fbsd nat: Disable address space randomization when requested.
Use procctl(2) with PROC_ASLR_CTL to disable address space
randomization in the current gdb process before forking a child
process for a new inferior when address space randomization is
disabled.
gdb/ChangeLog:
* configure.ac: Check for <sys/procctl.h>.
* config.in, configure: Regenerate.
* fbsd-nat.c: Include <sys/procctl.h> if present.
[PROC_ASLR_CTL] (maybe_disable_address_space_randomization): New.
(fbsd_nat_target::create_inferior)
(fbsd_nat_target::supports_disable_randomization): New.
* fbsd-nat.h (fbsd_nat_target::create_inferior)
(fbsd_nat_target::supports_disable_randomization): New.
