* Rename TBUF_LEN and FMT_LEN to _SIZE as they contain a NUL byte.bluhm2017-07-201-11/+11
| | | | | | Change FMT_SIZE to 1024+1 for consistency. Do not loop over the format string if there is no output space left. OK deraadt@ millert@

* port the RBT code to userland by making it part of libc.dlg2017-06-196-13/+728
| | | | | | | | | | | | | | src/lib/libc/gen/tree.c is a copy of src/sys/kern/subr_tree.c, but with annotations for symbol visibility. changes to one should be reflected in the other. the malloc debug code that uses RB code is ported to RBT. because libc provides the RBT code, procmap doesn't have to reach into the kernel and build subr_tree.c itself now. mild enthusiasm from many ok guenther@

* Support swapping 32-bit aligned elements on 64-bit platforms.millert2017-05-241-22/+63
| | | | | Previously they would be swapped a byte at a time when sizeof(int) != sizeof(long). Idea from FreeBSD.
* Document that qsort falls back to heapsort() if the recursion depthmillert2017-05-201-3/+13

* Use David Musser's introsort algorithm to fall back to heapsort(3)millert2017-05-203-16/+47
| | | | | | when the recursion depth reaches 2*lg(n + 1). This avoids quicksort's quadratic behavior for pathological input without appreciably changing the average run time.
