commit 5ef28d5a05b33a87e7bcc63f2bfaf3b68d0dd1c4
Author: Josh Stone <jistone@redhat.com>

    Allow capitals in @cast headers
    
    The conversion to regexp_match lost the REG_ICASE, so we need to
    manually allow capitals in the regular expression.
    
    * buildrun.cxx (make_typequery): Add A-Z to the character class.

commit 20f90026bb38608bc4fea2e943d0514dee3b7fc8

    Start using arg vectors for stap_system and friends
    
    Instead of worrying about quoting properly in every command string, we
    can rest easier by launching processes with a proper argv[].  All of the
    stap_system-like functions are converted, but a flat-string stap_system
    is also kept around for now while callers are converted.
    
    * util.cxx (stap_spawn): Take a vector<string> for command arguments,
      convert that to an argv[], and use that for posix_spawnp.  Note the
      conversion to spawnp as well so PATH-searching is still performed.
      (stap_system, stap_system_read): Convert to vectors, but keep a flat
      version of the former for compatibility.
      (probe stap_system__start): Move to stap_spawn, to probe all flavors.
      (probe stap_system__complete): Likewise, move to stap_waitpid, to
      probe when any process is finished; add a pid to track who's done.
    * remote.cxx (direct, ssh_remote): Convert all calls to vector form.
