Implement tuples, needed to export per-CPU scheduling data.
It is now possible to save and print immutable arrays as below:
..$t = (1, 42, "something");
..printf("%d %s\n", $t.1, $t.2);
Also add support for evaluating builtin in order to save them in variables
(required by tuples)

btrace(8) support to symbolize utrace addresses.
This only works for a single static binary where everything was compiled
with -fno-omit-frame-pointer since the stack unwinder requires the
frame-pointer.
A possible btrace script to capture performace of a single process is:
profile:hz:100 / pid == $1 / {
@[ustack] = count();
}
Then using btrace -p program uprofile.bt `pgrep program` will collect
the information for program.
This is far from perfect but should allow other people to play with this
and hopefully improve work.

Delete the last emulation callbacks: we're Just ELF, so declare exec_elf_fixup() and coredump_elf() in <sys/exec_elf.h> and call them and the MD setregs() directly in kern_exec.c and kern_sig.c Also delete e_name[] (only used by sysctl), e_errno (unused), and e_syscallnames[] (only used by SYSCALL_DEBUG) and constipate syscallnames to 'const char *const[]' ok kettenis@

bt(5)/btrace(8): add support for str() Implement initial support for the str() function, which is used primarily to truncate or NUL-terminate strings from either cli args or args to tracepoints and syscalls. Current implementation only supports cli args and is primarily for compatability with bpftrace. Future work is needed once dt(4) supports builtin args other than long values. Adds a regress test and wires in argument-based tests again. ok mpi@

Implement linear and power-of-two histograms: hist() and lhist() keywords.
This is built on top of maps which are currently built on top of RB-trees.
Improvements are welcome! For example the use of a hashing table as pointed
by espie@.
The following one-liner produce an histogram of power-of-two values returned
by the read(2) syscall:
btrace 'syscall:read:return { @bytes = hist(retval); }'
