* argc/argv are currently unused
* msglen is currently unused
* "default" is a const buffer, but char *cp isn't, so
change default string to be a non-const global string variable
* Make 'cp' private to each context that's using it, which fixes
a "variable shadows previous declaration" warning and makes it
easier to track where it was being leaked between address family
sections
* Remove unused verbose global; things are now done through syslog
* Mark a variable as unused in handle_rtmsg()
Tested:
* FreeBSD/mips32 using gcc-6.4
Each entry actually stores a native pointer, not a uint64_t quantity. While
we're here, go ahead and export the pointer as-is rather than converting it
to KVA. This may be more useful as consumers can map /dev/mem and observe
the entry.

Need to update both link layer address and broadcast address when active link changes for IP over infiniband.
This is because the broadcast address contains the so-called P-key, which is interface dependent.

Leaving zeroing to the clients leads to error-prone pointer
tricks (zeroing needs to preserve the CCB header), and this
code is not performance-critical, so there's really no reason

Before r332974 the old code would sometimes cause a rare lock order
reversal against pagequeue, which looked roughly like this:
witness_checkorder()
__mtx_lock-flags()
vm_page_alloc()
uma_small_alloc()
keg_alloc_slab()
keg_fetch-slab()
zone_fetch-slab()
zone_import()
zone_alloc_bucket()
uma_zalloc_arg()
bucket_alloc()
uma_zfree_arg()
free()
devfs_metoo()
devfs_populate_loop()
devfs_populate()
devfs_rioctl()
VOP_IOCTL_APV()
VOP_IOCTL()
vn_ioctl()
fo_ioctl()
kern_ioctl()
sys_ioctl()
Since r332974 the original problem no longer exists, but it still
makes sense to move things out of the - often congested - lock.

-mno-align-long-strings was a flag maintained by FreeBSD for the
now-deleted in-tree gcc. Upstream gcc has no such flag, so just drop
it.
The flag was originally submitted by bde and committed in 2002 (svn
r97911 & r104455). However, upstream gcc did address this same issue in
2004 (gcc svn r76694 / git 4137ba7ab7a), reducing long string alignment
in general, and to 1 with -Os.

maxphys is now a tunable, ever since r368124. The default value is also
larger than it used to be. That broke several fusefs tests that made
assumptions about maxphys.
* WriteCluster.clustering used the MAXPHYS compile-time constant.
* WriteBackAsync.direct_io_partially_overlaps_cached_block implicitly
depended on the default value of maxphys. Fix it by making the
dependency explicit.
* Write.write_large implicitly assumed that maxphys would be no more
than twice maxbcachebuf. Fix it by explicitly setting m_max_write.
* WriteCluster.clustering and several others failed because the MockFS
module did not work for max_write > 128KB (which most tests would set
when maxphys > 256KB). Limit max_write accordingly. This is the same
as fusefs-libs's behavior.
* Bmap's tests were originally written for MAXPHYS=128KB. With larger
values, the simulated file size was too small.

Statically link rtld-elf with libcompiler_rt on all architectures so
that we don't need to try to pick and choose the bits we need from it
for each architecture (we now leave that to the linker). Compilers may
emit calls to support functions in this library, but because of the use
of the linker flag -nostdlib for rtld's special needs, the library is
not linked as normal.
Previously we had two different solutions. On some architectures, we
were able to extract reimplementations of the necessary builtin
functions from our special build of libc. On ARM, we just linked
libcompiler_rt.
This is motivated by the same issue as D26199 and D27665, but should be
a simpler solution that will apply to all architectures.

libcompiler_rt implements certain functions that clang and gcc emit
calls to as part of their codegen (e.g. for extended width math). Build
it without stack smashing protection (SSP, -fstack-protector) in order
to support building binaries without SSP, especially the dynamic linker.
Besides, SSP is probably not very valuable in this library.

Both FreeBSD and Linux mkdir -p walk the tree up ignoring any EEXIST on
the way and both are used a lot when building respective kernels.
This poses a problem as spurious locking avoidably interferes with
concurrent operations like getdirentries on affected directories.
Work around the problem by adding FAILIFEXISTS flag. In case of lockless
lookup this manages to avoid any work to begin with, there is no speed
up for the locked case but perhaps this can be augmented later on.
For simplicity the only supported semantics are as used by mkdir.

lua: avoid gcc -Wreturn-local-addr bug
Avoid a bug with gcc's -Wreturn-local-addr warning with some
obfuscation. In buggy versions of gcc, if a return value is an
expression that involves the address of a local variable, and even if
that address is legally converted to a non-pointer type, a warning may
be emitted and the value of the address may be replaced with zero.
Howerver, buggy versions don't emit the warning or replace the value
when simply returning a local variable of non-pointer type.

spa: avoid type narrowing warning
Building the spa module for i386 caused gcc to emit
-Wint-to-pointer-cast "cast to pointer from integer of different size"
because spa.spa_did was uint64_t but pthread_join (via thread_join in
spa_deactivate) takes a pointer (32-bit on i386). Define spa_did to be
pointer-size instead. For now spa_did is in fact never non-zero and the
thread_join could instead be ifdef'd out, but changing the size of
spa_did may be more useful for the future.
