076574744c Add mkostempsat(3).
This is a variant of mkostemps() which takes a directory descriptor and
returns a descriptor for a tempfile relative to that directory.  Unlike
the other mktemp functions, mkostempsat() can be used in capability
mode.

ab8cabb1ca special-case getvfsbyname(3) for fusefs(5)
fusefs file systems may have a fsname subtype (set by mount_fusefs's "-o
subtype" option) that gets appended to the fsname as returned by statfs(2).
The subtype is set on a per-mount basis so it isn't part of the struct
vfsconf. Special-case getvfsbyname to match either the full "fusefs.foobar"
or short "fusefs" fsname.

This is a merge of r348007, r348054, and r350093 from projects/fuse2

9e92b0f015 libsysdecode: add explicit dependencies on recently changed headers
r349369 removed IP_MIN_MEMBERSHIPS and IPV6_MIN_MEMBERSHIPS, and r349893

This constant determines the number of rights libnv will attempt to

defined by the kernel is machine-dependent and is smaller on 64-bit
kernels than on 32-bit kernels.  To ensure that a 32-bit libnv works
as expected when run on a 64-bit kernel, use a limit that will work
on both 32-bit and 64-bit kernels.

32451fb9fc Add ptrace op PT_GET_SC_RET.
This ptrace operation returns a structure containing the error and
return values from the current system call.  It is only valid when a
thread is stopped during a system call exit (PL_FLAG_SCX is set).

The sr_error member holds the error value from the system call.  Note
that this error value is the native FreeBSD error value that has _not_
been translated to an ABI-specific error value similar to the values
logged to ktrace.

If sr_error is zero, then the return values of the system call will be
set in sr_retval[0] and sr_retval[1].

805eb13a60 Add arm_sync_icache() and arm_drain_writebuf() sysarch syscall wrappers.
NetBSD and OpenBSD have libc wrapper functions for the ARM_SYNC_ICACHE and
ARM_DRAIN_WRITEBUF sysarch operations. This change adds compatible functions
to our library. This should make it easier for various upstream sources to
support *BSD operating systems with a single variation of cache maintence
code in tools like interpreters and JIT compilers.

I consider the argument types passed to arm_sync_icache() to be especially
unfortunate, but this is intended to match the other BSDs.

b54a59f3ba Reduce size of rtld by 22% by pulling in less code from libc
Currently RTLD is linked against libc_nossp_pic which means that any libc
symbol used in rtld can pull in a lot of depedencies. This was causing
symbol such as __libc_interposing and all the pthread stubs to be included
in RTLD even though they are not required. It turns out most of these
dependencies can easily be avoided by providing overrides inside of rtld.

This change is motivated by CHERI, where we have an experimental ABI that
requires additional relocation processing to allow the use of function
pointers inside of rtld. Instead of adding this self-relocation code to
RTLD I attempted to remove most function pointers from RTLD and discovered
that most of them came from the libc dependencies instead of being actually
used inside rtld.

A nice side-effect of this change is that rtld is now 22% smaller on amd64.

   text	   data	    bss	    dec	    hex	filename
0x21eb6	  0xce0	  0xe60	 145910	  239f6	/home/alr48/ld-elf-x86.before.so.1
0x1a6ed	  0x728	  0xdd8	 113645	  1bbed	/home/alr48/ld-elf-x86.after.so.1

The number of R_X86_64_RELATIVE relocations that need to be processed on
startup has also gone down from 368 to 187 (almost 50% less).
