76d4444c78 When using -lcurses, you also need -lterminfo. 
This fixes the build for sun2, and also builds with LDSTATIC=-static,
since archive libraries don't record inter-library dependencies.

cd0a6973f8 Make the cd builtin accept and ignore -P, which is a kshism that has been 
allowed to leak into POSIX and selects the behavior cd already implements.
Closes PR bin/42557 and also relevant to PR pkg/42168.

I suppose this should probably be pulled up to both -4 and -5...

fcc023545e - 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 :-)

9fa1d120a0 el_gets now sets el_len to -1 on error so we can distinguish 
between a NULL string and an error.
This fixes sh from exiting with libedit now allowing EINTR to return.
We may need to expand this to an errno check in the future.
