Dan Handley f0b489c1d2 Move stdlib header files to include/lib/stdlib
* Move stdlib header files from include/stdlib to include/lib/stdlib for
  consistency with other library headers.
* Fix checkpatch paths to continue excluding stdlib files.
* Create stdlib.mk to define the stdlib source files and include directories.
* Include stdlib.mk from the top level Makefile.
* Update stdlib header path in the fip_create Makefile.
* Update porting-guide.md with the new paths.

Antonio Nino Diaz 191a008865 Compile stdlib C files individually
All C files of stdlib were included into std.c, which was the file
that the Makefile actually compiled. This is a poor way of compiling
all the files and, while it may work fine most times, it's
discouraged.

In this particular case, each C file included its own headers, which
were later included into std.c. For example, this caused problems
because a duplicated typedef of u_short in both subr_prf.c and
types.h. While that may require an issue on its own, this kind of
problems are avoided if all C files are as independent as possible.

Juan Castillo e509d05728 stdlib: add missing features to build PolarSSL
This patch adds the missing features to the C library included
in the Trusted Firmware to build PolarSSL:

  - strcasecmp() function
  - exit() function
  - sscanf()* function
  - time.h header file (and its dependencies)

* NOTE: the sscanf() function is not a real implementation. It just
returns the number of expected arguments by counting the number of
'%' characters present in the formar string. This return value is
good enough for PolarSSL because during the certificate parsing
only the return value is checked. The certificate validity period
is ignored.

Dan Handley 6ad2e461f0 Rationalize console log output
Fix the following issues with the console log output:

* Make sure the welcome string is the first thing in the log output
(during normal boot).
* Prefix each message with the BL image name so it's clear which
BL the output is coming from.
* Ensure all output is wrapped in one of the log output macros so it can
be easily compiled out if necessary. Change some of the INFO() messages
to VERBOSE(), especially in the TSP.
* Create some extra NOTICE() and INFO() messages during cold boot.
* Remove all usage of \r in log output.

Soby Mathew b79af93445 Implement a leaner printf for Trusted Firmware
This patch implements a "tf_printf" which supports only the commonly
used format specifiers in Trusted Firmware, which uses a lot less
stack space than the stdlib printf function.

James Morrissey f2f9bb5e71 Add IO abstraction framework
This is intended primarily for use as a storage abstraction.
It allows operations such as image-loading to be implemented
in a platform-independent fashion.  Each platform registers
a set of IO drivers during initialisation.  The platform must
also provide a function that will return a device and a specifier
that can be used to access specified content.

Clients of the API will primarily use device and entity handles.
The term "entity" is deliberately vague, to allow for different
representations of content accessed using different types of
specifier, but will often be interpreted as a "file" where the
specifier will normally be its path.

This commit builds, but is intended to be paired with a sample
implementation of "load_image" using a semi-hosting driver on FVP.

Jon Medhurst c3810c83aa Fix memmove and memcpy
memmove needs to allow for overlapping memory regions and, together
with memcpy, should return the input destination pointer, not the
address after the end of the copied data.

Harry Liebel 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.
