Remove get_fd_list and get_vd_list from rtud's minipc since they're not used
anymore. Rtud's clients use now shmem to get the same information.
Remove helper functions from rtu_fd.c as not needed:
-rtu_fd_lookup_htab_entry
-rtu_vlan_entry_get
-vlan_entry_rd

Additionally following structures were removed as not needed:
-rtudexp_fd_entry_t
-rtudexp_fd_list_t
-rtudexp_vd_entry_t
-rtudexp_vd_list_t

Minipc call to get port state will not be used anymore, since HAL export port
state through shmem.
Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

Function hal_port_get_exported_state, fills structure hal_port_state with data
that are not available in SHM. It just assigns defines.
These defines are private to HAL, and assignment should be done in HAL.

Similar problem is for wrpc. There is a wrapper function that pretends to be
HAL. All HAL info should be filled in that function.

Fields added:
--uint32_t clock_period;
--uint32_t t2_phase_transition;
--uint32_t t4_phase_transition;

Additionally updated wrs_dump_shmem.c to dump new fields and the version number
of HAL SHM.

-DDEBUG in libwr forces LOG_DEBUG level in libwr/wrs-msg.c. This is
the desired behaviour, but we want it off by default now.

All other DEBUG symbols in Makefiles have no effect, so they are
removed to avoid tricking our developers in setting/unsetting them
and see no effect at all.

This was a build-time conditional. It is now a run-time conditional
using wrs-msg.  As a result, we have a verbose rtud. Fixed in next
commit.

typedefs are bad; and typedefs to void pointers more so (there is
no checking by the compiler any more).  Use an opaque structure instead.

There is no need to use packed structures unless they match hardware

for a reason.
