Mark public symbols with SPOT_API.
Also accept guards of the form (a) || !(b) or (a) && !(b).
* src/neverparse/neverclaimscan.ll: Adjust.
* src/tgbatest/neverclaimread.test: Add a test case.
These translator may output guards such as (a) || (b), but with the
changes in Spot 1.1.3 it would only work with ((a) || (b)).
Furthermore when ltlcross would fail to parse a neverclaim containing
such a guard, it would fail to parse all later neverclaims, because
the lexer was not properly reset.
* src/neverparse/neverclaimscan.ll: Scan (a) || (b) as a single
token.

* src/tgbatest/neverclaimread.test: Add a test for (a) || (b).

Allow transitions between do..od, recognize atomic and assert.

Spin 6 supports formulas such as []<>(a < b) so that atomic properties
need not be specified using #define. Of course we don't want to
implement all the syntax of Spin in our LTL parser because other tools
may have different syntaxes for their atomic propositions. The
lenient mode tells the scanner to return any (...), {...}, or {...}!
block as a single token. The parser will try to recursively parse
this block as a LTL/SERE formula, and if this fails, it will consider
the block to be an atomic proposition. The drawback is that most
syntax errors will no be considered to be atomic propositions. For
instance (a U b U) is a single atomic proposition in lenient mode, and
a syntax error in default mode.
* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll,
src/ltlparse/parsedecl.hh, src/ltlparse/public.hh: Add a

So far all neverclaims encountered would use (!(x)), but the
files from the Büchi store do not.
