vsprintf: Change struct printf_spec.precision from s8 to s16
Commit ef0658f3de484bf9b173639cd47544584e01efa5 changed precision
from int to s8.
There is existing kernel code that uses a larger precision.
An example from the audit code:
vsnprintf(...,..., " msg='%.1024s'", (char *)data);
which overflows precision and truncates to nothing.
Extending precision size fixes the audit system issue.
Other changes:
Change the size of the struct printf_spec.type from u16 to u8 so
sizeof(struct printf_spec) stays as small as possible.
Reorder the struct members so sizeof(struct printf_spec) remains 64 bits
without alignment holes.
Document the struct members a bit more.
