correct case of several other cx16 kernal calls.

corrected to upper case: cx16 kernal calls CLOSE_ALL, LKUPLA, LKUPSA, JSRFAR, PRIMM, MACPTR.

a289b32053 Revert "added -verafxmul compiler option to use vera fx multiplication routine on cx16"
This reverts commit 690782bf.
It was too risky, using vera (especially fx) transparently in multiple places especially perhaps in IRQ handlers will create havoc unless much intricate care is taken to save/restore the vera state. Better to do vera fx explicitly where the programmer has full control.

dd2463a440 proper fix for the previous commit. + fix for i/o channel reset in diskio.f_seek()
it wasn't the adressing mode, it was that it assumed the pointer variable was always in zeropage (which might not be)
