In "automatic" mode allow only growth (with new metadata write); in case
of shrinking destroy the multipath device same as before since it may be

* lex.c (_cpp_clean_line): Add uses of __builtin_expect. Don't
look backward at the end of the line unless we saw a backslash.
* internal.h (struct cpp_reader): Add new fields:
nonexistent_file_hash and nonexistent_file_ob.
* files.c: Include "obstack.h".
(find_file_in_dir): Before trying to open the file, look up the
path name in the hash table of nonexistent files. After failing
to open the file, add the path name to the hash table.
(_cpp_find_file): Cache the results of looking up the file name
starting with the quote and bracket chain heads, if we can.
(nonexistent_file_hash_eq): New static function.
(_cpp_init_files): Initialize pfile->nonexistent_file_hash and
pfile->nonexistent_file_ob.
(_cpp_cleanup_files): Free pfile->nonexistent_file_hash and
pfile->nonexistent_file_ob.

byte positions within the OOB area to support chips with unusual OOB
sizes such as 218 or 224 bytes.
The table for 128 byte OOB works for these but it assumes 3 bytes of ECC
per 256 byte block, and in the case of an ONFI chip the params page may
ask for something different. In other words, this is better but not
yet perfect.

Copy the interesting parameters to a new struct so the rest of the code can
forget about these problems.

The ONFI spec states that at least two bytes of the signature ("ONFI")
must be present, and the CRC must be correct to have a valid parameter
page. If the page is not valid there are at least two backup pages where
the data can also be found.

Fixed various link related issues and 10GBaseT is now linking properly.
Modified the types for the driver tunables to be consistent with the sysctl APIs.

- Fix ALWAYS_INSTALL to take precedence over the FreeBSD ID checks.
In particular, always install a file where the only change was
the FreeBSD ID even if -F is specified.
- Fix the -F option in the case that the only upstream change is a
change in the FreeBSD ID and the local file is removed.
- Add tests for these two cases.
a very hard time to fully understand) with much more intuitive rights:
CAP_EVENT - when set on descriptor, the descriptor can be monitored
with syscalls like select(2), poll(2), kevent(2).
CAP_KQUEUE_EVENT - When set on a kqueue descriptor, the kevent(2)
syscall can be called on this kqueue to with the eventlist
argument set to non-NULL value; in other words the given
kqueue descriptor can be used to monitor other descriptors.
CAP_KQUEUE_CHANGE - When set on a kqueue descriptor, the kevent(2)
syscall can be called on this kqueue to with the changelist
argument set to non-NULL value; in other words it allows to
modify events monitored with the given kqueue descriptor.
Add alias CAP_KQUEUE, which allows for both CAP_KQUEUE_EVENT and
CAP_KQUEUE_CHANGE.
Add backward compatibility define CAP_POLL_EVENT which is equal to CAP_EVENT.

sys/i386/i386/machdep.c:
sys/amd64/amd64/machdep.c:
The value reported by FreeBSD as "real memory" when booting
doesn't match what is later reported by sysctl as hw.realmem.
This is due to the fact that the value printed during the
boot process is fetched from smbios data (when possible),
and accounts for holes in physical memory. On the other
hand, the value of hw.realmem is unconditionally set to be
one larger than the highest page of the physical address
space.
Fix this by setting hw.realmem to the same value printed
during boot, this makes hw.realmem honour it's name and
account properly for physical memory present in the system.

- Move CAP_BINDAT and CAP_CONNECTAT rights to index 0 so we can include
CAP_LOOKUP right in them.
- Shuffle the bits around so there are no gaps. This is last chance to do
that as all moved rights are not used yet.
