Impact: fix rare crash on 32-bit

The 32-bit APIC drivers had their send_IPI_self vectors set to NULL,
but ioapic_retrigger_irq() depends on it being always set. Fix it.

Impact: 32-bit should use logical version

there are two version: for default_send_IPI_mask_sequence/allbutself
one in ipi.h and one in ipi.c for 32bit

it seems .h version overwrote ipi.c for a while.

restore it so 32 bit could use its old logical version.
also remove dupicated functions in .c

Nothing exciting - a few subarches dont want APIC remote reads to
be performed - the others are content with the default method.

Only NUMAQ does something substantial here, because it initializes
via NMIs (not via INIT as standard SMP startup) - so it needs to
store and restore the NMI vector.

Refactor the ->phys_pkg_id() methods:

Only ES7000 has a real ->enable_apic_mode() method, the other
subarchitectures define it but keep it empty.

So mark the vector as NULL, extend the generic code to handle
NULL -setup_portio_remap() entries and remove all the empty
handlers.

only NUMAQ uses this quirk: to prevent the timer IRQ from being added

All other genapic templates can have a NULL ->multi_timer_check()
callback.

Also, extend the generic code to treat a NULL pointer accordingly.

Impact: cleanup

The bigsmp and es7000 subarchitectures un-defined APIC_DEST_LOGICAL in
a rather nasty way by re-defining it to zero. That is infinitely
fragile and makes it very hard to see what to code really does in
a given context. The very same constant has different meanings and
values - depending on which subarch is enabled.

Untangle this mess by never undefining the constant, but instead
propagating the right values into the genapic driver templates.

Signed-off-by: NIngo Molnar <mingo@elte.hu>

Impact: cleanup

Most subarchitectures want to disable the APIC ESR (Error Status Register),
because they generally have hardware hacks that wrap standard CPUs into
a bigger system and hence the APIC bus is quite non-standard and weirdnesses
(lockups) have been seen with ESR reporting.

Remove the esr_disable macros and put the desired flag into each
subarchitecture's genapic template directly.
