List enum values on separate lines to minimize diffs as new types are added. Split the enum values up into groups and use some simple sorting within groups (scalar enums are sorted by size, then base, all other groups are generally sorted alphabetically). No functional change.

/*
|
|
* System call arguments come in several flavours:
|
|
* Hex -- values that should be printed in hex (addresses)
|
|
* Octal -- Same as above, but octal
|
|
* Int -- normal integer values (file descriptors, for example)
|
|
* LongHex -- long value that should be printed in hex
|
|
* Name -- pointer to a NULL-terminated string.
|
|
* BinString -- pointer to an array of chars, printed via strvisx().
|
|
* Ptr -- pointer to some unspecified structure. Just print as hex for now.
|
|
* Stat -- a pointer to a stat buffer. Prints a couple fields.
|
|
* Stat11 -- a pointer to a freebsd 11 stat buffer. Prints a couple fields.
|
|
* StatFs -- a pointer to a statfs buffer. Prints a few fields.
|
|
* Ioctl -- an ioctl command. Woefully limited.
|
|
* Quad -- a double-word value. e.g., lseek(int, offset_t, int)
|
|
* Signal -- a signal number. Prints the signal name (SIGxxx)
|
|
* Sockaddr -- a pointer to a struct sockaddr. Prints symbolic AF, and IP:Port
|
|
* StringArray -- a pointer to an array of string pointers.
|
|
* Timespec -- a pointer to a struct timespec. Prints both elements.
|
|
* Timeval -- a pointer to a struct timeval. Prints both elements.
|
|
* Timeval2 -- a pointer to two struct timevals. Prints both elements of both.
|
|
* Itimerval -- a pointer to a struct itimerval. Prints all elements.
|
|
* Pollfd -- a pointer to an array of struct pollfd. Prints .fd and .events.
|
|
* Fd_set -- a pointer to an array of fd_set. Prints the fds that are set.
|
|
* Sigaction -- a pointer to a struct sigaction. Prints all elements.
|
|
* Sigset -- a pointer to a sigset_t. Prints the signals that are set.
|
|
* Sigprocmask -- the first argument to sigprocmask(). Prints the name.
|
|
* Kevent -- a pointer to an array of struct kevents. Prints all elements.
|
|
* Pathconf -- the 2nd argument of pathconf().
|
|
* Utrace -- utrace(2) buffer.
|
|
* CapRights -- a pointer to a cap_rights_t. Prints all set capabilities.
|
|
*
|
|
* In addition, the pointer types (String, Ptr) may have OUT masked in --
|
|
* this means that the data is set on *return* from the system call -- or
|
|
* IN (meaning that the data is passed *into* the system call).
