This patch introduces a configuration symbol RELEASE for managing debug/release
build in a similar way to how we manage PLATFORM.
Note:
1. 'make defconfig RELEASE=1' will still use the CONFIG_RELEASE defined in the
default configuration. The 'RELEASE=1' option has no effect in this case.
2. 'make RELEASE=1' is backward-compatible and enforces a release version to be
built.
v1 -> v2:
* Pass RELEASE instead of CONFIG_RELEASE to silentoldconfig.py to avoid
unintended overriding of the value.

Since .config has PLATFORM now, it is expected that the PLATFORM= command line
option is no longer necessary as long as a proper .config exists.
This patch implements this expectation. Now the platform to be selected is
determined by the following steps.
1. If PLATFORM= is provided on the command line, the specified value is
used.
2. If there is no PLATFORM= on the command line and PLATFORM is defined in
config.mk, its value is used.
3. If neither PLATFORM= on the command line nor config.mk is available, a
predefined default value is used.
v1 -> v2:
* 'make oldconfig' should not pass CONFIG_xxx to the script since config.mk
can be out-dated.
* Change the default value of PLATFORM to SBL for backward compatibility of
'make all'.

expanding FOO in a file path results the following (which is invalid):
SRC += a/b/${FOO}.c --> SRC += a/b/"a".c

This patch adds a new target to build the documentation
from the top-level directory. Here is how to use it (from
the top-level source directory):
$ make doc
Or
$ make O=build-test doc
To clean all documentation build artefacts, simply call
$ make clean
Or
$ make O=build-test clean
Calling 'make' with no arguments will *not* build the
documentation by default.

This patch renames $(O) used in the documentation Makefile

Makefile. This is required in order *not* to break setting a
