- added gateware_install target, which automatically downloads and installs the FPGA gatewares
- improved submodule support. Now it looks for dependent submodules in the user-supplied path,
in the parent directory (a "super-module" repo) and if still not found, checks out local submodule copy.

This completely removes the "bugs" section, since no known bugs
remain.  The buffering problem on iput has long been solved, I just
forgot to check the complete manual until now.

- API changes for the latest driver (retreiving output configuration)
- updated info on gateware installation
- dropped 2.6.24 support
- consistency fixes (Time-stamps -> timestamps, etc.)
- moved raw I/O info into an appendix for developers.

The official release bitstreams are available at the Fine Delay
project website, along with release info and changelog.

This tool is deprecated, please use lib/ and tools/ tools instead.

To get the output configuration, a simple readback of the
sysfs start/end/delta parameters is not enough, because
start and end are affected by delay-offset and the tdc
offset. This patch addresses the problem in an incomplete
manner

The usual boring stuff to shut up the compiler warnings like
  fdelay-read.c:57: warning: format ‘%lli’ expects type ‘long long int’,
  but argument 3 has type ‘uint64_t’

We need to know the programmed delay, hence this extends the API
of the library to recover it in ps units. The ensuing arithmetic
is also added

A channel start, end and delta time registers are exported
read-only through sysfs to allow easy readback of the configured
values.

Now we can read back the programmed values of output registers,
so we allow its readout from user space

This patch unifies VIC interrupt handling by removing VIC support code from the driver
and using the one provided by the carrier. Since the SVEC now supports IRQs too, both
carriers can benefit from interrupts.
