Subject: [PATCH] lrzsz: convert K&R function definitions to ANSI C prototypes

clang-22 with -std=gnu23 fails to build lrzsz because lib/long-options.c and
lib/xstrtol.c still use old K&R-style function definitions, which
newer toolchains reject.

Rewrite parse_long_options() and __xstrtol() using standard prototype
syntax so the sources compile cleanly with modern compilers.
