Oneliner of the day... This typo just prevented the
whole feature to work properly. Because any allocated
work item would miserably fail to be freed.
This will obviously help real world FSD relying on
StackOverflow worker from FsRtl to work better!

NETAPI32: Get rid of the old WINE NetServerGetInfo and replace it by a proper call to NetrServerGetInfo.
SRVSVC: Implement parts of NetrServerGetInfo.
srvsvc.idl: Hack around a bug in midl or rpcrt4. They are not able to handle a pointer to a union of pointers to structs. A pointer to a union of structs works a advertised.
- Make the reply buffer for IcmpSendEcho large enough to hold the reply,
even when testing a smaller size. This avoids a buffer overflow with ROS's
broken implementation.
- Avoid unnecessary initialization.
- Fix IcmpSendEcho return value check to succeed on Win2003.
- Don't free a string literal in the GetInterfaceName test.
In the lazy writer run, first post items that are queued for this.
Only then, start executing deferred writes if any.
If there were any, reschedule immediately a lazy writer run, to keep
Cc warm and to make it unqueue write faster in case of high IOs situation.
To make second lazy writer run happen faster, we keep our state active to
use short delay (1s) instead of standard idle (3s).
ScControlService:
- SEH-protext the calls to service control handlers.
- Return ERROR_EXCEPTION_IN_SERVICE if a service control handler throws an exception.
- Return ERROR_SERVICE_CANNOT_ACCEPT_CTRL if no service control handler has been registered for the service.
- RI_ScSetServiceBitsA: Just call RI_ScSetServiceBitsW.
- RI_ScSetServiceBitsW: Store the service bits in the service list entry.
TODO: Merge all service bits in a global variable and pass it to the server service. Maybe use netapi.I_NetServerSetServiceBits(Ex)?
Recent changes seem to show that it's not
required to be exclusive on VACB to be able
to flush it.
This commit goes with f2c44aa and fixes the
last issues going with copying huge files.
There are no longer BSODs (be it in Mm or Cc).
I could, with 750MB RAM extract a 2GB file from
a 53MB archive and copy a 2,5GB file from a VBox
share to the disk. Note that writes are often
deferred, so if copy works, it's not that fast for now.
Note that it also brings some beloved behavior from
Windows: copy times are totally unreliable now when
writes are deferred. Little remaining times when
actively copying, high remaining times when deferred
writes in action. And goes between both... Sorry! ;-)

Same mechanism exists in Windows (even their Cc
is way different from ours...) where when Cc is
out of memory (in their case, out of VACB), we
will start scavenge old & unused VACB to free
some of the memory.
It's useful in case we're operating we big files
operations, we may run out of memory where to map
VACB for them, so start to scavenge VACB to free
some of that memory.
With this, I am able to install Qt 4.8.6 with 2,5GB of RAM,
scavenging acting when needed!

Before any write operation that would involve caching, ask
the cache controler whether writing would make it exceed its memory
consumption. If so, queue the write operation for later execution.
In case the write operation can wait, then, the FSD operation will be
halted until the write is allowed.
I could test it successfully by copying huge files from a FAT volume to
another. The write is halted until some portions of the file is written
to the disk.
I could also properly install Qt (SDK) on ReactOS with this and less than 1GB RAM:

Adjusting refcount and enabling lazy-write for pinned
VACB makes it actually more efficient, often purging
data to disk, reducing memory stress for the system.
This is required for defering writes.
This commit unfortunately (?) reverts a previous revert.
