fip: move headers shared between TF and fiptool to include/tools_share ...

Some header files need to be shared between TF and host programs.
For fiptool, two headers are copied to the tools/fiptool directory,
but it looks clumsy.

This commit introduces a new directory, include/tools_share, which
collects headers that should be shared between TF and host programs.

This will clarify the interface exposed to host tools.  We should
add new headers to this directory only when we really need to do so.

For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).

Build: fix assert_boolean implementation ...

The current assert_boolean does not work with variables assigned with
'=' flavor instead of ':='.

For example,

 FOO = $(BAR)
 BAR := 1

Here, $(value FOO) is evaluated to $(BAR), not 1.  This is not what
we expect.  While I am here, I simplified the implementation.

Break circular dependency in FVP and Nvidia header files

Simplify assert() to reduce memory usage ...

The behaviour of assert() now depends on the value of the new optional
platform define `PLAT_LOG_LEVEL_ASSERT`. This defaults to `LOG_LEVEL` if
not defined by the platform.

- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_VERBOSE`, it prints the file
  name, line and asserted expression.
- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_INFO`, it prints the file
  name and line.
- If not, it doesn't print anything.

Note the old behaviour was to print the function name whereas now it
prints the file name. This reduces memory usage because the file name is
shared between all assert calls in a given file. Also, the default
behaviour in debug builds is to no longer print the asserted expression,
greatly reducing the string usage.

For FVP debug builds this change saves approximately:

Migrate ARM platforms to use TF_MBEDTLS_KEY_ALG ...

A previous patch superseded the MBEDTLS_KEY_ALG. This patch updates

mbedtls: Complete namespace for TF specific macros ...

This patch renames MBEDTLS_KEY_ALG to TF_MBEDTLS_KEY_ALG. This
completes the migration of TF specific macros so that they do not
have the MBEDTLS_ suffix (see arm-trusted-firmware#874).

mbedtls: Namespace for TF specific macros ...

An earlier patch (arm-trusted-firmware#874) migrated MBEDTLS_ suffixed
macros to have a TBBR_ suffix to avoid any potential clash with future
mbedtls macros.

But on reflection the TBBR_ suffix could be confusing as the macros
are used to drive TF-specific configuration of mbedtls. As such
this patch migrates these macros from TBBR_suffix to TF_MBEDTLS_
suffix which more accurately conveys their use.

AEMv8-A Model release v8.4 has been made available and Trusted Firmware
has been tested against these versions as part of its CI system. This

Additionally, ARM FVPs FVP_Base_Cortex-A57x1-A53x1 and
FVP_Base_Cortex-A57x2-A53x4 are removed from the list of tested FVPs
as they are currently not being tested with the latest version of ARM
Trusted Firmware.

Also, documentation and links to Linaro pages have been updated to
reflect the changes in the ARM community document hosting.
