Linux VM Integration Cleanup

Browse Source 
Remove all instances of functions being reimplemented in the SPL.
When the prototypes are available in the linux headers but the
function address itself is not exported use kallsyms_lookup_name()
to find the address.  The function name itself can them become a
define which calls a function pointer.  This is preferable to
reimplementing the function in the SPL because it ensures we get
the correct version of the function for the running kernel.  This
is actually pretty safe because the prototype is defined in the
headers so we know we are calling the function properly.

This patch also includes a rhel5 kernel patch we exports the needed
symbols so we don't need to use kallsyms_lookup_name().  There are
autoconf checks to detect if the symbol is exported and if so to
use it directly.  We should add patches for stock upstream kernels
as needed if for no other reason than so we can easily track which
additional symbols we needed exported.  Those patches can also be
used by anyone willing to rebuild their kernel, but this should
not be a requirement.  The rhel5 version of the export-symbols
patch has been applied to the chaos kernel.

Additional fixes:
1) Implement vmem_size() function using get_vmalloc_info()
2) SPL_CHECK_SYMBOL_EXPORT macro updated to use $LINUX_OBJ instead
   of $LINUX because Module.symvers is a build product.  When
   $LINUX_OBJ != $LINUX we will not properly detect exported symbols.
3) SPL_LINUX_COMPILE_IFELSE macro updated to add include2 and
   $LINUX/include search paths to allow proper compilation when
   the kernel target build directory is not the source directory.
