make: use separate function to include makefiles.
Have Dir_FindFile and Dir_FindInclude call FindFile with a
bool flag to indicate whether .CURDIR should be be searched at all.
Dir_FindFile treat sysIncPath and defSysIncPath as special
Rather than play games with adding .DOTLAST and then having to
exclude that from .SYSPATH, just have Dir_FindFile check if
path is sysIncPath or defSysIncPath and behave as if .DOTLAST seen
and also skip the final search of .CURDIR.
Fix Dir_SetSYSPATH to use defSysIncPath if sysIncPath is empty.
PR/58266: Collin Funk: Fail if from == to, like FreeBSD and Linux. The test
is done in dup3 before any other tests so even if a bad descriptor it is
passed we will return EINVAL not EBADFD like Linux does.
Use native cd9660 blocksize to specify block numbers in cd9660.c.
This reduces diffs from src/usr.sbin/installboot/cd9660.c.
Also explicitly call cd9660_match() to get fstype->blocksize properly.
Sync with src/usr.sbin/installboot/cd9660.c:
- include now properly updated cd9660_extern.h for function prototypes
and remove them from local installboot.h
- use ISO_MAXNAMLEN rather than (BSD specific and incorrect) MAXNAMLEN
- use proper names for the secondary boot file
- appease several pointer signedness warnings (not fatal on HOST tools)
Add cd9660 support to search a bootloader file in the target file system.
Also add CD boot support for hp300, using a bootloader file in cd9660 fs.
This is a tool's part to close PR/54455.
HP 9000/300 machines read LIF directory entry allocated after
the LIF volume header at the top of the boot disk during bootstrap,
and a bootstrap file must be contiguously allocated on the disk
due to limitation of the LIF specification.
Current NetBSD/hp300's bootloader is larger than ~80KB so we have
to prepare a special 'boot' partition for FFS (that has only 8KB (ffsv1)
or 32KB (ffsv2) spaces) disks to put such a large bootloader.
On the other hand, on ISO9660 fs all files are allocated contiguously
so we can specify a bootloader file in the target ISO9660 directly
in the LIF directory entry.
Note we can simply use the existing "append" option to create bootable

Make cd9660_util.c usable in userland tools like installboot(8).
This was partially done for src/distrib/cdrom/macppc_installboot,
but more strict prototypes are necessary for native binary builds.
Clean up the <sys/ucontext.h> <-> <machine/mcontext.h> interface up
a little:
- Define _UC_MD_BIT* constants for the available machine-dependent bits,
and use those constants to define the machine-dependent bits as well
as the machine-independent bits that have machine-dependent values.
- Explicitly generate an error if _UC_TLSBASE, _UC_SETSTACK, or
_UC_CLRSTACK are not defined by <machine/mcontext.h>.
