ffs_isblock:
check if a block is available
returns true if all the correponding bits in the free map are 1
returns false if any corresponding bit in the free map is 0
ffs_isfreeblock:
check if a block is completely allocated
returns true if all the corresponding bits in the free map are 0
returns false if any corresponding bit in the free map is 1
for __do_global_ctors_aux() and __do_global_dtors_aux(),
to fix building with gcc3 -O3.
Discussed with Matt Thomas & Christos Zoulas, and tested on alpha & i386.
called from userspace, and that messes things up.
Thanks to Mark Kettenis to pointing out that not using an alt stack
solved the "loop on gdb sig continuation" issue.
- Rename run_prog() to run_program() and remove the 'errmsg' argument (almost
never used).
- Be consistent about #define<space> in defs.h
- Allow BSDFFS partitions to be FFSv1 or FFSv2 (fixes PR install/23547)
- i386: install correct bootblocks for root filesystem type.
- Do 'fsck -p' before all mounts (but never a full fsck), rename fsck_xxx()
to mount_xxx() and remove some wrapper functions.
- Allow root to be an APPLEUFS partition - and allow them to be newfsed,
should fix PR install/23198
- Redo fstab processing for upgrade to avoid large static data items and
memory leaks. Change walk() to abort on user defined error.
(the fstab stuff really needs more work though...)
- i386: 'Warp' cursor to alternate option when selecting console/bootblocks,
should fix PR port-i386/23546.
- Allow MENU_ok and MENU_yesno to take user defined title.
- Ensure that mountpoint not defined for swap (and similar issues) when
editing netbsd label.
- Tweaks to error handling in run_program(), allow user to say that errors
are expected or that the display shouldn't be cleared before returning.
- Remove some old code that has been festering under #if 0

accepted. However, this time this behavor is not the default. Instead
it must enabled by using the LOCAL_CONNWAIT socket option on either the
connecting or accepting socket.
