directly, so we don't need that extra function anymore.

Drop the -reset flag, so Xserver now either simply continues (w/o going
through internal reset) when last client disconnected or terminates
when -terminate is given.

Move this to a little function (which also has a better name now)
inside the already platform specific ossock.c
Also removing the EMSGSIZE check: we're using TCP or local unix
socket, so EMSGSIZE is never returned.

It's only used by record extension, not used by any drivers at all
(neither FOSS nor proprietary), so it shouldn't be in the public SDK.
Since it's never been used by any driver, it's effectively no ABI change,
so we can safely do this within ABI-25.

Since we already know the string length, we can just use memcpy()

Existing client-state hook isn't sufficient for this, and so easy to
be extended cleanly (*1). Adding a new callback is trivial and cheap,
so preferring this way, instead of trying to tweak the existing hook
for something it's never been designed for.

arc4random_buf() is a pretty standard libc function on Unix'oid platforms,
but not all our targets have it, thus we need a fallback there. Currently we
have GenerateRandomData(), which either just wraps arc4random_buf() or provides
some fallback implementation.
For those cases it's easier to just implement missing functions directly
instead of having custom wrapper functions. So, drop GenerateRandomData()
in favor of arc4random_buf() and provide fallback implementation for where
it is missing.

Since everything's running via Writev() methods now, the now unused Write()
methods can all be dropped.
Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
Now that all WriteV() methods are operating on single buffer instead ofiovec's,
we don't need the complicated _XSERVTransWriteV() anymore, but instead can
write directly to the socket/fd.
Signed-off-by: Enrico Weigelt, metux IT consult <info@metux.net>
Since they're only called with a one-element iovec, we can use a single
buffer pointer straight away, thus making it quite the same as the old
Write() methods.

_XSERVTransWrite() is only intended as frontend, for xtrans consumers to
call in here. And upcoming commits will change that function to call the
Writev() method instead of Write(), so we would end up in infinite
recursing if we'd still it it here.

The global (exported) serverGeneration field is `unsigned long`, while
many other places copy it and compare it two other integer types, eg.
plain `int` (which is signed). Even if it's unlikely ever reaching such
high number of generations that it will ever make trouble, it's still
a good idea to clean this up and use the same type everywhere.
For clearity, introducing a typedef `x_server_generation_t` which is
used everywhere, instead of raw `unsigned long`.

Flushclient implicitly cast the result from a write-like call
to size_t, which turned it's error return value, -1,

Since FlushClient only writes the data in the client's buffer,
with no extra data or padding, we only write at most as many bytes
as there are in the client buffer.
we just have to set oco->count to notWritten, the amount we still
have to write.
