Recent compilers have activated some additional
checks which let the build fail. (at least with cygwin)
(Normally it would be warnings but opensc compiles
with -Werror)
GCC 9.3:
In file included from profile.c:27:
profile.c: In function '__expr_get':
profile.c:2273:18: error: array subscript has type 'char' [-Werror=char-subscripts]
2273 | while (isspace(*s))
| ^~
clang 8.0.1:
compat_getopt_main.c:102:22: error: array subscript is of type 'char' [-Werror,-Wchar-subscripts]
rc = toupper(rc);
^~~~~~~~~~~
/usr/include/ctype.h:161:25: note: expanded from macro 'toupper'
(void) __CTYPE_PTR[__x]; (toupper) (__x);})
^~~~
Actually the code is correct as isspace and others
are used here with data type char, and are to be used
with data type int.
So either the compiler should have deactivated
this error, or the ctype.h macros have to be
written so the compiler no longer complains.
As there is also a simple workaround by casting
char to unsigned char, there is no need to wait for one
of the former options to be happen sometime.

simclist.h is changed to either accept a predefined inline and/or
predefined restrict macro or tests for known compilers and sets
simclist_inline and simclist_restrict with the approprate keyword
for the compiler being used or defines them as blank.
The logic used is based on code in OpenSSL-1.1 e_os2.h
For example, "configure" could define inline and/or restrict.
But OpenSC is built on other platforms without a config.h and thus
changes to simclist.h are still needed.
simclist.c is changed by replacing inline with simclist_inline
and restrict with simclist_restrict.
The one and only use of inline in card-dnie.c is removed as there
is no need to have the function inline. This avoids any inline issues.
If inline is needed in other OpenSC code or in card-dnie.c,
simclist_inline could be used.
(Another option is to just remove all inline and restrict keywords
from OpenSC code.)
