 Log Message:
 - add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total
 address space available to processes.  this limit exists in most other
 modern unix variants, and like most of them, our defaults are unlimited.
 remove the old mmap / rlimit.datasize hack.
 
 - adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
 it is currently unused, but was added a few years ago.
 
 - add a pair of new process size values to kinfo_proc2{}. one is the
 total size of the process memory map, and the other is the total size
 adjusted for unused stack space (since most processes have a lot of
 this...)
 
 - patch sh, and csh to notice RLIMIT_AS.  (in some cases, the alias
 RLIMIT_VMEM was already present and used if availble.)
 
 - patch ps, top and systat to notice the new k_vm_vsize member of
 kinfo_proc2{}.
 
 - update irix, svr4, svr4_32, linux and osf1 emulations to support
 this information.  (freebsd could be done, but that it's best left
 as part of the full-update of compat/freebsd.)
 
 this addresses PR 7897.  it also gives correct memory usage values,
 which have never been entirely correct (since mmap), and have been
 very incorrect since jemalloc() was enabled.
 
 tested on i386 and sparc64, build tested on several other platforms.
 
 thanks to many folks for feedback and testing but most espcially
 chuq and yamt for critical suggestions that lead to this patch not
 having a special ugliness i wasn't happy with anyway :-)
