Changed paths:
  M MANIFEST
  M config/auto/headers.pm
  R config/gen/platform/freebsd/sysmem.c
  M config/gen/platform/generic/sysmem.c
  R config/gen/platform/netbsd/sysmem.c

Log Message:
-----------
Make config/gen/platform/generic/sysmem.c more generic.

Include the two most likely methods (sysconf and sysctl) in the
generic file, based on various #ifdef probes.  This way, new systems
are more likely to work without first needing their own sysmem.c file.

If neither sysconf() nor sysctl() seems to work, assume a default of
512 MB.  One could certainly argue for putting an error message here
instead.
