directly reading fields.

MFC r279310:
Since newer versions of compiler-rt require unwind.h, and we want to use
the copy in libcxxrt for it, fix the arm-specific header to define the
_Unwind_Action type.

Ensure that the XHCI driver will refresh the control endpoint settings
when re-enumerating a FULL speed device. Else the wrong max packet
setting might be used when trying to re-enumerate a FULL speed device.
Fix the logic for skipping parameters (with -s) that have "jailsys"
parents (such as host.hostname); these were being skipped all the time.
That it went this long without anyone noticing is a sign that this feature
isn't actually used by anyone, but it's there so it might as well work.
MFC r279123:
Allow for parameters added with the JP_OPT flag to not exist.
That's why the flag exists in the first place.
The __FreeBSD_version was changed to 1001510 to be appropriate for
stable/10.
I will followup with a commit to mpr(4) and mps(4) in head to reflect
the stable/10 __FreeBSD_version and merge the change back to stable/10.

Make sure that the flags for the XPT_DEV_ADVINFO CCB are initialized
properly.
If there is garbage in the flags field, it can sometimes include a
set CDAI_FLAG_STORE flag, which may cause either an error or
perhaps result in overwriting the field that was intended to be
read.
sys/cam/cam_ccb.h:
Add a new flag to the XPT_DEV_ADVINFO CCB, CDAI_FLAG_NONE,
that callers can use to set the flags field when no store
is desired.
sys/cam/scsi/scsi_enc_ses.c:
In ses_setphyspath_callback(), explicitly set the
XPT_DEV_ADVINFO flags to CDAI_FLAG_NONE when fetching the
physical path information. Instead of ORing in the
CDAI_FLAG_STORE flag when storing the physical path, set
the flags field to CDAI_FLAG_STORE.
sys/cam/scsi/scsi_sa.c:
Set the XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE when
fetching extended inquiry information.
sys/cam/scsi/scsi_da.c:
When storing extended READ CAPACITY information, set the
XPT_DEV_ADVINFO flags field to CDAI_FLAG_STORE instead of
ORing it into a field that isn't initialized.
sys/dev/mpr/mpr_sas.c,
sys/dev/mps/mps_sas.c:
When fetching extended READ CAPACITY information, set the
XPT_DEV_ADVINFO flags field to CDAI_FLAG_NONE instead of
setting it to 0.
sbin/camcontrol/camcontrol.c:
When fetching a device ID, set the XPT_DEV_ADVINFO flags
field to CDAI_FLAG_NONE instead of 0.
sys/sys/param.h:
Bump __FreeBSD_version to 1100061 for the new XPT_DEV_ADVINFO
CCB flag, CDAI_FLAG_NONE.

Merge upstream Clang revision 211785:
This commit implements the -fuse-ld= option, so that the user
can specify -fuse-ld=bfd to use ld.bfd.
This commit re-applies r194328 with some test case changes.
It seems that r194328 was breaking macosx or mingw build
because clang can't find ld.bfd or ld.gold in the given sysroot.
We should use -B to specify the executable search path instead.
Patch originally by David Chisnall.
This is a direct commit to stable/10 as this is change is already
included in Clang 3.5 in HEAD. The patch is also reworked slightly for
Clang 3.4.1.

Harden InitListExpr::isStringLiteralInit() against getInit()
returning null.
This led to a crash on invalid code (sorry, no good test case).
Fixes <rdar://problem/15831804>.
This fixes an assertion when compiling certain incorrect code, as
reported upstream in http://llvm.org/PR22684 .
Direct commit to stable/10 and stable/9, since head has clang 3.5.1,
which already includes this change.

