convert all code to use smb_{rq|t2}_alloc() instead of allocating
structures on stack, make smb_rq_init()/smb_t2_init() static and not
exported outside smb_rq.c
* add receive hook - if set, this function is called when request is finished
* unstatic smb_rq_enqueue(), smb_rq_reply() so that code can use that
independant of smb_rq_simple() et al
this is needed for NT DIRECTORY CHANGE NOTIFY SMB, since they typically
take very long to complete and we want to be able to use single kernel thread
to handle them all
add support for 'nowait' requests (flag SMBR_NOWAIT), which don't expect
and answer from server and are marked as 'processed' immediatelly
after they are sent to server - needed for NT CANCEL SMB
of iod calling smb_iod_sendall()
g/c now unneeded request timeout expire check from smb_iod_sendall()
make it possible to override default request timeout - set timeout
value in smb_rq_init() to default value, caller can adjust the value
before calling smb_iod_sendrq(); value <=0 means no timeout
* no need to use dummy variables for md_get_*(), just use NULL
* don't bother storing rpflags/rpflags2, it's not used anywhere
* g/c local variable rperror
malloc types into a structure, a pointer to which is passed around,
instead of an int constant. Allow the limit to be adjusted when the
malloc type is defined, or with a function call, as suggested by
Jonathan Stone.
