Fix fiptool packaging issue on windows ...

Windows does not have a standard getopt implementation. To address
this an equivalent implementation has been provided in win_posix.c
However, the implementation has an issue with option processing as
described below.

Long option names may be abbreviated if the abbreviation is unique
or an exact match for some defined option.
Since some options can be substring of other options e.g. "scp-fw"
option is a substring of "scp-fwu-cfg", we need to identify if an
option is abbreviated and also check for uniqueness. Otherwise if
a user passes --scp-fw as an option, the "scp-fwu-cfg" option may
get selected, resulting in an incorrectly packaged FIP.

This issue has been be fixed by:
  - First searching for an exact match.
  - If exact match was not found search for a abbreviated match.
By doing this an incorrect option selection can be avoided.

plat: Fix build issue for qemu and rpi3 platforms ...

Coverity build periodically throws below errors(non-consistently)
for 'QEMU' and 'RPI3' platforms.

/bin/sh: 1: cannot create build/qemu/debug/rot_key.pem: Directory
nonexistent
plat/qemu/qemu/platform.mk:86: recipe for target 'build/qemu/debug/
rot_key.pem' failed
make: *** [build/qemu/debug/rot_key.pem] Error 2

/bin/sh: 1: cannot create /work/workspace/workspace/tf-coverity/build
/rpi3/debug/rot_key.pem: Directory nonexistent
plat/rpi/rpi3/platform.mk:214: recipe for target '/work/workspace/
workspace/tf-coverity/build/rpi3/debug/rot_key.pem' failed
make: *** [/work/workspace/workspace/tf-coverity/build/rpi3/debug/
rot_key.pem] Error 2

Issue seems to be occurred when 'ROT key' is generated before creating
the platform build folder(for e.g.build/qemu/debug).

Changes are made to fix this issue by adding orderly dependancy of
the platform folder for the 'ROT key' creation which ensures that
platform folder is created before generating 'ROT key'.

tools: Set the tool's default binary name ...

This patch: fafd3ec9c assumes that tools must build from
the main makefile folder.
This assumption leads to the error when somebody wants to
build a tool from the tool's folder.
Hence changes are done to provide the default binary name
in the tool's makefile.

libc: memset: improve performance by avoiding single byte writes ...

Currently our memset() implementation is safe, but slow. The main reason
for that seems to be the single byte writes that it issues, which can
show horrible performance, depending on the implementation of the
load/store subsystem.

Improve the algorithm by trying to issue 64-bit writes. As this only
works with aligned pointers, have a head and a tail section which
covers unaligned pointers, and leave the bulk of the work to the middle
section that does use 64-bit writes.

Put through some unit tests, which exercise all combinations of nasty
input parameters (pointers with various alignments, various odd and even
sizes, corner cases of content to write (-1, 256)).

psci: utility api to invoke stop for other cores ...

The API can be used to invoke a 'stop_func' callback for all
other cores from any initiating core. Optionally it can also
wait for other cores to power down. There may be various use
of such API by platform. Ex: Platform may use this to power
down all other cores from a crashed core.

The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3
memory system variant is used, there won't be any L3 cache,
snoop filter, and SCU logic present hence no system control register
will be present. Hence check SCU presence before accessing DSU register
for DSU_936184 errata.

arm_fpga: Add support to populate the CPU nodes in the DTB ...

At the moment BL31 dynamically discovers the CPU topology of an FPGA
system at runtime, but does not export it to the non-secure world.
Any BL33 user would typically looks at the devicetree to learn about
existing CPUs.

This patch exports a minimum /cpus node in a devicetree to satisfy
the binding. This means that no cpumaps or caches are described.
This could be added later if needed.

An existing /cpus node in the DT will make the code bail out with a
message.
