0f702c6e70 Create local C library implementation (2/2)
- 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.

4a826ddad8 rework general purpose registers save and restore
The runtime exception handling assembler code used magic numbers for
saving and restoring the general purpose register context on stack
memory. The memory is interpreted as a 'gp_regs' structure and the
magic numbers are offsets to members of this structure. This patch
replaces the magic number offsets with constants. It also adds compile
time assertions to prevent an incorrect assembler view of this
structure.

65f546a14f Properly initialise the C runtime environment
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.

295538bc37 AArch64: Remove EL-agnostic TLB helper functions
Also, don't invalidate the TLBs in disable_mmu() function, it's better
to do it in enable_mmu() function just before actually enabling the
MMU.

3738274dc1 Unmask SError and Debug exceptions.
Any asynchronous exception caused by the firmware should be handled
in the firmware itself.  For this reason, unmask SError exceptions
(and Debug ones as well) on all boot paths.  Also route external
abort and SError interrupts to EL3, otherwise they will target EL1.
