Mark Geisert 94ead7b76d Cygwin: More profiler format + small issue fixes
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.)

Corinna Vinschen bf8f2a95df Cygwin: profiler: Fix formatting warnings
DWORD has different types on 32 and 64 bit.  Use a common cast to
unsigned long to use %lu format for DWORD values throughout.

Cygwin: New tool: profiler
The new tool formerly known as cygmon is renamed to 'profiler'.  For the
name I considered 'ipsampler' and could not think of any others.  I'm open
to a different name if any is suggested.

I decided that a discussion of the pros and cons of this profiler vs the
existing ssp should probably be in the "Profiling Cygwin Programs" section
of the Cygwin User's Guide rather than in the help for either.  That
material will be supplied at some point.

CONTEXT buffers are made child-specific and thus thread-specific since
there is one profiler thread for each child program being profiled.

The SetThreadPriority() warning comment has been expanded.

chmod() works on Cygwin so the "//XXX ineffective" comment is gone.

I decided to make the "sample all executable sections" and "sample
dynamically generated code" suggestions simply expanded comments for now.

The profiler program is now a Cygwin exe rather than a native exe.
