Commit 73c20eea

 removed that symbol
from fel.c - this adds it back (in the Makefile) to address #22.

Caveat: This probably requires you to use "make OS=NetBSD". I have
currently no way of testing it; we're only checking Linux and OSX
builds.

Add continuous integration support (Travis CI), fix Mac OS X build

The nand-part.c code tries to re-read the partition tables
by issuing an ioctl(fd, BLKRRPART, NULL). This isn't available
on non-Linux platforms, e.g. Mac OS X.

Add preprocessor conditionals to prevent this from breaking
the build.

For Linux, this requires additional #defines, see
https://gist.github.com/panzi/6856583#gistcomment-1656524



Placing those #defines into portable_endian.h would mean we
depend on the specific order of #includes (whatever pulls
in endian.h first, including other system includes). Avoid
this by using symbols provided "globally" via the Makefile.

Also nuke the _NETBSD_SOURCE definition in fel.c

Our previous include file only supplied a very limited set of
wrapper redefinitions for platforms that define __APPLE__ (i.e.
Mac OS). In particular, some needed big endian conversions were
missing, causing "symbol(s) not found" errors when linking.

Instead of patching the existing file, let's do away with it
completely and replace it by something more sophisticated.
The portable_endian.h used is in the public domain, and was
taken from https://gist.github.com/panzi/6856583

Commit 472ac475

 introduced
a possible regression by relying on the availability of
libusb_strerror(). There are libusb versions out there _not_
offering this function, which breaks compilation.

Introducing a separate helper function allows us to work around
this, refactor existing code and have more streamlined error
reporting - avoiding the message string retrieval where needed.
The usb_error() function can also optionally abort execution
with a given exit code.

When declaring 'signed' values for section count and version
information in the script_bin_head structure, testing them to be
below certain thresholds (SCRIPT_BIN_*_LIMIT) is insufficient;
as 'negative' values like in "fexc-bin: script.bin: version:
-404840454.-1074397186.-1073906177" would still pass.

Fix this by making these member fields unsigned.

The patch was originally inspired by
https://github.com/NextThingCo/sunxi-tools/commit/16386a7
and
https://github.com/NextThingCo/sunxi-tools/commit/47bafaf



It introduces a "--dev" (-d) option to specify the desired FEL
device. This is useful if multiple target devices are connected
to the same host.

Commit d99d59c0

 introduces a bug when the "spl" command is used with a
file that contains a U-Boot binary. "spl" will now try to execute it,
while it's not supposed to. (The command should only start the SPL.)

This patch brings back the `uboot_autostart` flag, which is meant to
remain `false` for the "spl" command, and gets set by "uboot" only.

This patch adds an "echo-gauge" command that is intended for use with
sunxi-fel's output piped into the dialog utility. "echo-gauge" will
output its string argument in a way that updates (i.e. overwrites)
the prompt text that dialog displays, so it's possible to change that
inbetween file transfers from sunxi-fel.

Example:
	sunxi-fel uboot ${UBOOT} \
		echo-gauge "Uploading kernel (1/2)" \
		write-with-gauge 0x42000000 ${KERNEL} \
		write 0x43100000 ${SCRIPT} \
		echo-gauge "Uploading rootfs (2/2)" \
		write-with-gauge 0x44000000 ${ROOTFS} \
		| dialog --gauge "" 6 70

This patch adds some additional commands, and implements corresponding
progress callbacks that produce output for the 'dialog' utility:
http://invisible-island.net/dialog/dialog.html



The simple "*-with-gauge" just emits percentage numbers, line by line,
while "*-with-xgauge" outputs extended information to update the
dialog prompt. Both are meant for directly piping the output:
sunxi-fel write-with-gauge <...> | dialog --gauge "FEL upload" 6 70

The two new commands both imply that a (simple) progress bar
display is requested. "multi[write]" allows to upload a group
of files with a single command, resulting in their transfer
showing a common, 'overall' progress status.

This patch moves some code out of the "write" handler, with the intention
to reuse it later for similar commands.

At the same time, it also discards the previous transfer rate output when
using "-v", as that has become redundant with the 'progress bar' display
available by "-p".

The script_extractor tool before this commit used to take a size argument
on the cmdline, but the passed in size was only used in some places not
in others. Leading to a segfault if the passed in argument was not
exactly the same as SCRIPT_SIZE.

This commit drops the argument, so that script_extractor will just
work.
