Use kinfo_getvmmap on FreeBSD to enumerate memory regions.
Use kinfo_getvmmap from libutil on FreeBSD to enumerate memory
regions in a running process instead of /proc/<pid>/map. FreeBSD systems
do not mount procfs by default, but kinfo_getvmmap uses a sysctl that
is always available.
Skip memory regions for devices as well as regions an application has
requested to not be dumped via the MAP_NOCORE flag to mmap or
MADV_NOCORE advice to madvise.
gdb/ChangeLog:
* configure.ac: AC_CHECK_LIB(util, kinfo_getvmmap).
* configure: Regenerate.
* config.in: Regenerate.
* fbsd-nat.c [!HAVE_KINFO_GETVMMAP] (fbsd_read_mapping): Don't
define.
(fbsd_find_memory_regions): Use kinfo_getvmmap to
enumerate memory regions if present.
