* include/glibtop/error.h: Moved 8 static error functions to
sysdeps/common/error.c. This is the end of an big useless code
bloat : expect ~8KB of object size reduction.
* include/glibtop/procuid.h: s/int/gint32/g
* lib/errors.c: (glibtop_error_quark):
* lib/read.c: (do_read), (glibtop_read_l):
* lib/read_data.c: (glibtop_read_data_l): Minor cleanups.
