Fix PR#20520 - predicate called too many times in list::remove_if.
Add tests for list, forward_list, and the std::remove_if algorithm
This fixes an issue where std::list<>::remove_if() and remove() could
erroneously visit elements twice.

While here, change how we check if the current line is the last one.
Before, we just checked if there were more files after the current one.
Now, we check the actual content of those files: they files may not have
a line at all. This matches the definition of the "last line" by the
Open Group.
The new behavior is closer to GNU sed.

mapping size (currently unused). The flags includes the fault access
bits, wired flag as PMAP_ENTER_WIRED, and a new flag
PMAP_ENTER_NOSLEEP to indicate that pmap should not sleep.
For powerpc aim both 32 and 64 bit, fix implementation to ensure that
the requested mapping is created when PMAP_ENTER_NOSLEEP is not
specified, in particular, wait for the available memory required to
proceed.

Correct the usage in both the manpage and in usage() to indicate
that the wait interval and repetition count may be given either
with the respective -w/-c arguments, or as the final positional
arguments. [0]
The corresponding code to implement the positional arguments has
been conditional on the (always-enabled) BACKWARD_COMPATIBILITY
macro since the original 4.4-lite import. It's no longer reasonable
to remove the functionality, so remove the macro and conditional
instead.
Note that multiple disks may be given on the command line.
While here, sort arguments and apply minor mdoc fixes.

nullfs vnode shares vnode lock with lower vnode, this allows the
reclamation of nullfs directory vnode in null_lookup(). In this
situation, VOP must return ENOENT.
More, since after the reclamation, the locks of nullfs directory vnode
and lower vnode are no longer shared, the relock of the ldvp does not
restore the correct locking state of dvp, and leaks ldvp lock.
Correct this by unlocking ldvp and locking dvp.
Use cached value of dvp->v_mount.

Add the ACPI MCFG table to advertise the extended config memory window.
Introduce a new flag MEM_F_IMMUTABLE for memory ranges that cannot be deleted
or moved in the guest's address space. The PCI extended config space is an
example of an immutable memory range.
Add emulation for the "movzw" instruction. This instruction is used by FreeBSD
to read a 16-bit extended config space register.

After r269510 the IO APIC and ATPIC initialization is done at the same
order, which means atpic_init can be called before the IO APIC has
been initalized. In that case the ATPIC will take over the interrupt
sources, preventing the IO APIC from registering them.

have to adjust freeblk records to reflect the change to a full-size block.
For example, suppose we have a block made up of fragments 8-15 and
want to free its last two fragments. We are given a request that says:
FREEBLK ino=5, blkno=14, lbn=0, frags=2, oldfrags=0
where frags are the number of fragments to free and oldfrags are the
number of fragments to keep. To block align it, we have to change it to
have a valid full-size blkno, so it becomes:
FREEBLK ino=5, blkno=8, lbn=0, frags=2, oldfrags=6

take this into account. Alas it breaks source upgrade from any version of
9 because flex is not built as a bootstrap-tools (it would be for older
versions).
That means "libunbound/configlexer.c" is built with the old flex but using
config.h for the new one. Build is thus broken going from 9.* to 10.
Make flex a bootstrap-tools entry if host is less than 1000033 to take into
account the flex update in 10.
Tested on both 9.2-RC3 and 9.3 by myself and dim@. Running buildworld in
head but as both 10 and 11 has the new flex, it will not matter.

One problem is inferior(9) looping due to the process tree becoming a
graph instead of tree if the parent is traced by child. Another issue
is due to the use of p_oppid to restore the original parent/child
relationship, because real parent could already exited and its pid
reused (noted by mjg).
Add the function proc_realparent(9), which calculates the parent for
given process. It uses the flag P_TREE_FIRST_ORPHAN to detect the head
element of the p_orphan list and than stepping back to its container
to find the parent process. If the parent has already exited, the
init(8) is returned.
Move the P_ORPHAN and the new helper flag from the p_flag* to new
p_treeflag field of struct proc, which is protected by proctree lock
instead of proc lock, since the orphans relationship is managed under
the proctree_lock already.
The remaining uses of p_oppid in ptrace(PT_DETACH) and process
reapping are replaced by proc_realparent(9).

swap pager. Swap pager uses a private mutex to protect swap metadata,
and does not rely on the vm object lock to ensure integrity of it.
Weaken the requirement for the vm object lock by only asserting locked
object in vm_pager_page_unswapped(), instead of locked exclusively.
