Replace fip_create with fiptool

fiptool provides a more consistent and intuitive interface compared to
the fip_create program. It serves as a better base to build on more
features in the future.

fiptool supports various subcommands. Below are the currently
supported subcommands:

1) info - List the images contained in a FIP file.
2) create - Create a new FIP file with the given images.
3) update - Update an existing FIP with the given images.
4) unpack - Extract a selected set or all the images from a FIP file.
5) remove - Remove images from a FIP file. This is a new command that
was not present in fip_create.

To create a new FIP file, replace "fip_create" with "fiptool create".

To update a FIP file, replace "fip_create" with "fiptool update".

To dump the contents of a FIP file, replace "fip_create --dump" with
"fiptool info".

A compatibility script that emulates the basic functionality of
fip_create is provided. Existing scripts might or might not work with
the compatibility script. Users are strongly encouraged to migrate to
fiptool.

Give user's compiler flags precedence over default ones

The user can provide additional CFLAGS to use when building TF.
However, these custom CFLAGS are currently prepended to the
standard CFLAGS that are hardcoded in the TF build system. This
is an issue because when providing conflicting compiler flags
(e.g. different optimisations levels like -O1 and -O0), the last
one on the command line usually takes precedence. This means that
the user flags get overriden.

To address this problem, this patch separates the TF CFLAGS from
the user CFLAGS. The former are now stored in the TF_CFLAGS make
variable, whereas the CFLAGS make variable is untouched and reserved
for the user. The order of the 2 sets of flags is enforced when
invoking the compiler.

Make:Improve version string generation portability

To get round problems encountered when building in a DOS build
environment the generation of the .o file containing build identifier
strings is modified.
The problems encounterred were:
1. DOS echo doesn't strip ' characters from the output text.
2. git is not available from CMD.EXE so the BUILD_STRING value needs
some other origin.

A BUILD_STRING value of "development build" is used for now.

MAKE_BUILD_STRINGS is used to customise build string generation in a DOS
environment. This variable is not defined in the UNIX build environment
make file helper, and so the existing build string generation behaviour
is retained in these build environments.

NOTE: This commit completes a cumulative series aimed at improving
build portability across development environments.
This enables the build to run on several new build environments,
if the relevant tools are available.
At this point the build is tested on Windows 7 Enterprise SP1,
using CMD.EXE, Cygwin and Msys (MinGW),as well as a native
Linux envionment". The Windows platform builds used
aarch64-none-elf-gcc.exe 4.9.1. CMD.EXE and Msys used Gnu
Make 3.81, cygwin used Gnu Make 4.1.

CAVEAT: The cert_create tool build is not tested on the Windows
platforms (openssl-for-windows has a GPL license).

Make:Improve directory generation portability.

Because of command differences in some build environments the "inline"
method of generating the build directory structure is not portable.
(e.g. in DOS environments the mkdir shell command fails if a directory
already exists, whereas in UNIX environments it succeeds.)

To improve portability we generate the directories needed using make,
but use the "order-only prerequisites" feature of make to prevent writes
of files into the directories generating re-builds, as suggested in the
GNU make Manual (Version 4.1 September 2014).

Note that the setting of BUILD_STRING still uses $(shell ) since it's
not possible to reimplement this as a make function. Avoiding invocation
of this on incompatible host platforms will be implemented separately.

The counter values can be specified in the command line.

The following default counter values are specified in the build
system:

* Trusted FW Non-Volatile counter = 0
* Non-Trusted FW Non-Volatile counter = 0

These values can be overridden by the platform at build time.

Apply TBBR naming convention to the fip_create options

The fip_create tool specifies images in the command line using the

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.

which includes above mentioned FWU images in the make files.

The new target of `fwu_fip` and its dependencies are included for
compilation only when `TRUSTED_BOARD_BOOT` is defined.

Fix build error when `BL32` is not defined

If an SPD wants to use a prebuilt binary as BL32 image (for example,
the OPTEE Dispatcher), it must point the `BL32` variable to the
image file. This dependency should apply only to the `fip` target.
However, it also applies to the `all` target at the moment. If the
user tries to build all individual TF images using `make all`
without setting BL32, the build fails. The following command will
throw the error:

make CROSS_COMPILE=aarch64-linux-gnu- SPD=opteed all
...
...
aarch64-linux-gnu-gcc: fatal error: no input files
compilation terminated.
make: *** [build/fvp/release/bl32/bl32.ld] Error 1

The reason is that the build system checks if BL32 is defined, and
if it is not, it will try to build BL32 from source. If the SPD
makefile does not provide support for that (as is the case of the
OPTEE Dispatcher, since OPTEE is provided as an external binary),
the build will fail.

This patch fixes the issue by checking if `BL32_SOURCES` has been
defined by the SPD before attempting to build BL32 from source.
If neither `BL32` nor `BL32_SOURCES` is defined when building the
FIP, a warning message will be printed and the process aborted.

Rework Makefile

This patch is a complete rework of the main Makefile. Functionality
remains the same but the code has been reorganized in sections in
order to improve readability and facilitate adding future extensions.

A new file 'build_macros.mk' has been created and will contain common
definitions (variables, macros, etc) that may be used from the main
Makefile and other platform specific makefiles.

A new macro 'FIP_ADD_IMG' has been introduced and it will allow the
platform to specify binary images and the necessary checks for a
successful build. Platforms that require a BL30 image no longer need
to specify the NEED_BL30 option. The main Makefile is now completely
unaware of additional images not built as part of Trusted Firmware,
like BL30. It is the platform responsibility to specify images using
the macro 'FIP_ADD_IMG'. Juno uses this macro to include the BL30
image in the build.

BL33 image is specified in the main Makefile to preserve backward
compatibility with the NEED_BL33 option. Otherwise, platform ports
that rely on the definition of NEED_BL33 might break.

All Trusted Board Boot related definitions have been moved to a
separate file 'tbbr_tools.mk'. The main Makefile will include this
file unless the platform indicates otherwise by setting the variable
'INCLUDE_TBBR_MK := 0' in the corresponding platform.mk file. This
will keep backward compatibility but ideally each platform should
include the corresponding TBB .mk file in platform.mk.
