sh: Add test for ${01} and ${010} that already works.

Although it is probably unwise to use this, POSIX is clear that leading
zeroes are permitted in positional parameters (and do not indicate octal).

Such positional parameters are checked for being unset and/or null
correctly, but their value is incorrectly expanded.

Fix atf-sh's integration_test

With the move of atf-sh into /usr/libexec in r267181, some of the
tests in the integration_test program broke because they could not
execute atf-sh from the path any longer.

This slipped through because I do have a local atf installation in
my home directory that appears in my path, hence the tests could
still execute my own version.

Fix this by forcing /usr/libexec to appear at the beginning of the
path when attempting to execute atf-sh.

To make upgrading easy (and to avoid an unnecessary entry in UPDATING),
make integration_test depend on the Makefile so that a rebuild of the
shell script is triggered.  This requires a hack in the *.test.mk files
to ensure the Makefile is not treated as a source to the generated
program.  Ugly, I know, but I don't have a better way of doing this at
the moment.  Will think of one once I address the TODO in the *.test.mk
files that suggests generalizing the file generation functionality.

vm_phys: remove limitation on number of fictitious regions

The number of vm fictitious regions was limited to 8 by default, but
Xen will make heavy usage of those kind of regions in order to map
memory from foreign domains, so instead of increasing the default
number, change the implementation to use a red-black tree to track vm
fictitious ranges.

The public interface remains the same.

vm/vm_phys.c:
 - Replace the vm fictitious static array with a red-black tree.
 - Use a rwlock instead of a mutex, since now we also need to take the
   lock in vm_phys_fictitious_to_vm_page, and it can be shared.

The GNU readline library is now an INTERNALLIB - that is, it is
statically linked into consumers (GDB and variants) in the base
system, and the shared library is no longer installed.

That also allows ports to be able to use a modern version of readline

Current code in sysctl proc.vmmap, which intent is to calculate the
amount of resident pages, in fact calculates the amount of installed
pte entries in the region.  Resident pages which were not soft-faulted
yet are not counted.

Calculate the amount of resident pages by looking in the objects chain
backing the region.

Add a knob to disable the residency calculation at all.  For large
sparce regions, either previous or updated algorithm runs for too long
time, while several introspection tools do not need the (advisory) RSS
value at all.
