Jani Heikkinen 83a5694dc2 Update copyright headers
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Outdated header.LGPL removed (use header.LGPL21 instead)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

Robin Burchell 442eee3cda QStack: Add a simple benchmark.
This covers the only real additions over QVector: push and pop. Really, there
isn't too much specific to benchmark here, but we're interested in one specific
case: that of pushing and popping a single item repeatedly.

With the current QVector behavior, this causes constant deallocation, which
makes it morbidly slow. This behavior will be reviewed in a subsequent commit.

Results (not that anyone really cares) for me:
    PASS   : tst_QStack::qstack_push()
    RESULT : tst_QStack::qstack_push():
         1.9 msecs per iteration (total: 61, iterations: 32)
    PASS   : tst_QStack::qstack_pop()
    RESULT : tst_QStack::qstack_pop():
         8.2 msecs per iteration (total: 66, iterations: 8)
    PASS   : tst_QStack::qstack_pushpopone()
    RESULT : tst_QStack::qstack_pushpopone():
         80 msecs per iteration (total: 80, iterations: 1)
