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.

4e1f5ebf66 When reading dir entry by dir entry, we need to pad out the receive buffer 
to at least a block to make ufs_readdir happy.

3c173d4927 If we loaded an nmagic on a subpage boundary, adjust epp->ep_d{addr,size} so 
that they start on a page boundary.  This is needed so that obreak(2) works
properly.

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.

230876cf26 Merge parts of chs-ubc2 into the trunk: 
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

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.

af8a9059d3 compute the value to be used for e_arglen via howmany(value, sizeof (char *)), 
rather than just "value / sizeof (char *)".  While in these cases the latter
works as well, the former's a better example for other uses to copy (since
it handles the non-integral multiple case correctly).
