[Development] important: upcoming rename of _qpa.h to _p.h

[Girish Ramakrishnan]

Hi,
If you are a module maintainer, please check the patches below and
provide comments.

As per the previous discuss, I renamed all the _qpa.h to _p.h with a
couple of helper scripts  - one script renamed the files and another
fixed the includes. Practically all the hardwork was done by my trusty
i-7 :) I lost one the renaming scripts because of a git clean -dxf.
The other scripts is below [2]. The scripts are not important since I
have done most of the work already.

There's no need to test anything now, let's just wait for api_changes
to merge. Once api_changes is merged, I will rebase and fix any
conflicts in the patches below. And then each module owner has to
check if the below compiles well.

The main reason for this mail is the size of the change itself and if
there is any concern now is a good time to voice it. The patch is
~13000 lines: (tests, examples all compile and work)
(qtbase) https://codereview.qt-project.org/#change,23443
(qtdeclarative) https://codereview.qt-project.org/#change,23444
(qtsystem - not compiled) https://codereview.qt-project.org/#change,23445
(qtwayland - not uncompiled) https://codereview.qt-project.org/23446

QtWebKit needs to have a small fix too.
