In case of math/secp256k1, a very large integer value was used as input

Work around LLVM PR30879, which is about a bad interaction between

This should fix some instances of broken exception handling when

This hack will be removed as soon as upstream has implemented a more

[ELF] Support --{,no-}allow-shlib-undefined

Summary:
In ld.bfd/gold, --no-allow-shlib-undefined is the default when
linking an executable. This patch implements a check to error on
undefined symbols in a shared object, if all of its DT_NEEDED entries
are seen.

Our approach resembles the one used in gold, achieves a good balance
to be useful but not too smart (ld.bfd traces all DSOs and emulates
the behavior of a dynamic linker to catch more cases).

The error is issued based on the symbol table, different from
undefined reference errors issued for relocations. It is most
effective when there are DSOs that were not linked with -z defs (e.g.
when static sanitizers runtime is used).

gold has a comment that some system libraries on GNU/Linux may have
spurious undefined references and thus system libraries should be
excluded (https://sourceware.org/bugzilla/show_bug.cgi?id=6811). The
story may have changed now but we make --allow-shlib-undefined the
default for now. Its interaction with -shared can be discussed in the
future.

clang: default to DWARF 4 as of FreeBSD 13

FreeBSD previously defaulted to DWARF 2 because several tools (gdb,

been fixed or are deprecated.

Note that gdb 6 still exists but has been moved out of $PATH into

build sets the DWARF version explicitly via -gdwarf2, so this should

FPCW contains the rounding mode control which we manipulate to

storing the value to the stack, and then changing the rounding mode

instructions could be scheduled into the middle of the sequence.

This patch introduces the register and adds it as an implciit def of
FLDCW and implicit use of the FP binary arithmetic instructions and

libbe(3)/bectl(8): Make consistent with beadm

vermaden (maintainer of beadm) points out the following inconsistencies:
- "missing command" is not printed prior to usage if the error is simply a
missing command; this should be obvious from the context
- "bectl rename" isn't using the "don't unmount" flag (zfs rename -u), so
the active BE can't be renamed. It doesn't make sense in our context to
*not* use -u, so use it.

Documentation updates reflect the above and note an inconsistency with the
'destroy' command that is consistent with other parts of the base system.

A fix for libbe(3) not properly being installed to /lib is included.
SHLIBDIR should have been added when it was moved in r337995.

Eliminate in-tree usage of arc4random_stir().

include/stdlib.h:

Remove arc4random_stir() and arc4random_addrandom() prototypes,
provide temporary shims for transistion period.

lib/libc/gen/Makefile.inc:

Hook arc4random-compat.c to build, add hint for Chacha20 source for
kernel, and remove arc4random_addrandom(3) and arc4random_stir(3)
links.

Compatibility shims for arc4random_stir and arc4random_addrandom
functions to preserve ABI. Log once when called but do nothing
otherwise.
