skipping read-only pages, which can result in valuable non-text-related
data not getting dumped, the ELF loader and the dynamic loader now mark
read-only text pages NOCORE and the coredump code only checks (primarily) for
complete inaccessibility of the page or NOCORE being set.
Certain applications which map large amounts of read-only data will
produce much larger cores. A new sysctl has been added,
debug.elf_legacy_coredump, which will revert to the old behavior.
This commit represents collaborative work by all parties involved.
The PR contains a program demonstrating the problem.

There is no NetBSD devfs, so there is no compatibility issue.

`J' flag means that newsyslog should wait for previously started compression
jobs to complete before starting a new one for this entry. When it is used
along with the `G' flag, in the case when several logfiles match the pattern
and should be compressed, the newsyslog will compress logs one by one,
ensuring that only one compression job is running at a time.
This prevents newsyslog(8) from overloading system by starting several
compression jobs on big files simultaneously.

resource starvation we clean-up as much of the vmspace structure as we
can when the last process using it exits. The rest of the structure
is cleaned up when it is reaped. But since exit1() decrements the ref
count it is possible for a double-free to occur if someone else, such as
the process swapout code, references and then dereferences the structure.
Additionally, the final cleanup of the structure should not occur until
the last process referencing it is reaped.
This commit solves the problem by introducing a secondary reference count,
calling 'vm_exitingcnt'. The normal reference count is decremented on exit
and vm_exitingcnt is incremented. vm_exitingcnt is decremented when the
process is reaped. When both vm_exitingcnt and vm_refcnt are 0, the
structure is freed for real.

Hold the page queues lock when calling pmap_unwire_pte_hold() or
pmap_remove_pte(). Use vm_page_sleep_if_busy() in
_pmap_unwire_pte_hold() so that the page queues lock is released
when sleeping.
