The should pick other repositories from ../ only if both use and them
are submodules of ../ .

Only checking that ../zio is a directory is not enough, because it
can be a separate clone (old version, for example) or worse an
intermediate directory that doesn't host headers.

A user reported painful build errors for this reason.

This directly affects tools/fmc-fdelay-status, although the tool is
not changed.

TDC user offset should be applied to all timestamps. The code, however,
didn't do that properly, and fast_tdc mode was missing it.

Now user_offset is applied where the hardware offset is, like it should
have since time zero.

This should have no effect, as user_offset is an option nobody used
so far, as far as we know.

This should in a way fix the missing error checks in parse_time,
without forcing us to rewrite parsing with more stringent checks.

Times are reported before activating rather than after each parse
action, so the user can see what 1mhz or pps turn out to be, as
well as the default values.

Additionally, document the effect of delay-offset calibration parameter
in the read-back of values.

The header was a quick hack. This doesn't change anything in external
behaviour, but makes the inline functions into real function in
a library-like header linkerd in by all tools.

Reason: useful when debugging White Rabbit synchronized cards, which should be in sync with
better than 1ns accuracy. Also grouped decimal digits to improve readability.

- fix termination status printing (was showing null)
- error handling when setting termination

- more accurate error/status reporting in wr_mode/query_wr_mode
- prevent changing the board time when WR is on

- 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.
