ext2fs: Fix old out-of-bounds access.

Overrunning buffer pointed to by (caddr_t)&oip->i_db[0] of 48 bytes by
passing it to a function which accesses it at byte offset 59 using
argument 60UL.

The issue was inherited from an older FFS implementation and
fixed there with by merging UFS2 in r98542. We follow the
FFS fix.

MFC 272897:
Various fixes to stats:
- Read the counts of received, dropped, and transmitted management
  packets and add sysctl nodes for them.
- Fix the total octets received/transmitted to read all 64 bits of
  the counters.
- Add missing sysctl nodes for rlec, tncrs, fcruc, tor, and tot.
- Remove spurious spaces.
MFC 271635,271722:
- Only the manpage updates from 271635 are merged to give additional
  heads up for the stricter checks in 11, but the kernel in 10 remains
  permissive.
  - Fail with EINVAL if an invalid protection mask is passed to mmap().
  - Fail with EINVAL if an unknown flag is passed to mmap().
  - Fail with EINVAL if both MAP_PRIVATE and MAP_SHARED are passed to
    mmap().
  - Require one of either MAP_PRIVATE or MAP_SHARED for non-anonymous
    mappings.
- Remove mention of MAP_INHERIT.  It hasn't been implemented for thirteen
  years.
- Remove mention of unimplemented MAP_SWAP.  There are no future plans to
  implement it.

patch(1): Bring fixes from OpenBSD

Check fstat return value.  Use off_t for file size and offsets.
Avoid iterating over end of string.

Introduce strtolinenum to properly check line numbers while parsing:
no signs, no spaces, just digits, 0 <= x <= LONG_MAX

Properly validate line ranges supplied in diff file to prevent overflows.
Also fixes an out of boundary memory access because the resulting values
are used as array indices.
