the write to the ktraced file descriptor (when they used fktrace internally)
would block. Fix by clearing the non-blocking bit in the file descriptor by
default, so that the writes will block. This has the side effect of stopping
the traced process. Add a flag to override (-n) this behavior and have the
trace stop without blocking the traced process (the previous behavior).
Fix lint, add checks to failed syscalls, ansify.
Make ktrace -c default to removing all trace points (not just the default ones).
Make kdump default to dumping everything in the trace file.
Add 'A' (all) and '-' (remove following) to valid -t arguments.
Dump data block of UNKNOWN trace points in hex + ascii.
Make first time output with -R 0 (instead of time since epoch).
Use svis() instead of vis() to get " escaped (as \") (needs fixed libc)
Correctly pass unsigned values to svis()
Update man pages.
- fix command name in SYNOPSIS section of man page.
- link ktrace man page to ktruss man page.
- add executable and man page for ktruss in distrib sets.
