commit d1be0a59d4,
"Cygwin: winpids: Fix getting process multiple times"
fixed duplicate processes in ps -W output, but it fixed
the symptom, not the cause. It also didn't fix the problem
that the `ps' process itself may show up twice in its own
output.
This patch fixes it. The spawn worker only deleted the
"winpid.PID" symlink of the current process if the child is
a non-Cygwin process, under the assumption that the exec'ing
process exits anyway. However, the Window in which both
winpid.PID symlinks point to the same cygpid.PID area is just
too long. The spawn worker now also deletes its own winpid.PID
symlink if the exec'ed process is a Cygwin process.
Additionally the fix from d1be0a59d4
is now performed on the calling process, too.

Switching to Cywin-only PIDs introduced a new problem when collecting
Cygwin processes for `ps -W': A process can show up multiple times
again, if the Cygwin procinfo has been opened for a just execing
process. The execed process then shows up twice, once as Cygwin
process, but with the wrong Windows PID of the execing process,
once as Windows-only process.
The mechanism used to exclude these stray processes didn't work with
the new Cygwin pid handling anymore. To fix this
* check if the incoming Windows PID is the same as the PID in the
procinfo. If not, we have the PID of the execing process while
procinfo was already changed,
* always check if the process has already been handled, not only
for processes we got a procinfo for,
* simplify adding pid to pidlist since pid is now always correct.
While at it, fix comments and comment formatting.

The winpid symlinks got created with no query permissions, so
only admins could see all Cygwin processes. Create symlinks

When calling spawnve, in contrast to execve, the parent has
to create the pid for the child. With the old technique
this was simply the Windows pid, but now we have to inform
the child about its new pid.
Add a cygpid member to class child_info_spawn. Set it in
child_info_spawn::worker, just prior to calling CreateProcess
rather than afterwards. Overwrite cygheap->pid in
child_info_spawn::handle_spawn before calling pinfo::thisproc.
Make sure pinfo::thisproc knows the pid is already set by
setting the handle argument to INVALID_HANDLE_VALUE.
Also set procinfo->dwProcessId to myself_initial.dwProcessId
instead of to myself_initial.pid for clarity.

In preparation to protect fork() against dll- and exe-updates, create
hardlinks to the main executable and each loaded dll in subdirectories
of /var/run/cygfork/, if that one exists on the NTFS file system.
The directory names consist of the user sid, the main executable's NTFS
IndexNumber, and the most recent LastWriteTime of all involved binaries
(dlls and main executable). Next to the main.exe hardlink we create the
empty file main.exe.local to enable dll redirection.
The name of the mutex to synchronize hardlink creation/cleanup also is
assembled from these directory names, to allow for synchronized cleanup
of even orphaned hardlink directories.
The hardlink to each dynamically loaded dll goes into another directory,
named using the NTFS IndexNumber of the dll's original directory.

Since commit b5e1003722, native
Windows processes not started by Cygwin processes don't have a
Cygwin PID anymore. This breaks ps -W and kill -f <WINPID>.
Introduce MAX_PID (65536 for now).
Cygwin processes as well as native Windows processes started
from a Cygwin process get a PID < MAX_PID. All other native
Windows processes get a faked Cygwin PID >= MAX_PID.

Using the Windows PID as Cygwin PID has a few drawbacks:
- the PIDs on Windows get reused quickly. Some POSIX applications choke
on that, so we need extra code to avoid too quick PID reuse.
- The code to avoid PID reuse keeps parent process handles and
(depending on a build option) child processes open unnecessarily.
- After an execve, the process has a split personality: Its Windows PID
is a new PID, while its Cygwin PID is the PID of the execve caller
process. This requires to keep two procinfo shared sections open, the
second just to redirect process info requests to the first, correct
one.
This patch changes the way Cygwin PIDs are generated:
- Cygwin PIDs are generated independently of the Windows PID, in a way
expected by POSIX processes. The PIDs are created incrementally in
the range between 2 and 65535, round-robin.
- On startup of the first Cygwin process, choose a semi-random start PID
for the first process in the lower PID range to make the PIDs slightly
unpredictable. This may not be necessary but it seems kind of inviting
to know that the first Cygwin process always starts with PID 2.
- Every process not only creates the shared procinfo section, but also a
symlink in the NT namespace, symlinking the Windows PID to the Cygwin
PID. This drops the need for the extra procinfo section after execve.
- Don't keep other process handles around unnecessarily.
- Simplify the code creating/opening the shared procinfo section and
make a clear distinction between interfaces getting a Cygwin PID and
interfaces getting a Windows PID.

To allow reopening a file open in another process by HANDLE, introduce
a matching file_pathconv method, taking a file descriptor as parameter.
The result is a serialized path_conv and a HANDLE value. The HANDLE is
valid in the foreign process and MUST be duplicated into the target
process before usage.

Revamp device parsing code. Introducing support for more partitions
into the shilka-generated parser has the unfortunate side-effect of
raising the size of the DLL by almost 2 Megs. Therefore we split out
the handling for /dev/sdXY devices into a tiny bit of hand-written
code.
While at it, remove some unused cruft from devices.* and generally
clean up the device class to provide access methods instead of direct
access to members.
