Apply TBBR naming convention to the fip_create options

The fip_create tool specifies images in the command line using the
ARM TF naming convention (--bl2, --bl31, etc), while the cert_create
tool uses the TBBR convention (--tb-fw, --soc-fw, etc). This double
convention is confusing and should be aligned.

This patch updates the fip_create command line options to follow the
TBBR naming convention. Usage examples in the User Guide have been
also updated.

NOTE: users that build the FIP by calling the fip_create tool directly
from the command line must update the command line options in their
scripts. Users that build the FIP by invoking the main ARM TF Makefile
should not notice any difference.

Clarify "Getting the TF source code" in user guide

Remove the following redundant sentence from the user guide, which
implies the user should use the TF version from the Linaro release,
which was not the intention:

"However, the rest of this document assumes that you got the
Trusted Firmware as part of the Linaro release."

Also, tidied up the grammar in this section.

Introduce the ARM TF reset design document

This patch introduces a new document presenting the ARM Trusted
Firmware Reset Design. It shows the reset code flow, lists the
different build options that affect it, in which case to use them
and what their exact effect is.

The section about using BL31 entrypoint as the reset address has
been moved from the general firmware design document to this one.
It's also been improved to explain why the FVP port supports the
RESET_TO_BL31 configuration, even though the reset vector address
can't be programmed dynamically.

This document includes some images, which have been generated using
Dia version 0.97.2. This tool can be obtained from:
https://wiki.gnome.org/Apps/Dia/Download
This patch provides:
- the image files describing the different reset flow diagrams;
- the source '.dia' file;
- a script automating the generation of the images from the '.dia'
file.
Note that the 2 latter files are not actually needed for the document
and are provided for convenience only, in case the reset images need
to be modified.

Documentation updates for the new GIC drivers

This patch updates the relevant documentation in ARM Trusted Firmware
for the new GIC drivers. The user-guide.md and porting-guide.md have been
updated as follows:

* The build option to compile Trusted Firmware with different GIC drivers
for FVP has been explained in the user-guide.md.

* The implementation details of interrupt management framework porting
APIs for GICv3 have been added in porting-guide.md.

* The Linaro tracking kernel release does not work OOB in GICv3 mode.
The instructions for changing UEFI configuration in order to run with
the new GICv3 driver in ARM TF have been added to user-guide.md.

The interrupt-framework-design.md has been updated as follows:

* Describes support for registering and handling interrupts targeted to EL3
e.g. Group 0 interrupts in GICv3.

* Describes the build option `TSP_NS_INTR_ASYNC_PREEMPT` in detail.

* Describes preemption of TSP in S-EL1 by non secure interrupts and
also possibly by higher priority EL3 interrupts.

* Describes the normal world sequence for issuing `standard` SMC calls.

* Modifies the document to correspond to the current state of interrupt
handling in TSPD and TSP.

* Modifies the various functions names in the document to reflect
the current names used in code.

Replace all SCP FW (BL0, BL3-0) references

This patch replaces all references to the SCP Firmware (BL0, BL30,
BL3-0, bl30) with the image terminology detailed in the TF wiki
(https://github.com/ARM-software/arm-trusted-firmware/wiki):

BL0 --> SCP_BL1
BL30, BL3-0 --> SCP_BL2
bl30 --> scp_bl2

This change affects code, documentation, build system, tools and
platform ports that load SCP firmware. ARM plaforms have been
updated to the new porting API.

IMPORTANT: build option to specify the SCP FW image has changed:

BL30 --> SCP_BL2

IMPORTANT: This patch breaks compatibility for platforms that use BL2
to load SCP firmware. Affected platforms must be updated as follows:

BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID
BL30_BASE --> SCP_BL2_BASE
bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo()

Move up to mbed TLS 2.x

The mbed TLS library has introduced some changes in the API from
the 1.3.x to the 2.x releases. Using the 2.x releases requires
some changes to the crypto and transport modules.

This patch updates both modules to the mbed TLS 2.x API.

All references to the mbed TLS library in the code or documentation
have been updated to 'mbed TLS'. Old references to PolarSSL have
been updated to 'mbed TLS'.

User guide updated to use mbed TLS 2.2.0.

NOTE: moving up to mbed TLS 2.x from 1.3.x is not backward compatible.
Applying this patch will require an mbed TLS 2.x release to be used.
Also note that the mbed TLS license changed to Apache version 2.0.

Move up dependency versions in user guide

Move up the version numbers in the user guide of:

* DS-5 (to v5.22)
* Base FVP (to 7.0)
* Foundation FVP (to 9.4)
* Linaro release (to 15.10)

Note that, starting from Linaro release 15.10, the related release
instructions have migrated from http://releases.linaro.org to the
ARM Connected Community website. The URLs in the User Guide have
been updated accordingly.

The 'libssl-dev' package has been removed from the list of
prerequisite tools, as it is already referenced on the ARM Connected
Community page. Also, the 'device-tree-compiler' package has been
marked as an optional dependency, since the Trusted Firmware
repository provides the prebuilt DTB files. Hence, this tool is
needed only when the user wants to rebuild the DTS files.

De-feature PL011 UART driver to match generic UART spec

The Server Base System Architecture document (ARM-DEN-0029)
specifies a generic UART device. The programmer's view of this
generic UART is a subset of the ARM PL011 UART. However, the
current PL011 driver in Trusted Firmware uses some features
that are outside the generic UART specification.

This patch modifies the PL011 driver to exclude features outside
the SBSA generic UART specification by setting the boolean build
option 'PL011_GENERIC_UART=1'. Default value is 0 (use full
PL011 features).

User guide updated.
