jdolecek 01040d97a2 add e_path (emulation path) to struct emul, which replaces emulation-specific
*_emul_path variables

change macros CHECK_ALT_{CREAT|EXIST} to use that, 'root' doesn't need
to be passed explicitly any more and *_CHECK_ALT_{CREAT|EXIST} are removed
change explicit emul_find() calls in probe functions to get the emulation
path from the checked exec switch entry's emulation

remove no longer needed header files

add e_flags and e_syscall to struct emul; these are unsed and empty for now

sommerfeld 6b88a0fc51 Emulation stackgap sanity checks, based partly on fixes from
FreeBSD-SA00:42.

Change stackgap_alloc to bounds-check the allocation vs. the stack
gap, returning NULL if there isn't room for the allocation.

Change emul_find() to check for a NULL return from stackgap_alloc()
and convert that into ENAMETOOLONG.

Reorder various emulation syscalls so that all *_CHECK_ALT_{EXIST,CREAT}
calls (which turn into emul_find() under the covers come *after* small,
fixed-size stackgap_alloc() calls.

Clean up ibcs2 {get,set}groups.

simonb 2f1fef39b3 Centralise the declarations of cpu_model, machine, machine_arch,
osrelease, and ostype and remove "extern char foo[];" (for hostname
and domainname too).

Also delete redunctant decl of boottime in kern_info_43.c.

thorpej e3669c3393 Add "use counting" to file entries. When closing a file, and it's reference
count is 0, wait for use count to drain before finishing the close.

This is necessary in order for multiple processes to safely share file
descriptor tables.

thorpej 14cd99880c Fix the shared library versioning snafu caused by the recent changes
to the stat(2) family and msync(2).  This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.

From Frank van der Linden <fvdl@NetBSD.ORG>.
