Refactor and bugfix the delay adding code for analog capture
There're two essential modifications in this change:
1. Fix timing for capture frequencies less than 200 kHz;
2. Sample ADC output after CLK is set low, as per the TLC5510
datasheet.
The second point is also important as the capture state sets CLK low,
so with the previous code there might have been a very short glitch on
this line during capture. Not confirmed by measurements, but it's
cleaner this way.

fx2lafw: clock CTL1 the same as CTL2
The LHT00SU1 has it's clock pins swapped compared to other hardware.
By duplicating the CTL2 pin both the socket and the adc will
have the same clock frequency.

Makefile.am: Hook up building of hantek-6022be.fw.
The FX2 firmware for the Hantek 6022BE USB-based oscilloscope uses most
of the existing fx2lafw build infrastructure and our existing fx2lib setup,
but requires slightly different sdcc linker settings due to different code
and XRAM sizes and locations, etc.

Add FX2 firmware for the Hantek 6022BE USB scope.
This firmware was originally created by Jochen Hoenicke in 05/2015
for the Hantek6022API github project by Robert Cope. Full credit for
the implementation of the firmware goes to Jochen Hoenicke, thanks!
Github project:
https://github.com/rpcope1/Hantek6022API
We're incorporating the firmware into the sigrok-firmware-fx2lafw
repo/tarball for convenience of sigrok users. E.g. so that they can
easily get it with the other fx2lafw firmware files from distro
packages, the build scripts in sigrok-util automatically build/install
it, the sigrok Windows installers automatically ship it, the sigrok
Android APKs automatically ship it, etc. etc.
The files we're integrating into fx2lafw from Hantek6022API are taken from
the PyHT6022/HantekFirmware/custom directory of that repo, using the state
as of 03/2016 (the files were last modified in 05/2015, though).

Add fx2lafw firmware for FX2 devices with sigrok VID/PID.
The two new firmware images fx2lafw-sigrok-fx2-{8,16}ch.fw can be used
on Cypress FX2 devices where one of the two official sigrok fx2lafw
USB VID/PID pairs is hardcoded in an external EEPROM.
The sigrok project owns USB product IDs allocated via the Openmoko project:
http://wiki.openmoko.org/wiki/USB_Product_IDs
The following two VID/PID pairs are available for devices that use
a Cypress FX2(LP) chip *directly* as 8-channel or 16-channel logic analyzer,
and use the respective USB-based protocol. They are *not* meant for
other devices which just happen to also have an FX2 (e.g. in addition to
an FPGA) and/or devices that use a different USB-based protocol.

Increase FX2LAFW_VERSION_MINOR to 1.
There have been changes since the last release, but they have been
compatible ones that don't require any host-side (libsigrok) changes,
thus only increase FX2LAFW_VERSION_MINOR (but not FX2LAFW_VERSION_MAJOR).

COPYING.LESSER: Replace LGPLv3 with LGPLv2.1.
The file incorrectly contained a copy of the LGPL, version 3. It should
have contained version 2.1 though, since that's the license of the

Support older Cypress FX2 (not FX2LP) too.
The Cypress FX2 chip is an older version of the FX2LP chip with a few
differences that might be relevant for fx2lafw, the major one being
that is has less internal SRAM.
We adapt the linking step to work for both FX2 and FX2LP, thus
keeping only one set of *.fw files for both chip versions.
Changes to the fx2lafw driver in libsigrok are not required.
Some logic analyzer devices such as older USBee SX versions or more recent
devices which use a "fake" FX2LP (which is actually an FX2) need this.

Use a standard autotools setup.
fx2lafw now uses a standard autoconf/automake based build and
configuration system like most other sigrok subprojects (instead of two
sets of custom, not very portable Makefiles).
$ ./configure && make && make install
It now supports all the usual things one expects, for example:
- The --prefix et. al. options to specify installation paths.
- Standard set of 'make' targets, e.g. 'install', 'uninstall',
'dist', etc.
- In-tree builds as well as out-of-tree builds.
- Works pretty much everywhere portably, regardless of 'make'
implementation (GNU Make or BSD make or...) and regardless of shell
(bash, sh, dash, ksh, csh, ...).
- The build output matches the usual 'silent rules' output of other
(sigrok / autotools) projects. Using 'make V=1' one can get the full
build output.

Use makebin if objcopy is not available.
Some systems might not have objcopy (e.g. on Mac OS it might not be
available per default). We use objcopy if it is found, otherwise we try
to use the 'makebin' utility (shipped with sdcc) instead.

Makefile: Add a 'distbin' target.
This creates a sigrok-firmware-fx2lafw-bin-x.y.z.tar.gz tarball which
only contains pre-built *.fw files (and some docs), but no source code

This tarball can be provided as a convenience download for users who do
not want to mess with building their own firmware files from source.