Fix ldscripts such that ld(1) collects the .fini_array section in the same
order as the .init_array section. Finalisation routines need to be called
in the opposite order as their corresponding initialisation routines but
rtld(1) handles that by calling the function pointers in .fini_array in
reverse order.

r273865 is part of the work for supporting 4Kn drives, but it turns out
the underlying bug can actually cause corruption of the UEFI system
table in any case where block size is not 512.
Relevant portion of the original commit message:
convert boot1.efi to corrrectly calculate the lba for what the
media reports and convert the size based on what FreeBSD uses.
existing code would use the 512 byte lba and convert the
using 4K byte size.

The runtime linker needs to include a path to itself in the link map
it exports to the debugger. It currently has two choices: it can use
a compiled-in path (/libexec/ld-elf.so.1) or it can use the path stored
in the interpreter path in the binary being executed. The runtime linker
currently prefers the second. However, this is usually wrong for compat32
binaries since the binary specifies the path of rtld on a 32-bit system
(/libexec/ld-elf.so.1) instead of the actual path (/libexec/ld-elf32.so.1).
For now, always assume the compiled in path (/libexec/ld-elf32.so.1) as
the rtld path and ignore the path in the binary for the 32-bit runtime
linker.
Improve support for XSAVE with debuggers.
- Dump an NT_X86_XSTATE note if XSAVE is in use. This note is designed
to match what Linux does in that 1) it dumps the entire XSAVE area
including the fxsave state, and 2) it stashes a copy of the current
xsave mask in the unused padding between the fxsave state and the
xstate header at the same location used by Linux.
- Teach readelf() to recognize NT_X86_XSTATE notes.
- Change PT_GET/SETXSTATE to take the entire XSAVE state instead of
only the extra portion. This avoids having to always make two
ptrace() calls to get or set the full XSAVE state.
- Add a PT_GET_XSTATE_INFO which returns the length of the current
XSTATE save area (so the size of the buffer needed for PT_GETXSTATE)
and the current XSAVE mask (%xcr0).

ulimit(3): Fix broken check.
The existing implementation had a broken comparison that could
overflow and return confusing values. Replace this with a check
that avoids the overflow before it happens.
Consistently return a maximum value also on the case of negative
arguments since negative is considered an overflow and means
infinity for our current setrlimit().

This change introduces new target option "port", that assigns current target
to specified CTL port. On config application ctld(8) will apply LUN mapping
according to target configuration to specified port and bring the port up.
On shutdown cltd(8) will remove the mapping and put the port down.
This change allows to configure both iSCSI and FibreChannel targets in the
same configuration file in alike way.
Kernel side support was added earlier at r278037.

This change allows multiple "portal-group" options to be specified per
target. Each of them may include new optional auth-group name parameter
to override per-target auth parameters for specific portal group.

While ctld(8) still does not allow multiple portal groups per target
to be configured, kernel should now be able to handle it.

Replace iSCSI-specific LUN mapping mechanism with new one, working for any
ports. By default all ports are created without LUN mapping, exposing all
CTL LUNs as before. But, if needed, LUN mapping can be manually set on
per-port basis via ctladm. For its iSCSI ports ctld does it via ioctl(2).
The next step will be to teach ctld to work with FibreChannel ports also.
Respecting additional flexibility of the new mechanism, ctl.conf now allows
alternative syntax for LUN definition. LUNs can now be defined in global
context, and then referenced from targets by unique name, as needed. It
allows same LUN to be exposed several times via multiple targets.
While there, increase limit for LUNs per target in ctld from 256 to 1024.
Some initiators do not support LUNs above 255, but that is not our problem.

For both iSCSI initiator and target increase socket buffer sizes before
establishing connection.
This is a workaround for Chelsio TOE driver, that does not update socket
buffer size in hardware after connection established, and unless that is
done beforehand, kernel code will stuck, attempting to send/receive full
PDU at once.
In conf_apply() remove iSCSI ports from kernel before removing LUNs.
Previous order confused initiators with messages about "removed" LUNs
during simple ctld restart without any real config change. After this
commit initiators only reestablish lost connection, receive "Power on
occurred" UNIT ATTENTION status and continue normal operation.
