  msun: remove fabs from Symbol.map, and adjust comment

We have s_fabs.c, but fabs(3) is already provided by libc due to
historical reasons, so it is not compiled into libm. When the linker
does not use --undefined-version, this leads to a complaint about the
symbol being nonexistent, so remove it from Symbol.map.

While here, adjust the comment about some functions being supplied by
libc: while it is true that all these are indeed in libc, libm still
includes its own versions of frexp(3), isnan(3), isnanf(3), and
isnanl(3).

  graid: MFC: unbreak Promise RAID1 with 4+ providers

Fix a problem in graid implementation of Promise RAID1 created with 4+ disks.
Such an array generally works fine until reboot only due to a bug
in metadata writing code. Before the fix, next taste erronously created
RAID1E (kind of RAID10) instead of RAID1, hence graid used wrong offsets
for I/O operations.

The bug did not affect Promise RAID1 arrays with 2 or 3 disks only.
