Fix mountd so that it will not lose SIGHUPs that indicate "reload exports".
Without this patch, if a SIGHUP is handled while the process is executing
get_exportlist(), that SIGHUP is essentially ignored because the got_sighup
variable is reset to 0 after get_exportlist().
This results in the exports file(s) not being reloaded until another SIGHUP

This patch fixes this by resetting got_sighup to zero before the
get_exportlist() call while SIGHUP is blocked.
It also defines a delay time of 250msec before doing another exports reload
if there are RPC request(s) to process. This prevents repeated exports reloads

MFC r362337: Make polled request timeout less invasive.
Instead of panic after one second of polling, make the normal timeout
handler to activate, reset the controller and abort the outstanding
requests. If all of it won't happen within 10 seconds then something
in the driver is likely stuck bad and panic is the only way out.
In particular this fixed device hot unplug during execution of those
polled commands, allowing clean device detach instead of panic.
In the receive interrupt routine, always call netmap_rx_irq().
The latter function will return != NM_IRQ_PASS if netmap is not
active on that specific receive queue, so that the driver can go
on with iflib_rxeof(). Note that netmap supports partial opening,
where only a subset of the RX or TX rings can be open in netmap mode.
Checking the IFCAP_NETMAP flag is not enough to make sure that the
queue is indeed in netmap mode.
Moreover, in case netmap_rx_irq() returns NM_IRQ_RESCHED, it means
that netmap expects the driver to call netmap_rx_irq() again as soon
as possible. Currently, this may happen when the device is attached
to a VALE switch.
The nm_register callback needs to call nm_set_native_flags()
or nm_clear_native_flags() once the device has been stopped.
However, in the current implementation this is not true,
as the device is stopped by vtnet_init_locked(). This causes
race conditions where the driver crashes as soon as it
dequeues netmap buffers assuming they are mbufs (or the other
way around).
To fix the issue, we extend vtnet_init_locked() with a second
argument that, if not zero, will set/clear the netmap flags.
This results in a huge simplification of the nm_register
callback itself.
Also, use netmap_reset() to check if a ring is going to be
re-initialized in netmap mode.
