Add the capability to trigger deferred error interrupts and
threshold interrupts in order to test the APIC interrupt handler
functionality for these type of errors.
Update README section about the same too.

[ Cleanup comments. ]
[ Include asm/irq_vectors.h directly so that misc randbuilds don't fail. ]

Invalid inputs such as these are currently reported in dmesg as
failing:
$> echo sweet > flags
[ 122.079139] flags_write: Invalid flags value: et
even though the 'flags' attribute has been updated correctly:
$> cat flags
sw
This is because userspace keeps writing the remaining buffer
until it encounters an error.
However, the input as a whole is wrong and we should not be
writing anything to the file. Therefore, correct flags_write()
to return -EINVAL immediately on bad input strings.

This is an x86-specific module and would benefit from being
closer to the arch code. Move it there. Update copyright while
at it.
