[SMDLL][SMLIB] Deprecate the legacy ROS-specific SMDLL and improve SM client
functions. (#4821)
This DLL was exporting legacy NT-incompatible or ROS-specific SM client
functions, that have been since 10 years now (2012) replaced by the new
NT-compatible SM:
- SmConnectApiPort(): was just SmConnectToSm().
- SmCompleteSession():
The legacy SMSS used it for when a subsystem initialization was finished.
Now (NT-compatible) this function is called by subsystems **only** when a
subsystem session **terminates**: SmSessionComplete().
- SmExecuteProgram(): was just the client side of SmLoadDeferedSubSystem()
(whose server side is not implemented yet). The legacy SM "old" SmExecPgm
implementation actually was "SmLoadDeferedSubSystem"...
- SmLookupSubsystem(): is a utility-only function to read any registry value
inside "Session Manager\SubSystems".
Move SMDLL's readme into SMLIB and update its contents.
Collect some residual useful functions into smutils.c (and moved in SMLIB,
though not compiled yet):
- SmExecuteProgram(), now implemented as a wrapper around SmExecPgm();
- SmLookupSubsystem(), described above;
- SmQueryInformation(), that retrieves a list of currently-running subsystems.
[SMLIB] Validate SbApiPortName's length in SmConnectToSm().
Fix CommandLine length validation in SmStartCsr().
Add documentation (+ SAL annotations) to the NT-compatible SMSS client functions.
smmsg.h: Add both Win32 and Win64 struct sizes C_ASSERTs for those whose size
change between these two processor architecture sizes.
[SMLIB] Introduce SmSendMsgToSm() as helper to send data into the SM LPC port.
+ Make the other API functions use it.
It should be observed that in Vista+, both functions SmConnectToSm() and this
new SmSendMsgToSm() are exported by NTDLL under the names RtlConnectToSm()
and RtlSendMsgToSm() (and use the same signature).
See: https://www.geoffchappell.com/studies/windows/win32/ntdll/history/names60.h…
[NTDLL] Correctly stub RtlConnectToSm() and RtlSendMsgToSm().
[NTDLL_VISTA] Link to SMLIB and simply export RtlConnectToSm() and RtlSendMsgToSm().

-This is SMDLL: a helper library to talk to the ReactOS session manager (SM).

-It should be linked in the following components:
-
-a) the SM itself, because it registers for managing native processes
- IMAGE_SUBSYSTEM_NATIVE;
-
-b) environment subsystem servers, because each one should register in
- the SM its own subsystem (willing to manage those processes);
-
-c) terminal emulators for optional subsystems, like posixw32 and os2w32,

+SMLIB: Client Library to talk to the ReactOS NT-Compatible Session Manager (SM).
+
+It should be linked in the following components:
+
+a) the SM itself, because it registers for managing native processes
+ IMAGE_SUBSYSTEM_NATIVE;
+
+b) environment subsystem servers, because each one should register in
+ the SM its own subsystem (willing to manage those processes);
+
+c) application launchers (e.g. terminal emulators) for optional subsystems,
+ to ask the SM to start the optional subsystem server they need to connect;
+
+d) system and development utilities to debug/query the SM.

+
+
+How a subsystem uses these APIs
+===============================
+
+Thread #0 Thread #1
+
+- Creates its own directory (\EXAMPLE)
+- Initializes the main parts of the subsystem.
+- Creates its main API port (\EXAMPLE\ApiPort),
+ and servicing thread for it. Programs running
+ under this subsystem will communicate with
+ this API port.
+
+- Creates its SM callback API port (\EXAMPLE\SbApiPort)
+ and servicing thread T1.
+
+ - Waits connection requests on the
+ callback port (\EXAMPLE\SbApiPort)
+
+- Registers to the SM by calling
+ SmConnectToSm(
+ "\EXAMPLE\SbApiPort",
+ hSbApiPort,
+ SUBSYSTEM_ID,
+ &hSmApiPort);
+ - As the SM calls back, validates
+ and accepts connection.
+
+- The subsystem is now ready to
+ manage processes, etc.
+
+-----
+
+Thread #N Thread #1
+
+ - The SM calls back the subsystem
+ SbCreateSession() API, so that it
+ can initialize a new environment
+ session (with associated SessionId).
+
+- When no more processes to manage exist,
+ terminate the subsystem session by calling
+ SmSessionComplete(
+ hSmApiPort,
+ SessionId,
+ ExitStatus);
+ - The SM calls back the subsystem
+ SbTerminateSession() API.

+ * @brief
+ * Connects to the SM API port for registering a session callback port (Sb)
+ * associated to a subsystem, or for issuing API requests to the SM API port.
+ *
+ * There are only two ways to call this API:
+ * a) subsystems willing to register with SM will use it
+ * with full parameters (the function checks them);
+ * b) regular SM clients, will set to 0 the 1st, the 2nd,
+ * and the 3rd parameters.
+ *
+ * @param[in] SbApiPortName
+ * Name of the Sb port the calling subsystem server already
+ * created in the system namespace.
+ *
+ * @param[in] SbApiPort
+ * LPC port handle (checked, but not used: the subsystem is
+ * required to have already created the callback port before
+ * it connects to the SM).
+ *
+ * @param[in] ImageType
+ * A valid IMAGE_SUBSYSTEM_xxx value. PE images having this
+ * subsystem value will be handled by the current subsystem.
+ *
+ * @param[out] SmApiPort
+ * Pointer to a HANDLE, which will be filled with a valid
+ * client-side LPC communication port.
+ *
+ * @return
+ * If all three optional values are omitted, an LPC status.
+ * STATUS_INVALID_PARAMETER_MIX if PortName is defined and
+ * both SbApiPort and ImageType are 0.
+ *
+ * @remark
+ * Exported on Vista+ by NTDLL and called RtlConnectToSm().
