Clean up some clang warnings about sign conversion
fread & fwrite are defined as taking size_t arguments (an unsigned type),
so stop casting their arguments to a signed int just to confuse things.
Fixes warnings:
AuFileName.c:69:59: warning: implicit conversion loses integer precision: 'unsigned long' to 'int' [-Wshorten-64-to-32]
size = strlen (name) + strlen(&slashDotXauthority[1]) + 2;
~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~
AuRead.c:58:44: warning: implicit conversion changes signedness: 'int' to 'size_t' (aka 'unsigned long') [-Wsign-conversion]
if (fread (data, (int) sizeof (char), (int) len, file) != len) {
~~~~~ ^~~~~~~~~
AuWrite.c:49:46: warning: implicit conversion changes signedness: 'int' to 'size_t' (aka 'unsigned long') [-Wsign-conversion]
if (fwrite (string, (int) sizeof (char), (int) count, file) != count)
~~~~~~ ^~~~~~~~~~~
