24b5a81456 Replace ctype usage 
The ctype functions are error prone. The argument is an int which must
be in the range of an unsigned char and is interpreted based on the
locale:

    These functions check whether c, which must have the value of
    an unsigned char or EOF, falls into a certain character class
    according to the  specified  locale. The  functions without the
    "_l" suffix perform the check based on the current locale.

15859bb11e seccomp: allowlist for termux/android 12 
Update syscalls in seccomp policy for termux on android 12. With this
change, xmppipe works with the seccomp process restrictions on termux
but will still crash on exit:

* prctl(PR_SET_VMA): prctl(2) is not allowed by the stdin restrictions

* if prctl(2) is allowed, xmppipe aborts with "bad syscall" on exit. The
  system call doesn't show up in strace(1).
