It's not a good idea to enable high-entropy VA for tools loading the
Cygwin DLL dynamically. The addresses used by HEVA tend to collide with
fixed address areas managed by Cygwin.

CloseHandle gets redefined to a macro calling an internal function

Cygwin tool ssp generates gmon.out files with different address
resolution than other tools do. Two address bytes per bucket rather than
the usual four address bytes. Gprof can deal with the difference but
gmondump can't because the latter's gmon.out header validation fails.
- Remove the offending portion of the header validation code.
- Make sure all code can handle differing address resolutions.
- Display address resolution in verbose data dumps.
- Change "rawarc" to "struct rawarc" in certain sizeof expressions to
avoid buffer overrun faults.
- When "-v" (verbose) is specified, note when there is missing bucket
data or rawarc data.
These have no effect on x86_64. Retain a few occurrences of __cdecl
in files imported from other sources.
Also retain all occurrences of WINAPI, even though the latter is
simply a macro that expands to __stdcall. Most of these occurrences
are associated with Windows API functions, and removing them might
make the code confusing instead of simpler.
Link directly with RegDeleteKeyExW(), available since Vista.
(It's unclear the LoadLibrary wrapper was ever doing anything useful
here, as (i) DLL lookup in PATH was avoided as advapi32 is already
loaded into the process, and (ii) advapi32 is a 'known DLL' which is
only ever loaded from system directory)
- Previously, the command "cmd /c script -c cmd" in console of Win7
crashes. This seems to be due to a bug (?) of AttachConsole().
This patch adds workaround for this issue.
Currently, pty reattaches to the console of the process which is
predetermined by ConsoleProcessList() after temporarily attaching
to another console. After that, the console output handle opened
with the name "CONOUT$" may not be accessible in Win7.
This seems to happen when the attached process does not have the
same handle even if the console attached is the same. With this
patch, cygwin-console-helper which is started when pty master is
opened in console, is utilized to be a target process to which
pty reattaches if the OS is Win7.
This was a hack to begin with. Clean this mess up:
- Move definition of CYGTLS_PADSIZE to cygwin/config.h and drop
local cygtls_padsize.h
- Rename CYGTLS_PADSIZE to __CYGTLS_PADSIZE__ to keep namespace
clean. Redefine as macro, rather than as const.
- Move struct _reent first in struct _cygtls to allow using
__CYGTLS_PADSIZE__ as offset in __getreent().

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.)
The doc for gmondump says 1 or more FILENAME are expected, but 0 is
handled. That's an oversight. Make invocation with 0 FILENAMEs print a
one-line help message.
Reword the beginning of profiler's description doc to clarify target's
child processes are run but only optionally profiled.
DWORD has different types on 32 and 64 bit. Use a common cast to
unsigned long to use %lu format for DWORD values throughout.

These are updates to wire into the build tree the new tools profiler and
gmondump, and to supply documentation for the tools.
The documentation for profiler and ssp now mention each other but do not
discuss their similarities or differences. That will be handled in a
future update to the "Profiling Cygwin Programs" section of the Cygwin
User's Guide, to be supplied.
This new tool was formerly part of 'profiler' but was spun out thanks to
Jon T's reasonable review comment. Gmondump is more of a debugging tool
than something users might have need for. Users would more likely use
gprof to make use of symbolic info like function names and source line
numbers.
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.
The default PSAPI_VERSION is controlled by WIN32_WINNT, which we set to
0x0a00 when building utils since 48a76190 (and is the default in w32api
>= 9.0.0)
In order for the built executables to run on Windows Vista, we must also
define PSAPI_VERSION as 1 (otherwise '#define GetModuleFileNameExA
K32GetModuleFileNameExA' causes a 'The procedure entry point
K32GetModuleFilenameExA could not be located in the dynamic link library
kernel32.dll' error at run time).
Also drop uneeded psapi.h from dlfcn.cc (31ddf45d), resource.cc
(34a6eeab) and ps.cc (1def2148).
The default PSAPI_VERSION is controlled by WIN32_WINNT, which we set to
0x0a00 when building ldd, which gets PSAPI_VERSION=2.
This causes K32GetModuleFileNameEx to be used for GetModuleFileNameEx,
which isn't available on Windows Vista.
Define PSAPI_VERSION as 1 for the built executable to work on Windows
Vista.

Move all the source files used in utils/mingw/ into that subdirectory,
so the built objects are in the expected place.
(path.cc requires some more unpicking, and even then there is genuinely
some shared code, so use a trivial file which includes the real path.cc
so the object file is generated where expected)
Rather than having testsuite.h do various things, depending on defines,
just have it do one thing, and then explicitly redirect to test stubs in
path.cc when building test.
