Log:
[RTL/NTDLL/KERNEL32]: Rtl provides worker queue and timer queue functionality, which
queues a worker thread associated with a caller-supplied callback. In Windows, Rtl by
default calls RtlCreateUserThread, but as soon as kernel32 loads, it's DllMain calls
an exported function RtlSetThreadPoolStartFunc which changes that default to a special
Base function that calls CreateRemoteThread instead. The net result is that Win32
processes using the Rtl functionality get their threads properly registered with CSRSS. In
ReactOS, this did not happen, so when those threads called into CSRSS, CSRSS had no
CSR_THREAD structure/state for them, which is why CsrCreateThread (and the API loop) are
so badly hacked. This commit implements RtlSetThreadPoolStartFunc, implements the kernel32
base functions which wrap CreateRemoteThread, and implements the rtl functions which wrap
RtlCreateUserThread. Services, Setup, and any ReactOS application using RPC now have the
worker threads correctly registered.
