code to continue building till replacement is carried over to all
other modules.
Once that is completed, the original Q_WS_* defines will
be removed.
