unp_dispose and unp_gc could race to teardown the same mbuf chains, which
can lead to dereferencing freed filedesc pointers.
This patch adds an IGNORE_RIGHTS flag on unpcbs marking the unpcb's RIGHTS
as invalid/freed. The flag is protected by UNP_LIST_LOCK.
To serialize against unp_gc, unp_dispose needs the socket object. Change the
dom_dispose() KPI to take a socket object instead of an mbuf chain directly.

IDs in initiator mode -- index in port database instead of handlers.
This makes initiator IDs persist across role changes and firmware resets,
when handlers previously assigned by firmware are lost and reused.

o Return the real hardware state in gpio_pin_getflags() instead of keep
the last state in an internal table. Now the driver returns the real
state of pins (input/output and pull-up/pull-down) at all times.
o Use a spin mutex. This is required by interrupts and the 1-wire code.
o Use better variable names and place parentheses around them in MACROS.
o Do not lock the driver when returning static data.
Tested with gpioled(4) and DS1820 (1-wire) sensors on banana pi.
If a signal is caught in pipelock, causing it to fail, pipe_direct_write
should not try to pipeunlock.

Aside from cleaner and more consistent code, this allows ports to be both
target and initiator same time, and easily switch from any role to any.

This means needing to be careful about buffers and keeping track
of external read request length.
