Upgrade the zlib source files to the ones present in the version 1.2.13
of zlib [1]. Since 1.2.11 the use of Arm crc32 instructions has been
introduced so update the files to make use of this.

Added software CRC32 support in case platform doesn't support
hardware CRC32.
Platform must include necessary Zlib source files for compilation
to use software CRC32 implementation.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

When enabling VERBOSE() traces, the zlib library fails to compile
because of an incompatible format specifier string. Fix that.

This commit adds some more files to use zlib from TF.
To use zlib, ->zalloc and ->zfree hooks are needed. The implementation
depends on the system. For user-space, the libc provides malloc() and
friends. Unfortunately, ARM Trusted Firmware does not provide malloc()
or any concept of dynamic memory allocation.
I implemented very simple calloc() and free() for this. Stupidly,
zfree() never frees memory, but it works enough for this.
The purpose of using zlib is to implement gunzip() - this function
takes compressed data from in_buf, then dumps the decompressed data
to oub_buf. The work_buf is used for memory allocation during the
decompress. Upon exit, it updates in_buf and out_buf. If successful,
in_buf points to the end of input data, out_buf to the end of the
decompressed data.
To use this feature, you need to do:
- include lib/zlib/zlib.mk from your platform.mk
- add $(ZLIB_SOURCES) to your BL*_SOURCES

Import the following files from zlib 1.2.11:
adler32.c
crc32.c
crc32.h
inffast.c
inffast.h
inffixed.h
inflate.c
inflate.h
inftrees.c
inftrees.h
zconf.h
zlib.h
zutil.c
zutil.h
The original tarball is available from http://zlib.net/
The zlib is free software, distributed under the zlib license. The
license text is included in the "zlib.h" file. It should be compatible
with BSD-3-Clause.
The zlib license is included in the SPDX license list available at
https://spdx.org/licenses/, but I did not add the SPDX license tag to
the imported files above, to keep them as they are in the upstream
project. This seems the general policy for ARM Trusted Firmware, as
SPDX License Identifier was not added to files imported from FreeBSD.
