Once grabs start having nested memory locations, we can't just use the
GrabRec on the stack anymore, we need to alloc/copy/free the grabs.

Not really needed at this point, but will be once touch support is added.
Since grabs are now expected to be allocated/freed with AllocGrab and
FreeGrab, CopyGrab must increase the refcount and duplicate the modifier
masks. Until the callers are switched to use FreeGrab, this introduces
memleaks.

The record extension needs the major and minor opcodes in the reply
hook, but the request buffer may have been freed by the time the hook
is invoked. Saving the request major and minor codes as the request is
executed avoids fetching from the defunct request buffer.
This patch also eliminates the public MinorOpcodeOfRequest function,
inlining it into Dispatch. Usages of that function have been replaced
with direct access to the new ClientRec field.

There are plenty of cases that can only be triggered by a real bug in the
server and doing the ErrorF dance manually everywhere is a tad painful and
the error message is usually used only to find the spot in the file anyway.
Plus, reading BUG_WARN somewhere is a good indicator to the casual reader
that this isn't intended behaviour.
Note that this is intentionally different to the BUG_ON behaviour on the
kernel, we do not FatalError the server. It's just a warning + stacktrace.
If the bug is really fatal, call FatalError.

We don't need to first allocate a buffer 2 bytes bigger than the
string, copy the entire string unmodified to the buffer, print the

and then just in case we survived that, call exit as well, so the
leak is short lived, just oh so pointless).
