51765c6e5c Removed an unwanted button mask table from a VIC-20 joystick driver.
It had put the jump table at the wrong place.  Programs crashed as soon as they tried to initiate the driver.

4aa19494f5 Removed dysfunctional kbrepeatdelay() and kbrepeatrate().
As discussed in https://github.com/cc65/cc65/pull/452 after my premature merge the two functions in question don't work as expected.

Additionally I adjusted several style deviations in the pull request in question.

acf831658f Adjusted to recent driver interface change.
Please note that this change is absolutely untested!

Apart from the recent driver interface change:
- vic20-stdjoy.s was "slightly broken" because it didn't clear x on return from joy_read.
- vic20-ptvjoy.s was "heavily broken" because it returned a totally different set of bits of the first joystick.

7f52a770d9 Removed joy_masks array.
So far the joy_masks array allowed several joystick drivers for a single target to each have different joy_read return values. However this meant that every call to joy_read implied an additional joy_masks lookup to post-process the return value.

Given that almost all targets only come with a single joystick driver this seems an inappropriate overhead. Therefore now the target header files contain constants matching the return value of the joy_read of the joystick driver(s) on that target.

If there indeed are several joystick drivers for a single target they must agree on a common return value for joy_read. In some cases this was alredy the case as there's a "natural" return value for joy_read. However a few joystick drivers need to be adjusted. This may cause some overhead inside the driver. But that is for sure smaller than the overhead introduced by the joy_masks lookup before.

!!! ToDo !!!

The following three joystick drivers become broken with this commit and need to be adjusted:
- atrmj8.s
- c64-numpad.s
- vic20-stdjoy.s

About all CONIO functions offering a <...>xy variant call
  popa
  _gotoxy

By providing an internal gotoxy variant that starts with a popa all those CONIO function can be shortened by 3 bytes. As soon as program calls more than one CONIO function this means an overall code size reduction.

8bd2628d1e Update the missing entries in the kernel jump table for the Vic20 with the actual function addresses.
The Vic20 does not have kernal table entries for the following functions.

;-----------------------------------------------------------------------------
; Functions which are not in the kernal jump table for VIC-20 but are for C64

CINT        := $E518
IOINIT      := $FDF9
RAMTAS      := $FD8D

All other kernal entries are the same as the C64, however, without this change, the startup code fails.

Without this change the vic20.lib builds incorrectly.

d8c31cf1d3 Renamed RAM to MAIN for all disk based targets.
The name RAM doesn't make much sense in general for a memeory area because i.e. the zero page is for sure RAM but is not part of the memory area named RAM.

For disk based targets it makes sense to put the disk file more into focus and here MAIN means the main part of the file - in contrast to some header.

Only for ROM based targets the name RAM is kept as it makes sense to focus on the difference between RAM and ROM.

419eb700b5 Renamed INITBSS to INIT and INIT to ONCE.
The way we want to use the INITBSS segment - and especially the fact that it won't have the type bss on all ROM based targets - means that the name INITBSS is misleading. After all INIT is the best name from my perspective as it serves several purposes and therefore needs a rather generic name.

Unfortunately this means that the current INIT segment needs to be renamed too. Looking for a short (ideally 4 letter) name I came up with ONCE as it contains all code (and data) accessed only once during initialization.

0ee9b2e446 Changed run location of INIT segment.
So far the INIT segment was run from the later heap+stack. Now the INIT segment is run from the later BSS. The background is that so far the INIT segment was pretty small (from $80 to $180 bytes). But upcoming changes will increase the INIT segment in certain scenarios up to ~ $1000 bytes. So programs with very limited heap+stack might just not been able to move the INIT segment to its run location. But moving the INIT segment to the later BSS allows it to occupy the later BSS+heap+stack.

In order to allow that the constructors are _NOT_ allowed anymore to access the BSS. Rather they must use the DATA segment or the new INITBSS segment. The latter isn't cleared at any point so the constructors may use it to expose values to the main program. However they must make sure to always write the values as they are not pre-initialized.

2c975d3642 Create static drivers directly from source files.
Up to now static drivers were created via co65 from dynamic drivers. However there was an issue with that approach:

The dynamic drivers are "o65 simple files" which obligates that they start with the 'code' segment. However dynamic drivers need to start with the module header - which is written to. For dynamic drivers this isn't more than a conceptual issue because they are always contain a 'data' segment and may therefore only be loaded into writable memory.

However when dynamic drivers are converted to static drivers using co65 then that issue becomes a real problem as then the 'code' segment may end up in non-writable memory - and thus writing to the module header fails.

Instead of changing the way dynamic drivers work I opted to rather make static driver creation totally independent from dynamic drivers. This allows to place the module header in the 'data' segment (see 'module.mac').

d6c3bd29ac Renamed JUMPTABLE and cleaned up module.cfg.
This change was suppsed to fix the issue that the former JUMPTABLE is merked as 'ro' while it is actually written to in several scenarios. When drivers are converted using co65 and then compiled into ROMs the JUMPTABLE isn't copied to RAM and therefore the write operations in question fail.

However unfortunately I didn't succeed in changing that :-( Just setting the former JUMPTABLE to 'rw' broke the drivers. So I placed the DATA segment directly after the former JUMPTABLE segment. This made the drivers converted with co65 work again - obviously after changing libsrc/Makefile:235 from '--code-label' to '--data-label'. But the actual dynamic drivers still didn't work as the former JUMPTABLE wasn't placed as the beginning of the loaded file anymore. That effect could be changed by exchanging src/ld65/o65.c:1391 with src/ld65/o65.c:1394 but doing so broke the drivers again :-((
