Cygwin: More profiler format + small issue fixes

Browse Source 
Make sure to cast to ulong all DWORD values displayed with format "%lu".
More instances are fixed here than in either my earlier unused patch or
Corinna's patch. I decided to use typedef..ulong for more compact code.

Address jturney's reported small issues:
- Remove explicit external ref for cygwin_internal() as it is already
  provided by <sys/cygwin.h>.
- Leave intact ref for cygwin_dll_path[] as it is required by function(s)
  in path.cc that profiler uses. Added comment to that effect.
- Delete existing main() wrapper. Rename main2() to main(). This because
  profiler is now a Cygwin program and doesn't need to dynamically load
  cygwin1.dll.
- Documentation issues will be addressed in a separate xml patch.

(I would have linked message-ids of Corinna's and Jon's messages for
proper theading but I no longer have their original emails and the mail
archives don't show msgids any more.)
