The current code assumed that READ/WRITE would produce atomic read/writes for
8/16/32-bit words, which in turned put assumption on the memcpy function.
Since some memcpy implementation do not always guarantee such strong assumption,
introduce two new operation READ/WRITE_ATOMIC which provide the necessary
tools to do correct read and write to register in a single memory access.

Because Qt doesn't support QObject multiple inherance, it is a bit tricky
to have a base class which interact with the UI. The register tab name
now display:
- file dump name (for dumps)
- hwstub device path (for hwstub)
And the register editor display the filename

Qeditor has been improved in many ways:
- it can now dump all registers, just like the lua DUMPER.dump_all() command
- several crash were fixed
- when connected to a hwstub command, one can correctly edit individual fields
- the code was simplified in several places

The graphical editor can now display and editor description files.
The library has been improved to provide more useful function.
The XML format has been slightly changed: only one soc is allowed per file
(this is was already de facto the case since <soc> was the root tag).
Also introduce a DTD to validate the files.

The UI now has a "read-only" check box to prevent accidently changes: once
unchecked, the UI can do write to register (only full register writes are
supported for now). If the register supports it, the UI provides SCT writes
as well. The display register panel was moved to its own class to cleanup
things a bit.

The code was a mess with respect to soc handling: some code just plain copied
the SoC descriptor which are big objects, some was using indexes. The new soc
factor out everything in a few classes which hide these ugly details so that
descriptors are never copied.

A SoC descriptor is not a small object: it can be as large as ~100KiB so
it's better to avoid copying things over.

This commit add the very handy feature of being able to read registers
directly from a device using hwstub. This is mostly trivial using the hwstub
library and the biggest change here is actually:
- being able to read registers by name and/or addresses
- being able to enumerate devives
The UI code currently doesn't handle hotplug but the backend does so it should
be trivial to add in the future. It also opens up the possibility the write
registers from hwstub or save the register values to a file.
Since it relies on both hwstub and libusb, a switch has been introduced in
qmake to disable it (use -config nohwstub).

This tool allows one to explore any register map. Register dumps
(like produced by hwstub tools) can be loaded and decoded by the
tool. Finally some analysers are provided for specific soc analysis
like clock tree and emi on imx233 for example.
