assignments for strings longer than 2 chars
- Use strlcpy concatenation instead of strlcat
- Make sure that what remains of iteration of the '_len' variable
for manual char assignment
is done in a safer way so mistakes are less possible
* steam.c - cleanups:
* Use string_to_lower from libretro-common/stdstring.c instead of
its own version
* Some stylistic changes
* Rewrite strncpy calls into strlcpy/strlcat/manual assignment
* Make it C89 compliant
* Some unused variables
- unsafe strcpy/strcat/sprintf were used, so pass 'len' parameters
to detect_{system} functions so that we can use the safer strlcpy/strlcat
calls instead
- thanks to strlcat/strlcpy return values, we can do less string concatenations
and get the same results
- some other miscellanous cleanups
as deprecated.
* Use fill_pathname_join_special in the vast majority of cases where
we can ensure out_path is a new empty string
* Get rid of some extension concatenation with strlcat where encountered
* Some general cleanups with NULL termination of strings that get immediately
passed to strlcpy/strlcpy-adjacent functions
Changed return value of detect_ps1_game function to actuially return a
failure when the Serial couldn't be extracted.
Scanner will then fallback on crc check, and usually ends up finding the
games in the database.
