    Check for <sys/sdt.h> as well when determining to enable dtrace probes
    
    Avoids auto-detecting dtrace is present on systems with the ISDN trace tool
    named dtrace installed, but not the dynamic tracing facility named dtrace

    So, like, checking return codes of system calls (signal, etc) is good.
    Also, only restore an old signal handler if one was actually set
    (prevents the server from dying on OS X).

    Fix build on FreeBSD after Popen changes.

commit 6a5066c2e9e872d4ef85ec70745c34d93580177e

    Ignore - not just block - SIGALRM around Popen()/Pclose().
    
    Because our "popen" implementation uses stdio, and because nobody's stdio
    library is capable of surviving signals, we need to make absolutely sure
    that we hide the SIGALRM from the smart scheduler.  Otherwise, when you
    open a menu in openoffice, and it recompiles XKB to deal with the
    accelerators, and you popen xkbcomp because we suck, then the scheduler
    will tell you you're taking forever doing something stupid, and the
    wait() code will get confused, and input will hang and your CPU usage
    slams to 100%.  Down, not across.


Thanks,
Donnie
