devproc buffer overflow, strncpy
in devproc status read handler the p->status, p->text and p->user
could overflow the local statbuf buffer as they where copied into
it with code like: memmove(statbuf+someoff, p->text, strlen(p->text)).
now using readstr() which will truncate if the string is too long.
make strncpy() usage consistent, make sure results are always null
terminated.
