The ASAN talk at QtCon was pointing out a out of
bound read in a vector.
Let's try to do something about it.
If the lazy initialization of compose table fails,
the first character handling still tries to actually
access it. Later characters are properly handled
in the caller.

From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

The extra length has been used for a sentinel null value.
By checking the index before indexing into the array, that
extra element can be dropped.

Avoid parsing the composition tables on application startup. Instead let's
do that on-demand the first time a composition key is pressed.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

Optimize the parser of the X11 compose tables. Parsing these was
responsible for over 90% of the startup time in Qt 5.1.

When switching from Xlib to xcb platform plugin it was agreed that
XIM is deprecated. Users should be using QT_IM_MODULE to load input context
plugin for a more advance input method framework support.
The proposed solution is to parse the compose file directly from Qt. This
approach removes the overhead of communication protocols used in Xlib and/or IBUS.
TableGenerator class follows [1].
The compose file is searched for in the following order:
1) If the environment variable $XCOMPOSEFILE is set,
its value is used as the name of the Compose file.
2) If the user’s home directory has a file named
.XCompose, it is used as the Compose file.
3) The system provided compose file is used by mapping the
locale to a compose file from the list in
/usr/share/X11/locale/compose.dir.
Regarding step 3 - TableGenerator searches in hard-coded locations for
system-provided compose files. Here I have introcuded a new environment
variable QTCOMPOSE which can be used to prepend an extra location
to be searched.
