d90c7e9853 Introduced the notion of a standard serial driver.
There's no target with more than one serial driver (and I don't see that change anytime soon) so it's a no-brainer to apply the standard driver concept to serial drivers.

200b420562 Export LMARGN_save to C. People might want to preserve this setting in their program.
In turn rearrange startup code in order that LMARGN can be set by a 'constructor' (Do
"initlib" later.)

f723147f04 Streamlined clock rate handling.
* Docs say that CLK_TCK is an obsolete alias of CLOCKS_PER_SEC so there's no point in individual definitions.
* All targets determining the clock rate at runtime can use a common handling.

055c294ac0 Use Timer2 for mouse polling.
This follows a suggestion by Sijmen Schouten in issue #818.
Platoterm64 now works with mouse at 1200 baud.

e4e3dbf756 atarixl: check at startup whether RAM beneath the ROM is in use
If detected, the program refuses to run, preventing a crash.
The check only works with SpartaDOS. I don't have an overview which
DOSes potentially use the RAM under the ROM. Or which other installed
programs might use it.

No additional runtime memory space is consumed, since the change
is in the "system check" load chunk which gets replaced by the
user program during loading.

1cc4fa9356 Atari: fix interrupt handling if extended memory is banked in
Extendend memory is mapped over the main memory in the 0x4000..0x7FFF
area. Many DOSes disable interrupts while extended memory is banked in,
but not all (e.g. SpartaDOS-X).
This change modifies the initial interrupt handler to map in main memory
before chaining to the "worker" handlers.
Since the initial interrupt handler uses a data segment to store the
trampoline to chain to the original handler, introduce a new "LOWBSS"
segment to hold this trampoline. Otherwise the trampoline may end up
inside the 0x4000..0x7FFF area.

Add a link time warning if "LOWCODE" segment lays within the extended
memory window.

842c151edd Replaced _systime with clock_gettime.
We want to add the capability to not only get the time but also set the time, but there's no "setter" for the "getter" time().

The first ones that come into mind are gettimeofday() and settimeofday(). However, they take a struct timezone argument that doesn't make sense - even the man pages says "The use of the timezone structure is obsolete; the tz argument should normally be specified as NULL." And POSIX says "Applications should use the clock_gettime() function instead of the obsolescent gettimeofday() function."

The ...timeofday() functions work with microseconds while the clock_...time() functions work with nanoseconds. Given that we expect our targets to support only 1/10 of seconds the microseconds look preferable at first sight. However, already microseconds require the cc65 data type 'long' so it's not such a relevant difference to nanoseconds. Additionally clock_getres() seems useful.

In order to avoid code duplication clock_gettime() takes over the role of the actual time getter from _systime(). So time() now calls clock_gettime() instead of _systime().

For some reason beyond my understanding _systime() was mentioned in time.h. _systime() worked exactly like e.g. _sysremove() and those _sys...() functions are all considered internal. The only reason I could see would be a performance gain of bypassing the time() wrapper. However, all known _systime() implementations internally called mktime(). And mktime() is implemented in C using an iterative algorithm so I really can't see what would be left to gain here. From that perspective I decided to just remove _systime().
