4a9b5cce92 config: The AIO engine is indepent of HAVE_AIO now 
Compile the basic aio engine always, it works via libasys/pthreadpool_sync
in a sync fashion even if no pthreads are around. Everything else (linux
aio, posix aio, aio fork) is now compiled as modules based on specific
system capabilities

d0d05f8474 s4-lib/tls: Try socket_send() multiple times to send partial packets 
This works around an artificial limitation in socket_wrapper that breaks
some versions of GnuTLS when we return a short write.

Instead, keep pushing until the OS will not take it.

The correct solution will be to use tls_tstream, but the client code
for this is not yet tested and needs the ldap client layer changed
to use it.

02a356ea77 s4-librpc: Ensure we do not call call the decrpc timeout handler during gensec_update() 
This avoids a situation where we could destroy pointers on the stack due to
a nested event loop.

This is certainly not a final, generic solution, but it is a minimal change
while we work to make gensec and gensec_gssapi async.

e4001a78c1 dsdb: Allocate new OID to allow updates of a read-only replica

96db13405b s4-dsdb: Ensure we never write read-only objects onto a read-write replica 
We should prevent this much further up the stack, but at least add a choke
at this point for now.

Additionally, this avoids administrator-forced replications causing
considerable damange to the directory.

dbwrap needs it.  Some calls were already wrapped, but they checked the

func(...) {

99272331c6 source3/passdb/py_passdb.c: don't steal from talloc_stackframe(). 
If you want a stack-style allocation, use talloc_stackframe().  If you
don't, don't use it.  In particular, talloc_stackframe() here is actually
inside a pool, and stealing from pools is a bad idea.
