Revision 221

clcdrag is no longer used in LMDZ. Replaced by cdrag in LMDZ. In cdrag
in LMDZ, zxli is a symbolic constant, false. So removed case zxli true
in LMDZE.

read_sst is called zero (if no ocean point on the whole planet) time or
once per call of physiq. If mod(itap - 1, lmt_pas) == 0 then we have
advanced in time of lmt_pas and deja_lu is necessarily false.

qsat[sl] and dqsat[sl] were never called.

Added output of qsurf in histins, following LMDZ.

Last dummy argument dtime of phystokenc is always the same as first
dummy argument pdtphys, removed dtime.

Removed make rules for nag_xref95, since it does not exist any longer.
