4c3fb2a591 pidl: set the per-request memory context in the pidl generator
The talloc memory context referenced by the pipe_struct mem_ctx member is used
as talloc parent for RPC response data by the RPC service implementations.

In Samba versions up to 4.10 all talloc children of p->mem_ctx were freed after
a RPC response was delivered by calling talloc_free_children(p->mem_ctx). Commit
60fa8e255254d38e9443bf96f2c0f31430be6ab8 removed this call which resulted in all
memory allocations on this context not getting released, which can consume
significant memory in long running RPC connections.

Instead of putting the talloc_free_children(p->mem_ctx) back, just use the
mem_ctx argument of the ${pipename}_op_dispatch_internal() function which is a
dcesrv_call_state object created by dcesrv_process_ncacn_packet() and released
by the RPC server when the RPC request processing is finished.

72540222c2 lib: Properly return errno from open_socket_in()
Before this patch, open_socket_in() relied on quite a bit of code to
not touch errno after for example socket() returned -1. Change this to
explicitly save errno in "ret", such that a later DEBUG() with all its
formatting code can mess it up.

While there, remove the debuglevel parameter. I don't think this
actually useful.

b5705cc70c srvsrvc: Reload conf after changing a share
The call to messaging_send_all() skips ourselves. This is tested in
source3/script/tests/test_rpcclientsrvsvc.sh, which right now we only
survive because the rpcclient call spawns a new smbd, which reloads
smb.conf. Once you start running srvsvcd in a long-running daemon,
this fails.
