Fixes to r52065:
- Acquire resources within a critical region
- Simplified IoEnumerateRegisteredFiltersList and made its behaviour match the one described in MSDN: http://msdn.microsoft.com/en-us/library/ff548348%28v=vs.85%29.aspx
This was brought to you by Alex Ionescu.

- Fix a bug in device removal which resulted in an IRP_MN_CANCEL_REMOVE_DEVICE request not being sent if the initial IRP_MN_QUERY_REMOVE_DEVICE failed
svn path=/trunk/; revision=52066
- renamed Io volumes global to match Windows names (in case of debug)
- renamed IopDereferenceVpb() to IopDereferenceVpbAndFree(), IopReferenceVpbForVerify() to IopReferenceVerifyVpb(), IopInitializeVpbForMount() to IopMountInitializeVpb(), IopLoadFileSystem() to IopLoadFileSystemDriver()
- implemented IopDecrementDeviceObjectHandleCount(), IopInterlockedIncrementUlong(), IopInterlockedDecrementUlong(), IopNotifyAlreadyRegisteredFileSystems() and IoEnumerateRegisteredFiltersList()
- halfplemented IopDecrementDeviceObjectRef()
- implemented check for already registrered notification in IoRegisterFsRegistrationChange()
- implemented sending notifications for already registered drivers to registrant in IoRegisterFsRegistrationChange()
- implemented VPB freeing in IopDereferenceVpbAndFree()
- acquire Io volumes lists once and forever for system shutdown, instead of keeping acquiring and releasing
- reference device object in IopShutdownBaseFileSystems() before sending it the shutdown IRP. To ensure to keep it valid till the end
- added a FS driver registration operations counter
- use this counter to handle failed mounts
- fixed: release locks before calling driver for mounting and reacquire them after
- fixed check for boot partition failure (and associated bugcheck): check we are in boot phase 0 or 1
- simplified lock process by using only one lock (ie removed mutex). Also use only critical region where needed
- fixed: ensure that locks are properly released when quitting a function
- fixed wrong return in IopCreateVpb()
- minor fixes around

- Reset KdbNumberOfRowsPrinted and KdbNumberOfColsPrinted before reading new command in kernel debugger so if previous command printed nearly full page, new command won't show "Press q to abort" message before processing

"According to gcc doc, if header.h is precompiled, the output should be named "header.h.gch" and not anything else."
Knowing it was the first step before actually doing it :-/

fix pch support, with proper dependancies.
Use cmake built-in functions instead of doing weird "magic" with tabs and spaces.
According to gcc doc, if header.h is precompiled, the output should be named "header.h.gch" and not anything else.

Merge r52051 and r52052 from cmake branch:
* Improve static libs creation in *nix. Dedicated to arty.
* Add a missing dependency.
svn path=/trunk/; revision=52053
Merge r52027 from cmake branch:
* Several improvements to debug symbols handling.
* A new (killer/awesome/...etc) feature has been introduced to kdbg: argument values support. Now backtraces contain not only usermode and kernelmode addresses translated, but also the argument values passed to the functions along the trace.
* Brought to you by the Arty.
* works only with cmake builds

