  lex tests: avoid possible hang; fix and extend
  
  * tests/lex3.test (foo.l:yywrap): Return 1, not 0, to avoid hangs.
  Bug introduced in commit 'v1.11-871-geb147a1'.
  (Makefile.am): Do not add `@LEXLIB@' to `$(LDADD)', as we define
  our own `yywrap' function.
  * tests/lex.test (tscan.l): In `yywrap', return 1, not 0, for
  consistency with the default flex implementation.
  * tests/lex-libobj.test (yywrap.c): Likewise.
  * tests/lex-subobj-nodep.test (s1.l): Likewise.
  * tests/lexvpath.test (foo.c): Likewise.
  * tests/silent-lex-gcc (foo.l): Likewise.
  * tests/silent-lex-generic (foo.l): Likewise.
  * tests/silent-many-gcc (foo5.l): Likewise.
  * tests/silent-many-generic (foo5.l): Likewise.
  * tests/lex-lib.test (mu.c): Likewise.
  Update heading comments, to refer to ...
  * tests/lex-lib-external.test: ... this new test, which checks
  that we can get use the `yywrap' function from a system-wide
  library, if that's available.
