Build system improvements

For now, this is for informational purposes (program version
output), but it might also serve as an anchor point for a
"bugfix" release after some changes made to the build system.

For Linux build testing, we want all targets compiled. To do so
without a cross-toolchain, simply use the host compiler for the
target tools. This can be achieved by setting CROSS_COMPILE to
an empty string.

OSX can't handle this: It neither supports "-static", nor would
it successfully compile meminfo.c. Thus we keep the default
"make", which should only build the 'tools' target.

On Linux we'll also test the install-* targets by requesting
installation to /tmp/sunxi-tools as a post-build step.

This appends sunxi-meminfo to the TARGET_TOOLS, and adds a new rule
to fix the compilation of sunxi-pio (by making it *cross-compile*
for the target).

Additionally adds a new build target "make install-misc".

For more details, see github issues #69 and #70.

Minor compilation fixes

(Changing to a proper struct initializer avoids a possible
compiler warning.)
Signed-off-by: Bernhard Nortmann <bernhard.nortmann@web.de>

Fixing the (currently erroneous) compilation of sunxi-pio will
cause "make target-tools" to require a suitable cross-compiler
installed. Otherwise "make target-tools" fails to build.
As that is part of our default target ("make all"), we might
possibly introduce a build breakage on quite a few systems.

Avoid this situation by redefining "make tools" as the default,
and change "make install" to "make install-tools", i.e. limit
the standard targets to those builds that only rely on the host
toolchain. From now, if you actually want to include the cross-
compiling steps, use "make all" or "make install-all" instead.

Also: Add the winsock2 library to LIBS for Windows. When not
linking against it, the usage of WS2 conversion functions from
portable_endian.h would cause unresolved symbols.
Signed-off-by: Bernhard Nortmann <bernhard.nortmann@web.de>

For Windows portable_endian.h relies on and includes <winsock2.h>.
Thus it needs to be requested first, otherwise other includes might
pull in <windows.h> and cause a preprocessor warning / compilation
failure (observed with MinGW).

By defining NO_MMAP it's now possible to avoid the usage of
mmap() and munmap(). This benefits platforms that don't support
these functions, e.g. Windows.

Add support for version information 

fel: Improve file_upload() when no progress callback is passed

This commit renames the function pointer of type progress_cb_t
for file_upload(). That might help to avoid potential confusion
with other routines that use a boolean "progress" parameter to
indicate whether progress information is desired (at all).
Signed-off-by: Bernhard Nortmann <bernhard.nortmann@web.de>

Until now, the function would always pass `true` as the "progress"
parameter to aw_write_buffer(). This has the potential drawback
of limiting the maximum USB transfer size.

By selectively passing `false` instead (with no progress function
active), we hint that aw_write_buffer() and subsequent routines
don't have to care about callbacks; so that usb_bulk_send() is
free to select a transfer size of AW_USB_MAX_BULK_SEND.

This way we don't have to introduce new options for retrieving
version info. For those programs that do not output their usage
by default (e.g. because they would process stdin), you may pass
a "-?" option to get help - and thus version information.

* fel: Add the ability to pass uEnv-style data via FEL

The corresponding format is recognized by having the environment
data (= text) start with a special "#=uEnv" marker. Upon transfer
of such a file, sunxi-fel will detect this condition, and set a
field in the SPL header accordingly - which in turn also requests
U-Boot to auto-import it (i.e. merge with the default environment).

(Note that this requires a U-Boot version that knows about the
new meaning of this field, namely v2016.09 or later. Older U-Boot
versions will fail to import the uEnv-style data.)

The Makefile will now use a script (autoversion.sh) to update
version.h, which in turn defines a VERSION string and gets
included from common.h.

The idea is that version.h normally receives a git-describe
based identifier that represents the current checkout. In
cases where git might not be available, e.g. for builds from
a tarball, the script will instead fall back to a predefined
version (that should reflect the most recent release tag).

Add a tool to generate raw NAND images

Generating raw NAND images is particularly useful for boot0 images
creation since the mainline driver is not supporting the funky layout
used by Allwinner's ROM code to load the boot0 binary from NAND.

This tools also allows one to generate raw images for 'normal' partitions
so that they can be flashed before soldering on the NAND on the board
(using a regular NAND programmer).

The tool takes care of generating ECC bytes and randomizing data as
expected by the NAND controller, and re-arranging the ECC/data sections
correctly.
