MFC r248653: ZFS: Fix a panic while unmounting a busy filesystem.
This particular scenario was easily reproduced using a NFS export. When the
first 'zfs unmount' occurred, it returned EBUSY via this path, while
vflush() had flushed references on the filesystem's root vnode, which in
turn caused its v_interlock to be destroyed. The next time 'zfs unmount'
was called, vflush() tried to obtain this lock, which caused this panic.
Since vflush() on FreeBSD is a definitive call, there is no need to check
vfsp->vfs_count after it completes. Simply #ifdef sun this check.

This commit adds a new mode option 'e'.
For freopen() with a non-NULL path argument and fopen(), the close-on-exec
flag is set iff the 'e' mode option is specified. For freopen() with a NULL
path argument and fdopen(), the close-on-exec flag is turned on if the 'e'
mode option is specified and remains unchanged otherwise.
Although the same behaviour for fopen() can be obtained by open(O_CLOEXEC)

Merge 1.12 of pf_lb.c from OpenBSD, with some changes. Original commit:
date: 2010/02/04 14:10:12; author: sthen; state: Exp; lines: +24 -19;
pf_get_sport() picks a random port from the port range specified in a
nat rule. It should check to see if it's in-use (i.e. matches an existing
PF state), if it is, it cycles sequentially through other ports until
it finds a free one. However the check was being done with the state
keys the wrong way round so it was never actually finding the state
to be in-use.
- switch the keys to correct this, avoiding random state collisions
with nat. Fixes PR 6300 and problems reported by robert@ and viq.
- check pf_get_sport() return code in pf_test(); if port allocation
fails the packet should be dropped rather than sent out untranslated.
Help/ok claudio@.
Some additional changes to 1.12:
- We also need to bzero() the key to zero padding, otherwise key
won't match.
- Collapse two if blocks into one with ||, since both conditions
lead to the same processing.
- Only naddr changes in the cycle, so move initialization of other
fields above the cycle.
