(xreadlink): Omit size_t* arg. All uses changed.

2001-09-04T20:20:16Z

Use ssize_t, not int, to store result of readlink. Check for ssize_t overflow as well as size_t overflow, as POSIX says the result of readlink is implementation-defined when ssize_t overflows. Remove unnecessary cast to char*. Use free+malloc instead of realloc, as the storage doesn't need to be preserved and it's clearer and can be more efficient that way. (SIZE_MAX, SSIZE_MAX): New macros, if doesn't declare.

include errno.h etc, too
