If you call lldpcli from a program, stdout will be fully buffered, and
we won't get back the result of "show neighbors" (nor anything else).
Expectedly, stderr messages are delivered immediately.

You can verify this by running "cat | lldpcli", give comamnds and
then exit with ctrl-D (EOF).

Add LDAP+kerberos support
This changes the used standard C library (due to lack of /etc/nsswitch.conf support)
and uses openssh instead of dropbear (due to lack of LDAP/kerberos
support in the dropbear)

Since nss-pam-ldapd 0.8.4 the uniqueMember attribute was replaced by
using the member attribute by default. This means that you should use

map group member sAMAccountName

dropbear was replaced, because it does not support correctly LDAP+kerberos.

It was almost working. With LDAP+Kerberos over PAM dropbear was prompting once
more for a password when the correct was given.

1/ wr_date script:
- Started before PPSi
- Set number of NTP retries to 10 if GM otherwise 1. GM info is
extracted from dot-config
- Clock source is controlled directly with wr_date tool
- Can be started any time without any risk to set a wrong date (see
point 2)
2/ wr_date
- 'set host' parameters take into account the time mode ( FR: set
sec+ns, BC: time cannot be set, GM: set seconds only+wait to be in a
middle of a second)
- function substrat_substrat() moved to time_lib.h. Also used by wr_mon
3/ wr_mon
- Print TAI-UTC
- Update Timing Mode & PLL locking state displayed values

- Check if we are in GM mode, if yes :
    - wait GM to be locked
    - Disable WR as kernel clock source
    - Increase retries for NTP
- Retries x time NTP until setting host time:
    - Set date from host to WR
    - Enable (back) WR as kernel clock source

By doing this we force to read again the FPGA register inside the loop
     and the compiler can not skip this loop thinking he is reading the
same value (that was not modified by him).

Fix TAI offset into kernel was done withing get function but this has
been removed in commit #91f4c8d. As it is still needed by slave, we
force its use using -n option. This will only fix tai offset into kernel
without applying ToD to WR/FPGA time.

Conflicts:
	userspace/tools/wr_date.c

Use gmtime instead of localtime (TAI should never used localtime)
Add verbose option to also display linux time
