Make strndup smaller, safer, faster
...
First implementation was doing:
- strdup (without checking result!)
- strlen
- terminate
- realloc
New one does:
- malloc to shortest +1
- strncpy
- terminate

Optimize LZ4 decompressor
...
Use a walking out pointer instead of &out[written]. This
simplifies the code by 27 bytes and spares 15% cycles.
Tested with both the unit test and code uncompressing
10kB of data.
Renamed the labels for legibility.

Temporary fix for fgets() not using target-specific newline.
...
This patch provides a temporary fix for the issue where the fgets()
function did not use the target-specific newline character to
decide if it has reached the end of the line. It defaulted to the
value $0a, which is the newline character on only some targets.
The Atari, for example, has newline character $9b instead.
This patch is ugly, because the ca65 assembler that is used for
fgets doesn't currently accept C-type character escape sequences
as values. Ideally we'd be able to write:
cmp #'\n'
And this would end up being translated to a compare-immediate
to the target-specific newline character.
Since that is impossible, this patch substitutes the equivalent,
but ugly, code:
.byte $c9, "\n"
This works because $c9 is the opcode for cmp #imm, and the "\n"
string /is/ translated to the platform-specific newline character,
at least when the 'string_escapes' feature is enabled.

Improved/fixed the time() function:

returned via *timep was wrong.
- Reduced code size by 7 bytes.
