dtrace stored its PR_RLC and PR_KLC flags in the proc_handle's flags,
where they collided with PATTACH_FORCE and PATTACH_RDONLY, respectively.
Thus, Psetflags(PR_KLC) effectively also set the PATTACH_RDONLY flag.
Since the flags are private to dtrace (at least on FreeBSD), store them in
dtrace's own dt_proc structure instead.
On FreeBSD, either PR_RLC or PR_KLC was always set, so remove code that
would handle the case where neither was set.

Fixes: 4ae6991228 ("dtrace: Add WITH_DTRACE_ASAN")
This option is a blanket for all the DTrace-related software. The option
when enabled passes in -fsanitize=address -fsanitize=undeifned, enabling
ASAN and UBSAN in the following components:
- libdtrace
- dtrace(1)
- lockstat(1)
- plockstat(1)
The option defaults to "no" and is intended as a developer aid.

The pid/killonerror test uses an invalid probe specifier to verify that
the child process is killed. It occasionally fails because the "date"
command is allowed to run long enough to print the date. This is harmless
in this case, but is clearly not ideal.
When the dt_proc_control thread is about to exit, and the dtrace command
forked the child, do not make the child runnable.

At some point the names of these devd events changed. Probably it
happened when importing OpenZFS. Before that, FreeBSD's sysevent_alloc
method didn't create a "class" nvpair in the event, which led to
log_sysevent using the event's ev_subclass field as its type.

Tracing memcpy() would crash the kernel, because we'd also trace the

This drops function `getexecname()` redirection.
Historically `getexecname()` is a compatibility definition. Since
openzfs has its own implementation of function `getexecname()` in libspl
and has been merged into base, the compat header file stdlib.h is
no longer needed and should not be used.
Also without this fix libspl will end up an incompatible version of
`getprogname()` with libc. In particular, if zfs is enabled, programs
such as pgrep in /rescue can be wrongly statically linked with libspl
and will not function properly.

When dtrace starts, it tries to detect if the dtrace klds are loaded,
and if not, it loads them by loading the dtraceall kld. This module
depends on most dtrace modules, including systrace for the native
freebsd and freebsd32 ABIs. However, it does not depend on the
systrace_linux klds, as they in turn depend on the linux ABI klds, and
we don't want to load an ABI module that the user has not explicitly
requested. This can leave a naive user in a state where they think all
syscall providers have been loaded, yet linux ABI syscalls are
"invisible" to dtrace.
To fix this, check to see if the linux ABI modules are loaded. If they
are, then load their systrace klds.

Otherwise, if multiple object files contain references to the same
probe, newish lld will refuse to link them by default, raising a
duplicate global symbol definition error. Previously, duplicate global
symbols with identical absolute st_values were permitted by both lld and
GNU ld.
Since dtrace has no use for probe function symbols after the relocation
performed by dtrace -G, make the symbols weak as well, following a
suggestion from MaskRay.

For the TCP protocol inpcb storage specify allocation size that would
provide space to most of the data a TCP connection needs, embedding
into struct tcpcb several structures, that previously were allocated
separately.
The most import one is the inpcb itself. With embedding we can provide
strong guarantee that with a valid TCP inpcb the tcpcb is always valid
and vice versa. Also we reduce number of allocs/frees per connection.
The embedded inpcb is placed in the beginning of the struct tcpcb,
since in_pcballoc() requires that. However, later we may want to move
it around for cache line efficiency, and this can be done with a little
effort. The new intotcpcb() macro is ready for such move.
The congestion algorithm data, the TCP timers and osd(9) data are
also embedded into tcpcb, and temprorary struct tcpcb_mem goes away.
There was no extra allocation here, but we went through extra pointer
every time we accessed this data.
One interesting side effect is that now TCP data is allocated from
SMR-protected zone. Potentially this allows the TCP stacks or other
TCP related modules to utilize that for their own synchronization.
Large part of the change was done with sed script:
s/tp->ccv->/tp->t_ccv./g
s/tp->ccv/\&tp->t_ccv/g
s/tp->cc_algo/tp->t_cc/g
s/tp->t_timers->tt_/tp->tt_/g
s/CCV\(ccv, osd\)/\&CCV(ccv, t_osd)/g
Dependency side effect is that code that needs to know struct tcpcb
should also know struct inpcb, that added several <netinet/in_pcb.h>.
