Consolidate all smack routines and checks in a module. We replace and wrap the most commonly used smack routines, which allows removing ifdefs throughout the code. * gl/lib/smack.h: A new header containing the implementation of the wrapped and replacement routines. Note the is_smack_enabled() routine should be optimized out at compile time when compiled on a system without libsmack. * gl/modules/smack: Describe the new module and move the configure time code here from ... * m4/jm-macros.m4: ... here. * bootstrap.conf: Reference the new module. * src/id.c: Use the routines without ifdefs where possible. * src/ls.c: Likewise. * src/mkdir.c: Likewise. * src/mkfifo.c: Likewise. * src/mknod.c: Likewise.
