Modified Files:
        src/sys/kern [netbsd-1-6]: kern_malloc.c

Log Message:
Pull up revision 1.73 (requested by skrll):
add a new km flag UVM_KMF_CANFAIL, which causes uvm_km_kmemalloc() to
return failure if swap is full and there are no free physical pages.
have malloc() use this flag if M_CANFAIL is passed to it.
use M_CANFAIL to allow amap_extend() to fail when memory is scarce.
this should prevent most of the remaining hangs in low-memory situations.
