Add zfsboot to the scripted interface of bsdinstall(8); oops!
NB: If the zfsboot variables ($ZFSBOOT_*) are set, a script is
assumed to want zfsboot module instead of scriptedpart module.

Add driver for Synchronous Audio Interface (SAI).

SAI supports full-duplex serial interfaces with frame
synchronization such as I2S, AC97, TDM, and codec/DSP
interfaces.
After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA
rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing
any possibility of recovering from the error.

Also, double the timeout to 2 seconds.  Despite what the SD spec says about
all transactions completing in 250ms or less, I have a card which sometimes
takes more than a second to complete a write.
Start getty(8) on ttyu1 as well. It's not uncommon for HP hardware
to have that be the iLO console (e.g. pluto).

Upgrade our copy of llvm/clang to 3.4 release.  This version supports
all of the features in the current working draft of the upcoming C++
standard, provisionally named C++1y.

The code generator's performance is greatly increased, and the loop
auto-vectorizer is now enabled at -Os and -O2 in addition to -O3.  The
PowerPC backend has made several major improvements to code generation
quality and compile time, and the X86, SPARC, ARM32, Aarch64 and SystemZ
backends have all seen major feature work.

Undefine HAVE_VSNPRINTF_IN_STD.

Should fix the build with g++/libstdc++.

This is what we used to do prior the import of atf 0.20 and the build worked
just fine with both libstdc++ and libc++.  Still investigating how to properly
fix this upstream so that we do not hit the same issue on the next import.
After r261980, the local ptr variable in xbox_init() is no longer used,

Remove redundant memcpy of fd_ofiles in fdgrowtable() added in r247602

Fix M_FILEDESC leak in fdgrowtable() introduced in r244510.

fdgrowtable() now only reallocates fd_map when necessary.

This fixes fdgrowtable() to use the same logic as fdescfree() for
when to free the fd_map. The logic in fdescfree() is intended to
not free the initial static allocation, however the fd_map grows
at a slower rate than the table does. The table is intended to hold
20 fd, but its initial map has many more slots than 20.  The slot
sizing causes NDSLOTS(20) through NDSLOTS(63) to be 1 which matches
NDSLOTS(20), so fdescfree() was assuming that the fd_map was still
the initial allocation and not freeing it.

This partially reverts r244510 by reintroducing some of the logic
it removed in fdgrowtable().
