ltlcross: replace %H,%T,%N by %O

Browse source 
Also get rid of the lbt_parser, and fix the LBT support of the HOA
parser.

* doc/org/ltlcross.org, doc/org/ltldo.org: Update.
* src/bin/common_trans.cc, src/bin/common_trans.hh: Add support for
%O, and keep %T,%N,%H as hidden aliases without disabling them.
* src/bin/ltlcross.cc, src/bin/ltldo.cc, src/tgbatest/ltl2tgba.cc:
Call hoa_parse instead of lbt_parse.
* src/hoaparse/hoaparse.yy: Improve error reporting from LBT.
* src/hoaparse/hoascan.ll: Fix typos preventing parsing of
LBT files with more than 10 states.
* src/tgbaalgos/lbtt.cc, src/tgbaalgos/lbtt.hh: Delete the lbt
parser.
* src/tgbatest/lbttparse.test: Adjust the expected error message.
* NEWS: Update.
