Move all explicit platform or architecture specific references
into a new platform.mk file that is defined for each platform.

This patch replaces the empty definition of display_boot_progress() in
bl2_main.c with a weak definition. The former allowed bl2 to use the
early_exceptions(). It is possible to do that with a simple weak
definition as well.

Ctags seem to have a problem with generating tags for assembler symbols
when a comment immediately follows an assembly label.
This patch inserts a single space character between the label
definition and the following comments to help ctags.
The patch is generated by the command:
git ls-files -- \*.S | xargs sed -i 's/^\([^:]\+\):;/\1: ;/1'

- This change is split into two separate patches in order to
simplify the history as interpreted by 'git'. The split is
between the move/rename and addition of new files.
- Remove dependency on toolchain C library headers and functions in
order to ensure behavioural compatibility between toolchains.
- Use FreeBSD as reference for C library implementation.
- Do not let GCC use default library include paths.
- Remove unused definitions in modified headers and implementations.
- Move C library files to 'lib/stdlib' and 'include/stdlib'.
- Break std.c functions out into separate files.

Platform setup code has to reserve some memory for storing the
memory layout information. It is populated in early platform setup
code.
blx_get_sec_mem_layout() functions used to return a copy of this
structure. This patch modifies blx_get_sec_mem_layout() functions
so that they now directly return a pointer to their memory layout
structure. It ensures that the memory layout returned by
blx_get_sec_mem_layout() is always up-to-date and also avoids a
useless copy of the meminfo structure.
Also rename blx_get_sec_mem_layout() to blx_plat_sec_mem_layout()
to make it clear those functions are platform specific.

This patch makes sure the C runtime environment is properly
initialised before executing any C code.
- Zero-initialise NOBITS sections (e.g. the bss section).
- Relocate BL1 data from ROM to RAM.

- Check at link-time that bootloader images will fit in memory
at run time and that they won't overlap each other.
- Remove text and rodata orphan sections.
- Define new linker symbols to remove the need for platform setup
code to know the order of sections.
- Reduce the size of the raw binary images by cutting some sections
out of the disk image and allocating them at load time, whenever
possible.
- Rework alignment constraints on sections.
- Remove unused linker symbols.
- Homogenize linker symbols names across all BLs.
- Add some comments in the linker scripts.

blx_plat_arch_setup() should only perform platform-specific
architectural setup, e.g. enabling the MMU. This patch moves
generic architectural setup code out of blx_plat_arch_setup().
