297e2bdb8e Make sure the RTree sqlite3_blob handle is reset prior to renaming the table.

dc5ece86ae Remove the CLANG_VERSION macro, since we have learned that version numbers in 
clang are "marketing" and are inconsistent and unreliable.  Builds using clang
will still use the GCC_VERSION macro since clang works hard to be gcc
compatible.

a39284bfa8 Cleanup the usage of the SQLITE_DISABLE_INTRINSIC compile-time option. 
Remove the SQLITE_RUNTIME_BYTEORDER compile-time option.  Use
-DSQLITE_BYTEORDER=0 instead.  Fix a bug in R-Tree that occurs when compiling
on a known little-endian machine without the use of intrinsic byteswapping
functions.

068a251d99 Simplify some code in rtree, to avoid confusing the optimizer in GCC on 
some macs:
gcc version 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00).
Prior to these changes, compiling with -O3 would cause incorrect code to
be generated.  The change to the nodeGetCell() routine is key.  The other
changes are merely cosmetic details discovered while bug hunting.
