Dynamic cfg: Update the tools ...

This patch updates the `fiptool` and `cert_create` for the
`hw_config` and `tb_fw_config` dynamic configuration files.
The necessary UUIDs and OIDs are assigned to these files and
the `cert_create` is updated to generate appropriate hashes
and include them in the "Trusted Boot FW Certificate". The
`fiptool` is updated to allow the configs to be specified
via cmdline and included in the generated FIP.

cert_tool: Support for legacy RSA PKCS#1 v1.5 ...

This patch enables choice of RSA version at run time to be used for
generating signatures by the cert_tool. The RSA PSS as defined in
PKCS#1 v2.1 becomes the default version and this patch enables to specify
the RSA PKCS#1 v1.5 algorithm to `cert_create` through the command line
-a option. Also, the build option `KEY_ALG` can be used to pass this
option from the build system. Please note that RSA PSS is mandated
by Trusted Board Boot requirements (TBBR) and legacy RSA support is
being added for compatibility reasons.

cert: move platform_oid.h to include/tools_share for all platforms ...

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).

For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd.  This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.

The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h

Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1.  USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.

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

cert_create: fix memory leak bug caused by key container overwrite ...

In the current code, both key_load() and key_create() call key_new()
to allocate a key container (and they do not free it even if they
fail).  If a specific key is not given by the command option,
key_load() fails, then key_create() is called.  At this point, the
key container that has been allocated in key_load() is still alive,
and it is overwritten by a new key container created by key_create().

Move the key_new() call to the main() function to make sure it is
called just once for each descriptor.

While we are here, let's fix one more bug; the error handling code
  ERROR("Malloc error while loading '%s'\n", keys[i].fn);
is wrong because keys[i].fn is NULL pointer unless a specific key is
given by the command option.  This code could be run in either case.

Fix `cert_create` tool for Segmentation fault ...

With the introduction of commit `96103d5a`, the Certificate
Generation tool is not able to generate FWU certificate and
while doing so it does segmentation fault.

This happens because it is now required to pass non-volatile
counter values to the `cert_create` tool from the command line
for creating the trusted firmware certificates.

But in case of creating FWU certificate these counter values are not
being passed to the tool and as a consequence the `cert_create` tool
try to use the NULL argument and errors out with Segmentation fault.

This patch fixes this issue by providing a check before using the
command line argument passed in the case of `EXT_TYPE_NVCOUNTER`
certificate extension.

Make improvements for host environment portability

Make:Allow for extension in tool names. ...

In some build environments executable programs have a specific file
extension.  The value of BIN_EXT is appended to the relevant tool file
names to allow for this.
The value of BIN_EXT is set, where appropriate, by the build environment
specific make helper (to .exe for Windows build environments).

.gitignore is updated to hide the new (.exe) files.

Make:Use environment variables for OS detection. ...

Add make helper files to select the appropriate settings for the build
environment. Selection is made in make_helpers/build_env.mk, which
selects other files to include using generic build environment settings.
The Trusted Firmware Makefile and supporting tool Makefiles are updated
to include build_env.mk instead of unix.mk.

NOTE: This change does not fully enable builds in other build
      environments. It facilitates this without compromising the
      existing build environments.

like build environments by providing the following macro definitions:
  SHELL_COPY        cp -f
  SHELL_COPY_TREE   cp -rf
  SHELL_DELETE      rm -f
  SHELL_DELETE_ALL  rm -rf
  MAKE_PREREQ_DIR   mkdir -p  (As make target)

not possible to reimplement this as a make function. Avoiding invocation
of this on incompatible host platforms will be implemented separately.

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

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