    curl_xml: fix 3 small memory leaks
    
    Discovered while testing the previous 2 commits. NB: valgrind
    already complained about these before 0afea606 was applied, so this
    isn't related to issue #935.

    Enable the processes plugin by default on Solaris.
    
    It now builds and works correctly in both 32-bit and 64-bit mode.

commit 469f54386a712ceb7bfe8ec8945bfc7d501d4e59

    processes: Solaris: Consistently use long to represent a pid
    
    pid_t may be defined as an int or a long depending on circumstances.
    Use a long everywhere so we don't have to fiddle with typecasts.
    
    This fixes an issue where an incorrect printf format string would
    be used for a pid_t in 32-bit builds.

commit 242924c08dba2b8ffce9d82a38235f6d6710a136

    processes: Fix build for Solaris 32-bit binary
    
    Work around a #error in <sys/procfs.h> that occurs when building a
    32-bit binary with _FILE_OFFSET_BITS=64. This uses a hack similar
    to the one in swap.c.

    processes: Fix ps_get_cmdline() on Solaris.
    
    Return value of read_file_contents() was checked incorrectly.

commit 0ae43c418801b406f08de47fb467223cf5781669

    zfs_arc: Don't spam the log if we fail to read the "l2_size" kstat value.
    
    The value got lost with some patch to Solaris 10 and has only reappeared
    recently in 11.2. If we ever fail to read this value, stop trying, so we
    don't report an error on every interval.

    oconfig: fix oconfig_free to free all elements
    
    The recursive nature of this function made it difficult to free the root
    node of the config tree. Splitting it in 2 allows to work around this
    problem.
