Fix indentation in SYNOPSIS.

Updated to include changes of latest BSD mdoc version (basically,
`.Fn' and `.Fc' put a final semicolon after a function declaration
in the SYNOPSIS section.

* tmac/doc.tmac (doc-in-synopsis-count): Replaced with ...
(doc-in-synopsis-section): New variable.  Updated all related
functions.
(doc-indent-synopsis-active): New register.
(Nd, Fn, Fo): Use it.
(Cd): It requires manipulation of n[doc-indent-synopsis] so that
`.Cd' with long argument line produces indented wrapped lines.
Also, the misplaced `.nop *[doc-Nm-font]c'' caused extra
undesirable line break to be output.
(doc-do-func-decl, Nm, Vt, Fn, Fo): Remove extraneous calls to
`.rs'.
(Fn, Fc): Add final `;' to output.
(doc-save-global-vars, doc-restore-global-vars): Updated.
* tmac/doc-common: Remove `Ex' register.
Updated.
* tmac/doc-ditroff, tmac/doc-nroff, tmac/doc-syms: Updated
copyright.
