To make software license auditing simpler, use SPDX[0] license

The return value from the SYS_WRITE semihosting operation is 0 if
the call is successful or the number of bytes not written, if there
is an error. The implementation of the write function in the
semihosting driver treats the return value as the number of bytes
written, which is wrong. This patch fixes it.

Function declarations implicitly have external linkage so do not
need the extern keyword.

Update code base to remove variables from the .data section,
mainly by using const static data where possible and adding
the const specifier as required. Most changes are to the IO
subsystem, including the framework APIs. The FVP power
management code is also affected.
Delay initialization of the global static variable,
next_image_type in bl31_main.c, until it is realy needed.
Doing this moves the variable from the .data to the .bss
section.
Also review the IO interface for inconsistencies, using
uintptr_t where possible instead of void *. Remove the
io_handle and io_dev_handle typedefs, which were
unnecessary, replacing instances with uintptr_t.
Fixes ARM-software/tf-issues#107.

Reduce the number of header files included from other header
files as much as possible without splitting the files. Use forward
declarations where possible. This allows removal of some unnecessary
"#ifndef __ASSEMBLY__" statements.
Also, review the .c and .S files for which header files really need
including and reorder the #include statements alphabetically.
Fixes ARM-software/tf-issues#31

Add tag names to all unnamed structs in header files. This
allows forward declaration of structs, which is necessary to
reduce header file nesting (to be implemented in a subsequent
commit).
Also change the typedef names across the codebase to use the _t
suffix to be more conformant with the Linux coding style. The
coding style actually prefers us not to use typedefs at all but
this is considered a step too far for Trusted Firmware.
Also change the IO framework structs defintions to use typedef'd
structs to be consistent with the rest of the codebase.

Fixes issues #10:
https://github.com/ARM-software/tf-issues/issues/10
This patch changes all/most variables of type int to be size_t or long
to fix the sizing and alignment problems found when building with the
newer toolchains such as Linaro GCC 13.12 or later.

The modified implementation uses the IO abstraction rather than
making direct semi-hosting calls. The semi-hosting driver is now
registered for the FVP platform during initialisation of each boot
stage where it is used. Additionally, the FVP platform includes a
straightforward implementation of 'plat_get_image_source' which
provides a generic means for the 'load_image' function to determine
how to access the image data.

- 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.
