option handling to use the same style throughout all Cygwin utils.

* strace.cc (proc_child): Avoid compiler warning.
(display_internet_error): Use proper format specifier for DWORD.
(environ): Remove unneeded declaration.
(main): Use brace around nested if to avoid an overly-helpful compiler warning.
* dump_setup.cc (parse_filename): Reorganize nested if to avoid an
overly-helpful compiler warning.
* path.cc (GUID_shortcut): Use braces around part of initializer which needs
them.
(conv_fstab_spaces): Parenthesize assignment in while loop to avoid a compiler

(struct opt): Make static.
* ps.cc (main): Reorganize nested if to avoid an overly-helpful compiler
warning.

* ssp.c (lookup_thread_id): Initialize *tix to zero to avoid potential
uninitialized use.
* strace.cc (add_child): Use proper format specifier for DWORD.
(remove_child): Ditto.
(proc_child): Ditto.
Change appropriate globals to statics throughout.
* cygcheck.cc (usage): Simplify usage output. Generalize to allow use for
help.
(longopts): Add version option.
(opts): Add 'V" version option.
(print_version): New function.
(main): Accommodate new version option. Accommodate usage parameter changes.
Use usage to output help message.
