Incorporate bsdiff into the source tree This is needed for the new update system. Info on bsdiff can be found here: http://www.daemonology.net/bsdiff/ The patch I'm about to attach is a modified version of bsdiff 4.2. bsmedberg added a CRC32 value to the header and factored out the bzip2 compression.

Comment on attachment 185079 [details] [diff] [review] v1 patch I'm only looking at the makefile changes. EXTRA_DSO_LDOPTS is only used when linking against shared libs. Also, you'd need to use $(call EXPAND_LIBNAME,...) otherwise the mingw gcc build will complain about the missing Ws2_32.lib file.

This version of the patch includes the following changes: o Build as a host utility (HOST_PROGRAM) since the generated program need not be included in our releases. o Build as C code since there isn't support for HOST_CPPSRCS. (The code was not really using C++ anyways.) cls: In builds that define CROSS_COMPILE, I plan to simply not build this module. I figure that that is fine since it should really only be something we need from our main release tinderboxen anyways. If we need to cross-compile this module at some point in the future, then we would need to cross-compile libbz2 as well.
