kernel: make Page.txtflush into an array
To avoid a MAXMACH limit of 32 and make txtflush into an array for the bitmap. Provide portable macros for testing and clearing the bits: needtxtflush(), donetxtflush(). On pc/pc64, define inittxtflush()/settxtflush() as no-op macros, avoiding the storage overhead of the txtflush array alltogether.
