Aquire Giant slightly later for vnlru.
In the syncer, aquire the Giant only when a vnode belongs to the
non-MPsafe fs.
In both speedup_syncer() and syncer_shutdown(), remove the syncer thread from
the lbolt sleep queue after the syncer state is modified, not before.

This makes updates mounts such as:
"mount -u -o rdonly" work more like, "mount -u -o ro".
References to "-o rdonly" were changed to "-o ro" in revision 1.60 of
the mount(8) man page,
but some people still like to use "-o rdonly" since it was documented
in earlier versions of FreeBSD.

within the jail are never freed. si_cred is only used by the MAC framework so
make the cred reference conditional on it being compiled in, this is not a fix
and will need to be reviewed for any new consumers of si_cred.
This will quell some user complaint when using jails with a default kernel.

sending, once the locks are all unlocked to
do the copy's in, its possible that other
events could then raise the number of bytes
outstanding pushing it so not all the message
would fit. This would then cause us to send
only part of the message. This fix makes it
so we keep a "reserved" amount that can be
kept in mind when making calculations to send.
- rcv msg args with a NULL/NULL for to/tolen will return an error incorrectly
for the 1-2-1 model.
- We were not doing 0 len return correctly and not setting cantrcv more
correctly. Previouly we "fixed" this area by taking out the socantrcv
since we then could not get the data out. The correct rix is to still
flag the socket but alow a by-pass route to continue to read until
all data is consumed.

through scanning its output as ldd(1) returns a non-zero status only
for really abnormal conditions such as an improper file format.
Now cp(1) won't get bogus "not" and "found" arguments if a lib
is missing. [1]
- Don't guess if an element of a complex pipeline is assigned to the main
shell or a sub-shell. Namely use stdio, not vars, to pass lists out from
loops. If using vars, there's the risk that a loop will run in a sub-shell
and the list won't make it to the main shell. It appears that braces and
parens give only limited control over the issue while stdio always works
as intended. Apply this solution to both $progs and $libs for consistency,
although I've failed to go without it only in the $libs part.

with insufficient protection mode.
For the i386 and amd64, create the tunable, machdep.prot_fault_translation,
with the following behaviour:
0 = autodetect the signal to be delivered on KERN_PROTECTION_FAILURE
from vm_fault based on the ELF OSABI note:
no note or __FreeBSD_version < 700004 - SIGBUS/BUS_PAGE_FAULT
note, and __FreeBSD_version >= 700004 - SIGSEGV/SEGV_ACCERR
1 = always SIGBUS/BUS_PAGE_FAULT
2 = always SIGSEGV/SEGV_ACCERR
This would do mostly automatic correction of ABI breakage, with the exception
of the untaged binaries for 7-CURRENT/RELENG_7 before the note is fixed. For
them, sysctl would allow to run the binary with manual settings.