See issue #5807 for more details.
svn path=/trunk/; revision=52047
- Massive rework of device removal
- IRP_MN_QUERY_REMOVE_DEVICE is sent to all devices that will be removed in response to a removal/ejection
- If any of the IRP_MN_QUERY_REMOVE_DEVICE requests fail, all devices which received a IRP_MN_QUERY_REMOVE_DEVICE will receive IRP_MN_CANCEL_REMOVE_DEVICE
- If everything approves the remove request, IRP_MN_REMOVE_DEVICE will be sent to children, ejection and/or removal relations, and finally the device itself
- Handle removal relations for all devices not just 1st level devices
- Remove child devices before removing the parent
- Move GUID_DEVICE_REMOVE_PENDING and GUID_DEVICE_REMOVAL_VETOED notifications to IopQueryRemoveDevice
- Implement IopCancelRemoveDevice which sends IRP_MN_CANCEL_REMOVE_DEVICE to the driver stack and sends GUID_TARGET_DEVICE_REMOVE_CANCELLED to any drivers waiting on target device change
- Use the IopRemoveDevice function to remove devices instead of calling IopQueryRemoveDevice and IopSendRemoveDevice manually so removal and/or ejection relations and children are processed
- IRPs and PnP notifications sent upon device removal (surprise and safe) should now be compatible with XP/Vista/7
svn path=/trunk/; revision=52046
- Use tags when allocation and freeing memory and define them in tag.h
- Fix some wrongly used tags when freeing
- Our new memory manager doesn't check tags when ExFreePoolWithTag is used. It will be fixed after testing
svn path=/trunk/; revision=52043
in _flsbuf, always reset _cnt to 0 and don't allocate/use a buffer when _IONBUF is set. Fixes a regression in msvcrt_winetest file.
See issue #5829 for more details.
svn path=/trunk/; revision=52040
- Fix bug in PnpRegSzToString. The caller expects the result length to be the length of the string in bytes, not the string length
- Introduced in rev 46690
svn path=/trunk/; revision=52037
- Remove the device node when the device object is destroyed to prevent PnP manager from crashing when manipulating device nodes with device objects that no longer exist
- Move removal notifications into IopRemoveDevice and call it from IopPrepareDeviceForRemoval and IoRequestDeviceEject to manage all of the removal relations for each device removed
svn path=/trunk/; revision=52034
- Fix a bug in device removal and ejection which caused the request to fail when EjectionRelations or RemovalRelations was not handled by a driver in the stack
svn path=/trunk/; revision=52033
- Implement IopRemoveDevice and IopStopDevice
- Do a graceful remove before installing new drivers (like Windows does)
- Debug log warnings abound (don't be alarmed ;)) because drivers aren't used to receiving IRP_MN_QUERY_REMOVE_DEVICE, IRP_MN_REMOVE_DEVICE and IRP_MN_QUERY_PNP_DEVICE_STATE from our (formly) crippled PnP manager
svn path=/trunk/; revision=52029
- Handle IRP_MN_QUERY_REMOVE_DEVICE
- Handle IRP_MN_QUERY_PNP_DEVICE_STATE to report that we are not disableable to the PnP manager so we don't get removed during driver installation
svn path=/trunk/; revision=52028
- Set the DNF_DISABLED flag if a driver returns with the HardwareDisabled flag set to true (but only BEFORE starting the device)
- Don't try to start a device with the DNF_DISABLED flag set
- Send IRP_MN_QUERY_CAPABILITIES (again) and IRP_MN_QUERY_PNP_DEVICE_STATE after the device has started
- Write the UINumber and Capabilities registry entries in IopQueryDeviceCapabilities so they will be updated after every IRP_MN_QUERY_CAPABILITIES is sent
- Set the DNUF_DONT_SHOW_IN_UI flag in response to the NoDisplayInUI flag set in DEVICE_CAPABILITIES or PNP_DEVICE_DONT_DISPLAY_IN_UI set after sending IRP_MN_QUERY_PNP_DEVICE_STATE
- Set DNUF_NBOT_DISABLEABLE if PNP_DEVICE_NOT_DISABLEABLE is set after sending IRP_MN_QUERY_PNP_DEVICE_STATE
- Remove duplicate code
- Fix sending GUID_DEVICE_ARRIVAL (patch by Eric Kohl)
- IRPs sent to PnP devices on enumeration and start are now completely compatible with Windows XP/2003/Vista
svn path=/trunk/; revision=52026
- Launch a new listen IRP right after the current one completes instead of waiting until the current pending connection is accepted
- Reduces the chance of AFD missing two connection requests that are issued very close together and increases network performance by allowing our connection queue to do its job
svn path=/trunk/; revision=52013
- Implement sending GUID_TARGET_DEVICE_QUERY_REMOVE and GUID_TARGET_DEVICE_REMOVE_COMPLETE notifications
- Fix sending EventCategoryTargetDeviceChange notifications
- Remove some incorrect checks (IRP_MN_START_DEVICE CAN be called for a device that is already "started")
- Check the final status of the IRP_MN_START_DEVICE request sent after resource rebalancing and send IRP_MN_REMOVE_DEVICE if it fails
svn path=/trunk/; revision=52003
- Simplify remove lock tracking block list handling.
- Correct check for unlimited locking time being allowed.
- Eliminate use-after-free after removing a tracking block.
svn path=/trunk/; revision=52002
- dll/win32 and dll/shellext converted
- currently, only shell32 is left, due to incoming change to new version, and kernel32 - need to research how it should be done.
Tested on rbuild/cmake

- Fix a reference leak which prevented driver objects passed to IoRegisterPlugPlayNotification from being able to unload after the notification was unregistered
- Fix a non-paged pool leak
