gnc_start_of_week
* ICU has a mature C++ api, so prefer that one in our C++ code
* Use PERR instead of fprintf for consistent reporting
* Add the ICU specific linker flags to the test case
This function complements gnc_time64_get_day_begin/end. There was
time64CanonicalDayTime but this returned noon of the given day, where we
want 10:59am in most cases. I haven't changed time64CanonicalDayTime
directly as that may break assumptions in other parts of the code.
Instead I have created a new function that can be gradually introduced.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
